Cool/Weird Stuff To Do On a Cluster?
Gori writes "I'm a researcher at a university. Our group mainly does Agent Based Modeling of interdisciplinary problems (think massive simulations where technology, policy, and economics meet). Recently, we managed to get a bunch of money for a High Performance Cluster to run our stuff on. The code is mostly written in Java. Our IT support people are very capable of setting up a stable cluster that will run Java perfectly. But where's the fun in that? What I'm trying to figure out are other, more far-out and interesting things to do with this machine — think 500+ Opteron cores, 2 GB RAM per core, a gigabit interconnect with some badass switches, a massive storage array, plus a bunch of UltraSPARC boxes. So at times when there's no stuff to crunch, I'd like to boot the thing up with a 'weird' system image and geek around in the name of science. Try fancy ways of building models, dynamically adding all sorts of hardware to it, etc. Have different schedulers compete for resources. Imagine a Matlab vs. Boinc vs. ProActive shootout. Maybe run plan9 on it? Most of us are not CE/CS people, but we are geeky enough. So, what would be the coolest and most far out thing you would do with this kind of hardware ?"
And save the environment a little bit?
I'd be interested to see how quickly you could fold@home@work on that cluster.
I think that would be an ideal setup to run Vista on. I heard that with SP1 you might only need half of the equipment you currently have.
that it will be fast enough to run Duke Nukem Forever when it gets released.

"So, what would be the coolest and most far out thing you would do with this kind of hardware?"
Instead of pissing around with stuff that may not go anywhere other than a few giggles over lunch.
Why not just rent, or lend it out to people who don't have the funding or equipment that could use this cluster for a better purpose than "playing around"?
Just saying...
Because Gentoo is just hours of fun....
compiling.
compute pi, all the way.
see how many iterations of virtual machines you can run until it crashes .... nethack.
Well, you could try something that no modern computer has been able to achieve, and they think it'll take something on the order of Deep Thought to get it done -- run Windows Vista at a reasonable speed.
McCain/Palin '08. Now THAT's hope and change!
:-)
power it off and go get a blow job. You might like it.
You have a high-performance cluster, and you're running Java? I bet the OS in windows, too.
Have an open framework for members of the open source community to enhance and create new cluster/multicore optimized technologies. Allow us to do render farms or computation of nodes to do whatever sounds cool at the time. Of course the projects have to be approved, and their may be a small fee unless the project looks interesting or you wish to claim it against a donation of resources.
Making love on a Cluster might be considered 'cool' by some, and weird by others.

Being massively parallel it could be interesting to do some AI research. Like chess algorithms or something more fun perhaps a good automated tech support system via chat. Or trying to decode, capatacha. Map optimizations... a bunch of fun stuff. At least it would be for me.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
I run distributed answer set and SAT solvers on them and use these to do things like compose music, optimise machine code, (hopefully soon) find integer overflow bugs in code. Drop me a line if you're interested (mjb in the computer science department, University of Bath).

Write a program that creates every possible 255x255px bitmap possible, and then right an algorithm to go through and figure out which ones are rubbish and which ones are actually recognizable pictures.

There was this one incident when me and this girl turned a cabinet over on it's side and used it as a surface for sex play. That was different. It didn't get weird until she insisted that I tie her wrists with some Cat 5 though.
I'm doing computational condensed matter physics for my PhD. If you give me an account, I can keep your cluster at full load while you're not using it. :) The type of stuff I run can span hundreds of processors over (sorry to say it) slow interconnects like GigE.
If you let me use it, I'll acknowledge you in all publications AND I'll make you some pretty pictures (materials under extreme conditions make for cool figures).

Create a reverse Google bomb - Index every link to say 'george bush' from Google, read each page into memory hash the words, assigning value by count amongst all the pages, and then post the top ten words on GW that are not 'the' 'a' 'was' etc.
Perhaps comparing this to the same process on Paris Hilton would be a report that sparks SkyNet to life. I don't know. Seriously, if those two have 6 of the top ten words in common it would have to mean something.
If you have all that cpu sitting idle, that is the kind of weird shit nobody else would do, but also couldn't not read the report either. Perhaps you'll start something new for Google Trends? :)
Support NYCountryLawyer RIAA vs People
I do burn-in testing on a lot of the machines we get at work, using hardware I can't personally afford.
My favorite test is to find scenes to render with a raytracer.. yafray is my favorite, runs on all major platforms. But not just any scene, it has to have all the details turned up to 11, contain extremely high detail (polygon counts drive up memory usage), and write out an absurdly large image.
Kind of whimsical but it's hard to not be impressed by an image 20,000 pixels square with perfectly accurate reflections. Who cares if I can only fit a fraction of it on my monitor. ;)
...they might have a person or two who might know what to do with it I'm sure.

Or you could try to thermally load them in patterns that produced different tones on the fans (or maybe an AM radio) record it then speed it up. Maybe you could make it sound like a baluga whale.
Or maybe you could implement a virtual machine cluster of 250 cores. The repeat the process till you see how many virtual machines you can stack on top of each other till it has the same speed as a single processor.
While this might sound stupid this would give us a rough estimate of how many watts per virtual world it takes and from that we could figure out how many layers deep in the simulation we actually live assuming the top level one is powered by something less than 1 sol of power.

Since you are at a university already, I would recommend you take computer science classes to understand parallel and distributed computing fundamentals before you go off thinking you can do your "cool/weird" stuff. It's hard to think outside the box when you don't even know what the box is.
So go off and learn about parallel and distributed algorithms first, then distributed computing models, then look at prior scientific applications in MPI, then look at current distributed systems from Microsoft, Google, and IBM, then look at BOINC, and then think how you can do cool/weird stuff.
If you are not using it for something useful, why don't you shut it down, go to minimal power consumption and stop wasting energy?

Get Rails to scale?
I (Mat) work at Vanderbilt University's supercomputing center. Our university supercomputing center was originally a joint venture between the proteomics and high-energy physics departments, but they decided to make it a independent university-wide initiative to bring HPC tools to all users.
Before we founded the center, there were a lot of groups that required computing on campus, but it was highly inefficient. Their local clusters had lots of free cycles (low return on asset) that they couldn't effectively share with other users, the clusters were down quite often (grad students and postdocs are poor sysadmins, plus they should be doing actual research anyway). Several other problems related to either pooling of resources or pooling of knowledge, you get the idea...
I highly recommend setting up a batch scheduler such as Torque/Maui and opening your cluster to all researchers on campus. You'd be surprised how much demand is out there. We have all the usual math/science/engineering/biomedical users, plus users in more esoteric fields (nursing, accounting, music, psychology). You can always give your group a higher job priority if needed. It gives a higher return on asset and gets lots of goodwill on campus (and, potentially, at funding agencies). You can charge users for support, storage, etc for cost recovery, or even use it as a revenue source if your grants allow.
Having different types of users also allows cross-pollination of ideas. We have a large number of biomedical researchers who are now using a high-energy physics software (geant), biomedial people who are teaching other users how to program in R, etc. These are avenues for research/discovery that didn't exist before.
Play a digital version of hide and seek. Flip a certain register on only one of the memory chips and have competitions on who can find it the first.

That way you can backfill the resource with jobs from VOs (Virtual Organizations, think projects/groups) you choose. It is similar to BOINC in the sense you can pick what science to support.
The idea is that the sharing will go both ways. You will give spare cycles to other users on OSG, and in return, you will be able to use spare cycles on other resources.
Spend some time on the OSG website reading the things under "Learn About Us". Also check out the research highlights to see what kind of science is being done on OSG resources:

I can't think of anything geeky to do with it, but I have a noble cause. I am an undergrad doing research in the field of bioinformatics. Your cluster sounds like it could do the work I need done in around one day. Our university's(Texas A&M) supercomputer could handle it, but they don't let undergrads have more than 30 hours. Furthermore, I cannot even use it during the summer because I am not enrolled until the fall. If you would/could help me please respond to this post with a way to contact you. Thanks

Most researchers have to fight tooth and nail to get funding, or even access to, that kind of hardware. You get it without even a plan to use it? Send it back. Save your sponsor's money.
Construct some scenarios to test emergence. Like the game of Life, with the potential to form much more complex outcomes. There'd be some software writing involved to get the project off the ground, after that it's a matter of coming up with different rules for interactions, or different properties for the 'organisms'.
I think it'd be really interesting to see what complex structures evolve out of different sets of simple rules and interactions. Who knows, you may even discover something incredible in the process.
Murphey's fighting Occam, and we're in the stands.
... I think looking into problems that other industries (i.e. video games/software/etc) is a good place to look for interesting problems, problems that need to be solved because of performance issues, like things that are on the cutting edge of mainstream performance in PC's. Try to focus on how to develop X given computational constraints Y.
I think that might be very interesting.
I agree. Fold on it. Just make sure you fold for team 24.
You can try to launch a really big and nasty simulation of the universe. Those produce really nice pictures and eat up all your processor power. Just don't let this kind of power unused, it is a waste :)

Convert from Java to Fortran (or C++) and your code will run an order of magnitude faster. I bet you can do even better than that. Seriously. You are wasting so much CPU time with Java. This way you can reduce the size of your cluster and save lots of money. Probably taxpayer dollars right? You have some responsibility to the funding agencies.

How about simulating tentacles physics for future 3D hentai games?
I was administrating a 32-node cluster of high-end PC-style computers, lined up across a room on a big metal shelf. Each of these computers had a CD-ROM drive, so I wrote a little script to make the cluster do "The Wave" with their CD trays. I had random people coming into the server room for months asking to see the computer wave.
Sure, fractal exploration programs are nothing new. But what about building the deepest image of the Mandelbrot set out there, or some other set?
Seriously, though, if you guys do "massive simulations where technology, policy, and economics meet", I'd like to see some simulations of the global economic and environmental consequences of rapidly rising energy prices, or calculations of how much waste heat contributes to climate change.
Seriously, with that utter lack of plan and vision, how did you ever get a grant? Why don't you give it up and let someone who needs the research money have it?
If you don't have jobs in a never-ending queue, then you just don't need a system the size you're talking about. "Real world" HPC clusters are maxed out at all times - they can't get enough CPU. Sounds like you're just getting a new play toy. And really, Java? Pluh-eez...
Prize money in the $100K and up ranges are available for primes that are found above 10 million digits. If you can get the cluster to search for a 10 million digit prime and you end up finding it, you'd earn your Department a cool $100,000 in extra funding. I haven't read the exact rules for the Prime95 program invlovement, but you'd still get a good grant for your Dept. from just crunching 1s and 0s on your idle processes.

Couldn't you be doing something yourself to save the environment right now - something like turning off YOUR computer instead of browsing slashdot? Oh, wait - that would require YOU to do something.

A variant on the rendering theme: Instead of simulating rays, simulate light wavelets and the modern theory of light. You should have enough compute power there to render reasonable scenes using such a technique.
Fluid dynamics: This is a popular one, and NASA offer source codes for free for subsonic, supersonic and even hypersonic flows. In fact, they offer quite a number of subsonic ones. They're also not the only source. There's several open-source CFD packages, ranging from river simulations to aircraft simulations.
Supernovae simulation: There are packages (freeish, rather restricted in access) that allow you to simulate thermonuclear and supernovae explosions within stars. The restrictions are for rather obvious reasons, even though the odds of anyone nasty obtaining a star is, well, unlikely.
COLOSSUS: There are still a couple of ENIGMA ciphers that have never been broken, which can be obtained along with the algorithm Colossus used in World War II to crack such codes. You could complete the set and maybe discover some lost secret (yeah, right).
BLAST: Other posters have suggested renting out the computer time, but that just transfers the problem of what to run, rather than solving it. BLAST, or one of the MPI-based variants thereof, is an exceedingly popular tool for examining nucleotide sequences, but as the databases grow ever-larger, the demand for ever-more information also increases, creating a need for significant compute power to produce the volume of results desired.

First, go with at least 10e interconnects if at all possible. That many "machines" can chew up a lot of bandwidth just tying to stay in sync.
Second, scrap JAVA and re-write it in C (straight C... easier to optimize)and use hand coded assembly at the performance hot spots. I like JAVA well enough, but its not exactly a "high performance" language.
You should see a LOT more bang for the buck if you do that.

I've worked with supercomputer class systems in the past, common question - "what can I do now?"
Two suggestions:
1. Set aside the first couple "downtime" sessions to run your crazy "OMG it actually worked" stuff out of the way. The stuff you'll brag about for years to come.
2. Every time thereafter, set it up with a grid computing client. Seriously. It may not take advantage of the interconnect fabric, but you will be doing your fellow humans a great service.
Check out http://www.worldcommunitygrid.org/ for some ideas (from a big company whose sponsored code will not cause infinite loops on the nodes....).
SETI is IMNHO a complete waste of time.. if or when the aliens want to be found, it will probably be in Hollywood ID4 style and not some little green guy screetching "Can you hear me now?" on all frequencies and modulations.
Basically, you have a huge cluster and you want to do something fun.
Created a distributed controller application that spawns various systems and processes. When a group of controller nodes no longer detect one running... move it out of the group and reform another control node. Next, that group of nodes spawn another controller and move the address over to the new node.
Now, inject some random madness so nodes break on occassion. (Make it variable so you can pop nodes off left and right if wanted).
I say if you can perfect that then you can do something else with your randomly unreliable application cluster.
Who knows what kind of madness might spawn from that.

Why on earth are you running Java on a high performance cluster? Perhaps you could use all that horsepower to develop, say, some nice high performance software?
You might want to take a look at SAGE as a platform option for that cluster. Then you should be able to farm out jobs from Matlab, Mathematica etc.

Allow OSG users on it. http://www.opensciencegrid.org/ It is a grid of HPC machines that researches who aren't lucky enough to have their own cluster can use time on. I used to admin a cluster at Penn State and we allowed OSG people to use any resources that we weren't using. You don't need to give anyone local access, everyone has a certificate and submits job over the grid, no local access needed.

That sounds like an awesome setup. I can see something like a botnet being run on it, it would really kick ass if you had the bandwidth. Shame you went with the GigE setup though, you're really taking a hit not using InfiniBand on a setup like this.
Install some molecular dynamics simulation software, build a system to model a yeast cell in sugar solution. It would take a few thousand years in all atom mode, but you could do a coarse grained version faster.

Let me second that. I work in NeuroImaging at Uchicago, and since we were given cluster and TeraGrid access we got neuroimaging folks using R and SWIFT (Grid parallel workflow language), and High Energy Physics folks implementing their signal analysis methods on neuroimaging data. They used to say that physical distance (in yards) is a good prediction of collaboration potential in academic departments. These days, sharing a computer cluster seems to achieve a similar thing. But, if you are asking how you can contribute, try setting up your system to load virtual machines on each node -- If you can get that going you'll find many potential users that couldn't bother with adapting their code to the cluster, but would be glad to load an image and run a job in it.
How many points you can rack up in the Folding contest.
That's the most interesting thing you can do with this cluster.
Reading Slashdot dulls creativity sometimes... I suggest you deprive yourself of sleep, overdose on caffeine, read something by Neal Stephenson (Snow Crash or Diamond Age), and meditate on your question with a 2-3 geeky buddies of yours around 2am.
1) Find a picture/piece of code/ISO image/etc. you'd like to compress. Treat it as a very big number. Now find a prime number that comes very close to it. Compress it by treating it as the Nth prime + the remainder. Repeat for the remainder See if the compression is any better than bzip. (I think i saw something like this done for the DeCSS code once...)
2) Find something to optimize via brute-force. (My favorite is neural nets predicting time-series). Run a distributed simulated annealing algorithm. (Run an instance of the algorithm on every core, check every N cycles to see which core is more "optimal", share the parameters with the rest of the instances).
3) Create an interactive multi-user raytraced environment. Get someone to bring in an ImmersaDesk or a CAVE. Stun all visitors.
4) Model a giant neural network. Teach it to do something cool in real-time with your favorite training algorithm...
5) Get dictionaries from 50-60 languages. Write something to correlate similarity of words meaning the same thing. Make pretty graph clustering them by similarity. Post pretty graph on Slashdot.
6) ???
7) Profit!
Given the costs of producing IMAX moves (millions of dollars each) this could be a very inexpensive IMAX movie, even if you had to purchase the cluster.
Hell, forget IMAX, just render a big-ass movie and seed it on thepiratebay.

You need to subtract your exponents not divide them. 2^65025 / 2^41 is 2^64984
(consider a simpler example: 2^10 / 2^2 is 256, not 32)
Because the Java codes I have to optimise to run on our cluster (or SMP machine) still run like lame, wet dogs. I'm sorry, but Java's performance is really, really shitty and I'm considering removing Java and Javac from the systems altogether. When you compare another object oriented language, like C++, at least with that you can write your codes to make use of multiple instructions per cycle ... and then with a good compiler and appropriate hardware, you can vectorize the instructions themselves. When you have codes that for a single processor, would run for about 50.9 years (an example I pulled from just today) those 'simple' little things go a long way. Now where can you tweak that sort of thing in Java? ... Oh, that's right, YOU CAN'T.
But that's object oriented languages (which is getting better since I'm learning how to make myArray[i] run twice as fast), I prefer to use C and fortran. Those babies are low memory and totally rock. You don't spend all your time making method calls, which chew cycles for each call (let alone being in large nested loops).
I don't mind punching out Java code; it's extremely good for some tasks, but it is not a language I'd use on a high performance system. Just in my experience. I could be wrong and would love to be proven wrong.

Wulll Lesee,
My fun with home clustering was mostly done on Dyne:Bolic 1.4.1 the last of the OpenMosix releases.
For me the ability to farm out some audio effects rendering on large tracks to my home network was a gas.Ripping cds to mp3 made the datarate from the cdrom the slow part.I'm not really a video guy but it must be cool to render video stuff without the wait.3d rendering I'm sure.
Others would have you run some socially conscious @home program.Others still would have you crack encryption for good or evil.Some would even have you crunch numbers for everything from gambling to politics.
I suppose fun could be as creative as running
a simulation of a world based on John Lennons "Imagine" You could create a virtual projection of a world where Environmentalists do cleanup in the meatworld where it will do some good instead of on a cluster "spinning" a world for political power.What a kick.

Hm...got Cuda and high powered nvidia graphics on each one? Youv'e got yourself one heck of a Folding@home GPU machine.
A number of other posters have suggested this answer, but I wanted to emphasize it.
You are lucky enough to have a massive, desirable resource that is underutilized while we are in the midst of an academic funding environment which has been called the worst ever for supporting basic and applied research. You, as an academician, have an unwritten duty to help other academicians, and so rather than think of geeky ways to mess around with your new toy, why not share your wealth?
Here are the advantages:
1. You can wrangle additional publications out of it by being an author on published papers by providing sufficient support. Publications are the lifeblood of academics.
2. You can use it to leverage improved relations (or establish relations) with other departments within your university, or across universities. This might not seem like it would be worth much to you, but it will be impressive to your supervisors and department heads (they can take credit for it), and will make you look good in their eyes.
3. You can leverage it to good-news PR. University administrations love good PR. Talk to your PR department. Involve your department.
4. You can do good in the world.
I, personally, run an analysis of neural recordings every so often using Matlab that takes about a week on a reasonably modern dual-core system. It sure would be nice to have that finish in 1/500 as much time! There are about 20 or so researchers who are doing work like mine, and none of them, to my knowledge, are using a high-performance computing environment to analyze their data. It just isn't within their means. I'm not talking about some esoteric, arcane basic science research (although I'm a huge, huge proponent of that), but helping the paralyzed to walk again.

Try to find the least power consuming configuration that works under full load.
Then, starting from that point try to find the best way to automatically adjust between idle and full load (think disabling/enabling cores).

Whoever posted this is a hypocrite. If they practiced what they preached they wouldn't be 'uselessly' using their electricity browsing and posting to slashdot. The same hold true for everyone who modded this up. If you guys *really* believed in saving electricity and whatnot - I mean really took it seriously - you wouldn't be on here in the first place. How many of you slashdot eco-warriors actually just go along with sentiments like this just because it sounds cool and trendy? My guess is, every single one of you - at least those of you who aren't posting from your heavily customized, solar powered laptop from deep within some rain forest you're busily trying to save. If you're going to support this kind of thinking, put your money where your mouth is and make your houses/lives really and truly eco-friendly. I'm betting that simply going through the exercise of trying to do that would scare most of you straight. Failing that, you're nothing but hypocrites and - as such - deserve only to be scorned and mocked.
So at times when there's no stuff to crunch
So just that I understand this correctly. A university gets acces to such a badass piece of hardware which seems to me as a pretty expensive toy and basicly you're wondering what the fuck to do with it?
This seems like a pretty big waste of money to me. I'm sure there are lot's of other uni's and research groups who'd die for such a machine and would make sure that thing would be working it's ass of 24/7 for the couple of years at least.
Life starts at the end of your comfort zone.
Interesting definition of "high performance cluster" you have there.
Gigabit interconnect? Running your simulations in java?
I have no idea what kind of simulations you're running there but I seriously question the price/performance ratio of Opteron hardware for such an application. Sounds like you could save a ton of money by building your cluster from off-the-shelf hardware.
Also, it looks like your sarcasm detector is broken. You might want to get that fixed.

Recently, we managed to get a bunch of money for a High Performance Cluster to run our stuff on. The code is mostly written in Java.
Wait...let me get this straight. You just bought a high performance cluster but your high performance apps are written in Java? HAHAHAHAHAHAHAHAHAHAHAHA!!! That's funny. Let me guess, you couldn't find anyone who knew Visual Basic? You know, if you had written them in something a little faster like C or C++ you could probably run it on a single 4-way box instead of needing an entire cluster.

Many potential users don't realise or don't have the skills to use the power of a supercomputer and there's nothing more fun, or cooler looking on your CV than doing some truly innovative research outside your own field. You look like you already have the skills necessary to collaborate across the traditional subject boundries.
In any case, who needs a supercomputer to tell you politicians are corrupt?

Java is fine for a lot of things, HPC isn't one of them. When you are talking about running hundreds of Java processes, the overhead of the VM becomes significant. I prefer to write all of my HPC code in C. I do this for a living at a genetics research lab where a lot of the biostatisticians and statistical geneticists love R, a interpreted statistical analysis language, and one researcher had a R script that used R MPI to do parallel computing on our cluster. I showed him how to rewrite a couple of his tight loops in C and call them from his R script. The result was that the serial performance on his workstation was now about the same has his old parallel R only version running on 32 CPUs

While you're at it, crank out a few more digits in pi.
A while back someone made a nifty little executable that when executed would create a duplicate of itself and then after a time execute the duplicate (I think it was 60 seconds or something).
The twist is that the program would have random chance of mixing up bits of itself when duplicating itself (mutating if you will). Some mutations would break the resulting executable rendering it 'sterile', some mutations cause the filename of the executable to be different than expected etc etc. The point is the mutation was pretty much random in what code it changed. This process would continue untill the computer froze after being overrun by thousands of little executables running and duplicating themselves every 60 seconds. All that was needed was a simple reboot and the system would be working fine again (albeit there would be a directory full of executables).
I believe the original creator found some interesting results after leaving his machine on for a while... some of the progranisms were in different directories, others had weird names, and a bunch of other stuff I'm probably forgetting.
I'd imagine a super computer would yield some pretty cool results...
Or of course, you could always do what I'd be tempted to do... Install WoW (using wine if needed) and then brag in trade channel about massive your computer is...
There are a lot of things a cluster could do. Even this;

The apricot project is working on integrating crystalspace (game engine) and blender (3d modeling program). Both of which are open source. Rendering created content take a lot of processing power. Blender supports distributed renders, and I'm sure the artists using blender would love to have a render farm they can submit work to. set it up to stream videos back to test them, and then finished renders people are happy with they could download the whole thing.

You see, "intelligent" man has only been around maybe a few million years. That is insignificant compared to 20 billion. In order for us to "see" aliens, we both have to be sufficiently evolved at the same time so we can chat.

Gory, how quickly do you manage to boot all 500 cores to a 'weird' system image of your choice?
This is quite obviously a pretty expensive setup, purchased for a particular purpose. I know that if my department's budget were tapped for this hardware, the first time someone needed to use it for its intended purpose, and your shit was in our way, you'd be looking for a job some place else. There is a time and place to "geek out" and on unused hardware that you find a new use for, that's fine, but a HPC that you want to play around with, its not. Go play somewhere else, this is not a toy.
How about renting out the spare time to smaller university professors that would like to do chemical modeling or something that they've been working on but don't have the raw computing power to speed up their work? I know there are some cool things being tried but the results take a long time because the models take a while to run on second rate (albeit pretty good) modeling setups.

Ok, here's my take. (Full Disclosure. I work at a university. Possibly the one he speaks of.)
Let the students run projects on them. Offset the 30 to 50 KVA power use with dumb terminals for everyone. All these companies donate to research and ignore the educational aspect of universities. The student labs are, at times allowed to become decrepit and old until someone notices. Then the professors, who don't visit the labs normally, come downstairs once in a while and poke fun at them. Rather than poke fun at them, they should do something about it. No, they'd rather serve their own interests and get the donations for their own projects rather than actually help the students. Universities are a political mess when it comes to the professors. Each have their own agenda and communication is always lacking between them.
Many research donations are only for research and student labs are not allowed to use them. Then again, many student lab donations are only for student labs and research groups aren't allowed to touch them. These donations just have too many strings attached. It's a convoluted mess. It's too bad the donations can't just go where they are needed. Rather, they are granted to the people with the best social contacts and the people who best know how to game the system.
The labs here have 6-8 year old systems with CRT's. Yes, CRT's. Here we have a new computer cluster being installed, but the general student population will not benefit. Unfortunately, it's earmarked for "research." What kind of research? I don't know, and obviously, Gori doesn't either. With most projects, students can't use it, unless they join a particular research group. So a handful of students get to play on the new cluster, while several thousand are stuck on decrepit old systems with blurry screens. Make a change and allow classes to be taught from them. Allow students to run their projects on them. A few may actually come up with useful parallel processing projects on them if given a chance.
As with the majority of research projects, they stop as soon as the Professor leaves. Many projects last 1-3 years, then the systems sit idle. Some projects are idle as soon as they are delivered. Rather than waste the 30-50 MW on the new cluster just idling, it would be prudent to allow students to use them. New students arrive every year and classes taught to utilize these systems work best if they're working directly on them. These systems will get more optimal use that way. To offset the power load of this cluster, the computers that people use in their offices and the labs should just be replaced with dumb terminals that run of the cluster. It will consolidate all the data on one system. Administrators should not be carrying around computers with disk drives containing data that may be lost. Data security will be a bit simpler. Back to the mainframe model we swing.

Well firstly, you could consider doing some exhaustive enumeration of chess moves. You've got plenty of compute power there, see what you can do.
Second, the field of Heuristic Search offers many many opportunities to eat up computer power, and some of them have financial prizes attached.
