Linux And Los Lobos Supercomputer

This server really kicks your ass! It kicks your face, too. It kicks your balls into outer space!

Not only are you not funny--your .sig is beyond retarded. Just FYI.
HAH. Have you even looked at any of the SGI IRIX machines? Go to SGI.com... they have scalability up the wazoo. Check out the cray stuff. Be enlightened. Be DeFUDed. HAH.
Myrinet boards do of course use PCI slots. They have to plug into some kind of bus, and PCI is generally the fastest one available on most PC's. They are not Gbit-Ethernet, nor even ethernet. They are a proprietary device. One of the problems in using them with MPICH is that MPICH is not thread safe (or even fork/exec safe) so SMP processors within the same box require external network traffic to communicate to each other. SMP is supported in MPICH (via shared memory) but not for Linux! The authors excuse is that mmap in linux is non standard. Of course there are other fast hardware devices (Giganet, Scala, etc) and other MPI libraries (MPI/Pro) that work quite well with linux.

I think you should run down to the bookstore and get more Lobo paraphenalia...indeed. The article negelcted to mention this is an AHPCC project. Also the MHPCC is getting a set of similar nodes as well. btw, mrc rules.
In the previous article is says this system
would be #24, but this is not true.
Top500 uses GFLOPS mesured from linpack runs,
not peak FLOP numbers.
There is a big difference, esspecially when
using PIII cpu's with low memory bandwidth.

facts do not lie. while the original poster may be a bit fanatic, he is essentially right.
IRIX and scalable do not belong in the same sentence. most IRIX machines cannot stay up for longer than 15 minutes.
Linux is the true industry leader in regards to scalability and security.
Can you imagine the power consumption, noise and heat involved in having a bunch of old 486s sitting there running? How worthless... that's what always cracks me up about these Beowulf posts. If you are a college computer club that had a bunch of old Pentiums and ethernet hardware donated, and you had a free room and electricity from the college, then okay, this would be a fun, low-cost project to mess around with. Otherwise, who cares?

I wonder how fast this thing will run SETI?
He's not close to reality (at least not _THIS_ reality - I'm sure the world in his mind seems very real to him :o) He said that intel hardware is better - which (if you've compared it to anything else on the planet), is a load of crap. I love my PC - I love Linux, but let's pull our head out from the sand - pretty much every current computer architecture is better than x86.
Beowulf is a proper name and as such it would be "Beowulf" in Spanish, Chinese, etc. Has nothing to do with wolves per se.

Just think! If Slashdot had all of that CPU power, it could be used to determine if articles were being posted more than once! AC
I thought that LOBOS was supposed to stand for Loads Of Boxes On Shelves.......Isnt that the idea
Thanks for asking!
Uhm... Thats exactly what Beowulf is good at... Several Beowulf cluster contains different hardware, and at least one is built out of assorted donated PC's of all kinds. If you want to add non-x86 machines that too is simple (unless you want to migrate processes, that is).
Actually proper names are often translated. For an obvious example: Spain certainly isn't Spain in Spanish... ;)
You are either

b) Flamebaiting

Since I don't know which is true, stop using the stove just in case.

actually the poster is very close to reality. i would say 1 year not 6 months, but effectively linux has a superior product to solaris and is kicking ass in the enterprise datacenter market.
linux is the future and more importantly the only future for unix. get on the revolution or get run over.
and I almost had my karma up high enough for that (Score:2) :(
I see even classic Slashdot is now pretty much unusable on dial up anymore.
I was looking for this on Top500.org(the top 500 super computer site) and i couldnt find this one. Is that site updated daily or what? Also... Ive noticed alot more Beowolf Clusters lately, this could start to become even more commmon place and start to change the face of computers and POWER. Or maybe they should start to make 500 processor mother boards.
As I said, you don't need SMPeabilty to cluster, a bunch of Athlons will do nicely (depending on what you wanna do, maybe you'd want different CPUs: Alphas, PPC, whatever).
:)
For that matter you can chain anything to anything else with Ethernet and MPI (e.g. LAM or MPICH implementation). I guess for Myrinet (=Gbit-Ethernet) you'd need PCI slots though, I'm not really familiar with that.
SMP saves
1) space (+ HW costs)
2) if you do it right (as in interweaving OpenMP and MPI, quite messy) it saves you latency and gets more bandwidth on communication between nodes. Nothing (as of now) beats the Cray communication technology, certainly not anything having to take the path MEM-> BUS -> PCI -> CABLE (including handshaking) -> PCI -> BUS -> MEM.
But notice, if you don't need heavy communication, clusters (w./ Ethernet) are fine, such as the NASA computational gravity stuff and cryptocracking e.g.. Other apps, like Lattice QCD (very communication intensive) will have to wait longer, until they get anything comparable to a Cray.
As for the def of SC: I don't know it, but the definition will be exactly where it matters (as you said): in the law. Anything else is just words, words, words.

In the latest episode of "As the karma burns", some 12 or more hours after "Hurrying to post this...." was posted someone apparently couldn't find anything worth moderating up anywhere and went after it instead.

Am I the only one that thought that this was from "Los Lobotomy" labs?
Or, better yet. Just buy their parts from Taiwan and avoid the US restrictions altogether.

Remember MS's NT clustering software was called "Wolfpack?" Probably unintentional, but an interesting coincidence.
Hmm, you might want to go hear Los Lobos before you trash e'm. I saw them less than a month ago, and it was a great show.
but everything else they've ever done sucks.
I'd like to see your list of everyting else, unless (and this is my guess) those are the only songs you've ever heard.

Are you smoking crack? Los Lobos, the band, rules! The La Bamba soundtrack is the least of their efforts. They only did like three tracks on that one. Their real albums like Will the Wolf Survive and By the Light of the Moon are American classics. They've all but disbanded now, with getting old and the recent tragic murder of Cesar Rosas' (the guitar player) sister. But in their prime, they had total street and star cred. They were pack-the-house headliners and everyone from The Grateful Dead to Bruce Sprinsteen to Sonic Youth wanted them as openers. They rock!

Athlon motherboards are already incompatible with Intel processors. The Athlon core just can't do SMP right now, nor does AMD have a SMP chipset.

Oh yeah I'd like about a dozen 486's sitting around needing tons of space and power. Meanwhile a dual pIII would kill it. Don't forget the cost of gigabit ethernet and switches. Fast ethernet is still no match for craylink or ccNUMA which averages around 600-700meg/sec, and under ideal conditions gigabit is still 120meg/sec. It might be good for cracking seti blocks but moving around tons of data no way.

Hehehe, I thought it was an obscure reference to Short Circuit II, where there was a gang called Los Lobos. Y'know, "Los Lobos kick your ass, Los Lobos kick your face, Los Lobos kick your balls into outer space!".... Still, it just means "The Wolves" so it would be pretty common. Especially reasonable since some people wer saying that its the school team name.
My Beowulf DVD (see also here).
I've been mulling this over for the last couple weeks, ever since I dug through everything I could find online about the Beowulf linux project. Clustering looks like something that's going to revolutionize computing, but wouldn't it be truly interesting if we could find a way to cluster dissimilar equipment efficiently? An office could take all of their old equipment, 486's Pentium's Pentium II's, and throw them all in one gigantic cluster to harness the power of all the obsolete silicon. If this is an impossible dream someone PLEASE wake me up...
Just for the record, the UNM mascot is the Lobo. Everything here is `Lobo this' and `Lobo that'.
The UNM sports teams are The Lobos, which is Los Lobos in Spanish. New Mexico has a large Hispanic population so they were just trying to fit in.

But the band was the first thing I thought of too and I live here.
It's amusing to note that Macintosh touted it's G4 multi-processor workstations as violating export restrictions by being considered a 'super-computer'. But it just goes to show how out of date US export law is. Besides, what's to prevent someone from buying a 250 port switch from Cisco, 250 workstations from IBM, and then shipping them seperately and downloading the Beowulf software seperately?
Export restrictions aren't very restrictive, taken in that light. National security most certainly isn't being enhanced any...
AMD's processers can do multiprocessing (or could, I vaguely recall a rumor they dropped this with Athlon). The problem is that all the MP motherboards use Intel chipsets which support Intel's style of MP. AMD (and Cyrix et al?) don't have licenses to the Intel MP technology, and came up with their own -- which requires a different mobo chipset, which nobody makes because the boards would be incompatible with Intel CPUs.
With AMD's recent growth and giving Intel a run for its money on releasing faster CPUs, we may see that change.
Oh, and a Beowulf is clustered, so doesn't care what manufacturer makes the CPUs, it can even mix them. It's tightly coupled SMP machines that care.
-- Alastair
If I remember correctly, somebody took 50-75 AIX RS/6ks and clustered them a year or two ago, with pretty nice results... Of course, you could always just get an RS/6000 S80 or a Sun e10000... or go all the way to a mainframe (I'd still love to have one, though a Cray-1 with the couch would be even better...)

Wouldn't it be great if this really was a whole new story about a whole new Netfinity cluster at UNM? Then they could Beowulf the two clusters together into one of the top ten supercomputers.
Oh well, just thought I'd mention thought before this thread gets wiped.

You can cluster AMD right now! One processor per node, but then again the Intel solutions don't ramp above two/node.
Ah yes, the practical difference between a Beowulf and a supercomputer! Dig in your pocket and pull out some coins. Nickels are commodity clusters, pennies are SGI boxes and dimes are Cray. They are a collection of the same thing, namely coins/supercomputers. But what differentiates a cluster from a Cray? The intended purpose of the components. All the bits of a T3E were designed for it. In a cluster, the parts were designed for (and in most cases are) low cost workstations, hack rigged in software to run as one monster machine.

Stop trolling. Linux isn't touching solaris in the data center market. It doesn't touch it in the scalability department, and the x86 hardware to run it isn't there even if it could.
If Linux is just killing Sun then why can't they stop making money hand over fist ? The fact of the matter is that Linux scalability plain sucks, and the answer has been "we're working on that" for at least 2 years. It _is_ getting better, but it is simply not up to par with OSes designed explicitly to handle the massive multi-cpu systems made by their vendors.
Finally, "Beowulf != Scalable". Last time i looked into it, beowulf was originally very much like an MPP and had made some inroads to providing functionality of single-image computing. The applications of linux's "clustering" are still quite narrow, and chances are most people that say they want beowulf clusters don't have any clue what they'd do with them.
Scalability for most people is something different. "Hey, i've got this webserver and RDBMS that are both thread-aware and thus can benefit from SMP machines..I'll just add more CPUs and RAM to this giant box and they'll automagically get better". Linux is an extremely poor choice for that scenario. The kernel locking is still much too coarse, too many sections are still non-reentrant, and the SMP hardware linux supports isn't particuarly scalable anyhow. Linux is _so_ poor a choice for true SMP computing that that was the area that made those amusing Mindcraft comparisions between Linux and NT realistic (i.e. NOT falsified). If you bother to look, the comparisons were using Multiple CPU boxes with Multiple Network cards. It shouldn't surprise anyone that NT did much better here, as at that time (and perhaps even still today) the linux IP stack was not re-entrant. The test took advantage of the fact that NT handled multiple device instances and SMP extremely well and Linux handled it extremely poorly. NT was designed for SMP from the ground up, with linux its been a progressive hack.
People who disagree are more then welcome to come up with facts---NOT trolls, to support their arguments. Postings which make unsubstantiated claims and predictions are basically useless.
My opinions are my own, and do not necessarily represent those of my employer.
When is AMD going to get off there arses and make their processors friendly to the whole multiprocessor shindig? Translation, when do we get Athlon in a beowolf or SMP? If AMD is serious about wanting to compete with Intel than they need to start working on proof of concept projects like this. Second question is what is going to be the practical difference between a supercomputer and a beowolf cluster. They are both starting to be made more and more like each other. More to the point, how do you define a supercomputer? This is very important for things like export controls.

I suppose now someone's going to ask if it runs Linux... At least it's already clustered, so that throws that question out...
I don't like fish. Reverse the fish to e-mail.
Take a look at www.scali.com They provide high performance for beowulf clusters based on linux. They have really some impressive stuff running on their test clusters. It seems that they are getting close to linear scalability of informix. Add a node and the performance increases ~linear.
Why name a supercomputer after a second rate band? I mean, yes, the soundtrack to La Bamba and Desperado, but everything else they've ever done sucks.

As long as the computer plays that cool guitar intro from Desperado when it boots, I guess it's okay.

The athlon is SMP capable, there's just not a cheap commerical memory controller that implements it yet. It's the same bus, same SMP structure as the Alphas, and they have done it, but AMD isn't producing chipsets (you'll have to ask VIA).
