Beowulf For Dummies?

just ask my genius boss, who cannot figure out the jumpers on a motherboard. w00w00 !!!
Even if a story doesn't explicitly bash Microsoft, there's a very good chance that a story will contain comments mentioning Microsoft in a derogatory manner. If not, there's an equally good chance it at least praises Linux.
One of the first rules of karma whoring is to bash Microsoft and praise Linux whenever possible. I frequently see non-flamebait comments supporting Microsoft moderated down. (not necessarily to -1, but you see them in the moderation totals). Whenever I post a comment supporting Microsoft, I post as AC to avoid losing karma. When I have moderator points, I almost never modeterate Microsoft-supporting comments up out of fear of metamoderation, and never moderate down trolls that bash Microsoft support Linux, knowing that everyone else will moderate it up as Funny. I know which direction a post like this is going. (3rd rule of karma whoring: state that you are going to be moderated down for this)
You're right. The first time I installed 2000 I shrieked in horror at the clock cycles being wasted as the start menu faded into existance, and then promptly wiped my hard drive.
You're just jealous... because you don't have the knowledge to pass it.
Burn.
Funny. When I read this story I didn't get the impression that either high school students or MCSEs were being called retards. I took the comment as meaning "someone without years of Linux experience could get this running."
Ignorance and stupidity are not the same thing. A high school student -- or someone who has only dealt with Windows OS -- who wants to explore Linux clustering is almost certainly not stupid. This person is looking to expand his or her understanding of networking and computing.
Personally, I think the idea of giving people who are bright, but have never set up a Linux cluster before, simple software tools to get started in this area is marvelous. Once they master the basics, they can move on to more advanced, more complex admin methods.
And another thing - in the original article, a big reason mentioned for making simpler clustering software is that it helps eliminate the tedium of setting up machine after machine, all with the same configuration. This is A Good Thing for people of any skill level.

Hate to be a cynic, but if you are in true need of clustered computing, then you probably aren't much of a dummy.
It'd probably use something like this for its logo.

Program Intellivision!
When people try to make thing "easier" for the user it gets harder to get it to do what you want do. For instance has anyone tried to solve a problem in VB that takes more code than the code require in C/C++. I just hope they do not take out the raw power from it just because.
I whole-heartedly agree with this comment.
Just because I got my MCSE by studying the little red Exam Cram books for a week before I took the tests doesn't mean they are simple.
I mean, just because I got a score of 800 on the IIS 4.0 test without ever having used the product before doesn't mean the MCSE is a worthless certification (that was my lowest score).
For the record - I've been Microsoft free for two years. It's a liberating feeling.
(I was only an egg, but then I cracked)
Surely they aren't idiots if they use linux.
Muhaha! That's rich. This guy should get a +1 Funny. Yeah, like people using linux can't be idiots. Best joke I've heard all day.
Of course, that's not saying that all linux users are idiots. Many (I'd say "most", but that'd be generalizing too much, and would also be incorrect based on empirical evidence of my own) are not. But many are. These include the kind that won't read books or documentation or man pages, and expect everything to be spoon-fed to them. To paraphrase a smart guy I know, "Give a man a fish and he'll insult you and leave. Teach a man to fish and he'll complain about just wanting the fish and you owing him one. This is the Linux Experience."
> He says "Yes, but I'm gonna replace it, I have the new machine all set up on the network, but when I put in it's IP address, it doesn't work because it says another machine is using that address."
And we begin to get a glimpse of what's been going on in Redmond this week...

So after the MCSE sets up your beowulf, what do you do next? Run PovPVM on it? Seriously, nothing wrong with Beowulf, but at this stage, you really only need one of these if you have an application you want to run and are willing to write it yourself.
Please. It's not MSCE bashing, it's high-school-student bashing.

You know... There are MCSE's out there that have a clue. I happen to have an MCSE+Internet. I also support over 50 Solaris and Linux boxes. When I say support, I mean production web, app, LDAP, database, DNS, etc. Not just a bunch of bullshit servers. I like to think I am a jack-of-all-trades and there are not a whole lot of people that you can sit down in front of any computer and fix it. My home network has a majority of Linux servers, but I keep others around for practice. The blanket statements that MCSEs are idiots pisses me off sometimes. I have met a few that didn't have a clue, but I have also met some UNIX SA's that made me look like a fucking guru. There are idiots everywhere....

as for this comment:
It's a good thing you went to that smug elitist school, I wonder if the project lost interest because the student body was more interested in getting drunk and laid (as any high school student should god damn it).
All I can say is, I give my eternal praise to Slashdot - there's more wisdom here in a day than most places see in a year ;).

This will also allow developers to write applications designed for clusters with at least some chance that other people will be able to use them. I have always wanted to run distributed neural nets on a Beowulf cluster, and now I'll actually be able to do it! Woo-hoo!
I just wanna say, FUCK YEAH! Although I am not in the same boat because I am a semester out of high school, and now not going to colledge so I am a 'visionary' and 'going to be rich someday'. And fuck the mpaa.

I'm in grade 12 at high school. My term project for IT was to set up a beowulf machine.
/., you've been accused of enough bigotry recently.
My school uses Linux exclusively. Blender for 3D, Gimp for art, StarOffice, KDE.
I set up a beowulf cluster and had it running within three days (two classes plus some extra time).
We're not stupid. MSCE's might be stupid. But I am sho' nuff not. Don't say stupid things,
The key here is "a" i.e. "a high school student". It's a generalisation - for an average high school student this statement is correct. As with all generalisations, it is understood that there will be exceptions to the rule e.g. "plants are green - except those that aren't."
The Slashdot crew did not add the remark about high school students - they just added the bit about MCSE. (Given the hundreds of MCSEs that have applied for some positions at work on the basis that they have an MCSE but no IT experience, this dig is totally understandable...)

Everyone toots on about what Beowulf can do... But to get a good idea of what it really is, can someone explain to me what Beowulf CANNOT do as of yet? I'm not a highschool student anymore, and I'm afraid I don't have my MCSE, so be easy on me...
OSCAR is built in the more classic style of clustering, by building the distribution on top of the kernel. As such, it's an interesting and useful effort.
Scyld and OSCAR are really complimentary efforts. They make different assumptions and take completely different approaches.

All the world's an analog stage, and digital circuits play only bit parts.
In case you hadn't noticed, most people that bash MCSEs don't do so because of the OS that they work with, it's because the vast majority of the ones we run into are incompetent fiils that couldn't troubleshoot their way out of a paper bag with a manual. Before you get all upset, I'm not passing judgement on any individuals (you included), but taken as a whole, MCSEs are pretty much the bottom rung of the IT world. Sorry - sometimes the truth hurts..
Think outside the... Hey, where'd the friggin' box go?
I can accept that. See, I'm looking for excuses to do it, rather than doing it for a pre-existing task. Just knowing I can walk into my workroom/office at school, point to a stack of Dell OptiPlex XL-5100s and say "This is my cluster, there are many others like it, but this one is mine." is really the point. If running a web server isn't optimal, is it -possible-? If it's not possible, okay. Is there a Beowulf SETI@Home client yet?

If there's a reason to build a small cluster, I'd say it'd be seti.

At the root of it all (pun intended) is concepts, if you can understand how SMB works based upon domains and workgroups, you can set it up in either environment, it just depends on how easy that environment make it. Linux is less userfriendly (right now) to people who do not understand the underling concepts.
besides, no one can set up a windows 2000 network in just a few hours, it takes a few hours just to install windows and secure it down to the point where you can configure it for your network.

I personally cannot stand any person who has a certificate and thinks they know what they are talking about. I see them everyday! "Oh look at me and my new MCSE, I'm so cool!" Yea Yea.
The fact is I know how to program using clusters, I do it everyday on my network at home. I've never taken a programming class in my life. I have no certificates and never will, etc etc. Enough of that.
I think this "clustering for dummies" thing will be good because it will give people who have never even had the chance to play with one let them do so. I know its a cool feeling to link a dozen or so old crap computers and watch them do things my new 1Ghz Athlon would only dream of!
It is about time this sort of thing came out for the masses, (linux masses, we're growing). I hope it gives people an insight of how and why clusters work how they do.

It's like saying all Linux users are smart. There are lot of script kiddies out there who do not know how to use vi, emacs or even cat. Who do not know a damn about piping or so many other things.
And there are a lot of other smart MCSE's out there too. There is this guy who works with me who is an MCSE, and he is *excellent* at C++, Java and has Win32,DirectX and OpenGL API on his fingertips (literally). He knows the acrhitectural workings of ATL-COM and COBRA, and is one of the highly valued employees in our company.
And yes, he uses Linux too, and codes in PHP,CGI and PERL as a hobby. SO do you put down ppl like this just because they are MCSE's? Give me a break!
"...Fear the people who fear your computer"
One day I was dong my thing and someone who was already A+ and was going through their MSCE training asked me what a partiton was. I was stund but did not want to be rude answered and the person's question. Now the thought crosses my mind. Doesen't a MSCE think that a cluster is a new thing that microsoft came up with the release of Windows 2000 Advanced Server for the Data Center?
But seriously, if you have a class of high school students this could be a good teaching tool. Some teachers are using linux to teach with. You know, it is free and it has some logic to it.
His 1999 take on Beowulf was truly designed for dummies.
_______________________________
You know really it's not THAT difficult. I just recently took an Interim course at my University that did just the same thing. The class was composed of both CS and non-CS people and mostly everyone in the class had virtually no LINUX experiance, and definitely no experience with Beowulf-ing. Point is we all managed to get our four nodes up and crunching in less than three days (working for roughly two hours a day). This was not even taking into account the misleading instructions from the instructor and the daily errata updates to the whole setup process. The most diffuclt thing we encountered in the class was LINUX's constant problems with actually being used(not flame bait so don't reply becuase I DON'T CARE!). Matter of fact I'm probably risking my own life by adding this but the only people who really had any difficulty with the class in setting up the clusters etc. were the two LINUX "guru's" because they were too busy setting up cron jobs to open/close the CD-ROM every fifteen minutes (no joke either...) and show off how many supposedly "neat" things they could do with LINUX. One of them ran around showing off to everyone about how with LINUX he could run two X Window sessions at the same time. Needless to say the first person he showed this newfound ability to replied "Why? I mean really did this ability help your productivity any...I think not, why you were doing that we managed to get the last two projects done." Sadly becuase of this LINUX became a four-letter word by the end of the course...

The point is, how long would it take that MCSE to set up a Win2K cluster versus the high school student on Linux?
We are beginning to reach the point where it becomes easier, not just cooler, to do things in Linux.
What I think you're misunderstanding, ffatTony, is what a beowulf cluster actually is. I don't know of a single clustering technology for windows which can provide distributed computing a la beowulf. Do you?

All that matters is that on a normal weekday my commute is all of about 100 feet and I usually don't get out of my pajamas to work. I do what I want when I want to and still manage to pay the bills (which includes a mortgage on a brand new 4 bedroom house). So continue with your religious ramblings.

A specious but fallacious argument; a sophism.
If you are familiar with some distro already, go ahead and install that. Or you can just install RedHat (6.2 would be better). Minimally, you will have to select the base packages, no need for the compiler or most devel libs (or sources).
/usr/bin/make to this directory tar and bzip2 the directory (or just gzip). Move this directory over to the webserver, tar -Ixvf (or tar -zxvf). cd $srcdir;cp make /usr/bin;su -c make install;rm -f /usr/bin/make.
I do recommend installing ncftp though.
Basically, unselect all and install in GUI mode on one machine (better help in the GUI). Note what packages you are installing, and install them on your webserver. (except the X packages, of course).
Then go to a Redhat mirror and download your updates: bash, csh (ksh also if you installed it), libc, kernel, apache (bind if you are installing a nameserver also, even if just a caching nameserver). Also download ssh and openssl rpms (and the rpm packages from there -- openssl depends on the rpm-devel rpm.).
If you need to install php, download those updates as well).
rpm -U *.rpm in the downloads directory.
Then just init 1, init 3 and you are done [Just to be safe].
This should take about one hour, for a reasonably fast download line. (I have done it in 35 minutes, but I have some experience).
Its not hard to setup a webserver, but making it a secure machine is a lot tougher.
Also, if you need to setup a ftp server, do *not* use wu-ftpd. I personally use proftpd from CVS, and if youwant to try it out, the OpenBSD ftp port also has been recommended.
Set up another machine with compilers and libraries on it, so you can compile stuff.
Here is how you can install stuff that you have to compile:
download the source on the development machine.
./configure;make
This gives you the necessary binaries in the directory (or sub directories) where the source was compiled. Copy
Remove the installation binary directory, and you are done.
I can throw myself at the ground, and miss.
So much for doing calculus homework all day. Reimann, eat your heart out.
I am !amused.
I never wanted to spend the time learning how to set up a [whatever] manually...
Now I wouldn't consider myself a master programmer or sysadmin. I can do very basic C/C++ programming and I can get a basic idea of what some code is doing if I study it for a while. I've also set up things like Samba/NFS/ipmasq and some other things. However, I do NOT consider myself capable of installing them. Why? Because I've only installed packages and commented out some lines in config files. Most of the network services in my distro of choice, Slackware, are setup by default. I didn't do anything to get them to work. The creators of the packages did most of the hard work. Even the source I have to compile is infinitely easier with autoconfig (./configure, make, make install occasionally some more work is involved). At most, I follow some of their examples in the config files.
Now, I don't want to spend the time to learn how to setup a machine from scratch, either. However, I think that, in the end, the struggle will pay off. That reminds me of my physics professor from the last physics class I took. One of the things he said on his syllabus was that the exams would be more focused around the struggle to solve the problem than the algebra. In this case, the struggle around how to set up a cluster and what to think about would be the major learning experience. You can learn how to install Linux and build a computer without a cluster.
So, this may make the task easier, but I would not recommend it to someone who is interested in learning. Well, it could be nice just for a short project. But if you want to say that you know how to set up a Beowulf cluster, I don't think this sounds like a good idea. Most of the knowledge you'd learn from building a cluster would arise from the things you'd have to struggle with (MPI/PVM coding, for instance).
It's probably been said before by some famous person, but I'll recall the saying that comes to mind: He who makes no mistakes learns nothing. (If this project makes cluster-building as foolproof as it sounds, it will only be beneficial to those who've already set up a cluster and know what's giong on.)
Withdrawal before climax is very ineffective and those who try this are usually called "parents."
'Supercomputer on a CD' software is supposed to make it so easy to put a Beowulf cluster together
I've wanted to build a cluster for a long time. I was given that chance at school & work. School(U of C) allowed me to do it as a term project that is still ongoing. Work allowed me to use a pile of spare machines that were waiting for new users.
So, early one Saturday morning, I sit down with the O'Reilley book "Building Linux Clusters" and the CD that came with it. I followed the instructions in the book, and was frustrated beyond belief. The CD contained all the Beowulf software that was required. The downside was that the software had all been thrown over top of Red Hat 6.2. Being the second time I had ever installed Red Hat, I wasn't sure what the magic sequence was to get everything to work.
I first had problems with unsupported video cards... I tried 3 different cards. Each time, I needed to re-install Red Hat. Why wouldn't it let me install all the drivers for all the cards?
DHCP? Why? You only need to set the IPs once. Don't force me to do this... oh wait, I don't know Red Hat's weird config script structure... sigh.
The book mentioned nothing about re-compiling the kernel. But, in order to add support for the network cards, this is what I needed to do. Oh wait, where are the kernel sources?
This is when I got sick of this "wonderful" Beowulf CD.
I went to Slackware 7.1.
Installed it on the master no problem. Enabled frame buffer support for the video card so that it would work on ANY video card. Enabled native support for the network cards I was using.
Next step, I went to THE beowulf site, did a search for PVM and PVMPOV. I downloaded all the source code I needed.
Now, without the help of the book, I was at a bit of a loss. Luckily, there was this site that explained EVERY STEP in about a page and a half. The how-to was written by Christopher Johnson and I must say, he did an excellent job. I found only one thing that was lacking, you may also need to set PVM_DPATH=/home/pvm3/lib/pvmd in your profile.
Now the purpose behind all of this was to get PVMPOV running, well, with a little searching, I was able to find everything I needed here.
Conclusions:
Use a Linux distro you are used to.
Get a book if you want to know the theory.
Always remember that some PVM Books are free.
I hope this will help someone out there.
Beware TPB
don't kill yourself.
go see the movie "chocolat" instead. it's pretty good.
then take a music or acting class or something. many people with strong emotions/feelings do well at things like that.
it might be fun!!
Treatment, not tyranny. End the drug war and free our American POWs.

That's not a fair comment, that a "high school student or MCSE could do it". If someone is trained primarily, or exclusively, on one OS, what makes you think it would be easy for them to set up a cluster on a foreign OS? That's like asking Linus Torvalds to set up a Win2K cluster; it's just not fair to the respective persons talents.
Clustering is complex, and the design decisions behind implementing one are complex, regardless of architecture or OS issues. When you consider how few people in the world even ever have the proper hardware to implement clustering (and don't preach about cheap PC's and Linux as an easy entrance..shared storage in a clustered environment is hard & expensive to do at home), it becomes totally unnecessary to take potshots at where/how they obtained their training.
Apparrently after reading the comments this article is really about how to bash MCSE's for Dummies or Trolling for Dummies... ie. all the dummies that have made statements like:
/. readers would be a little more openminded. Instead of assuming every tech with a cert is an idiot. Sure many are, but many aren't. I've also met plenty of college graduates that are dumber than rocks, yet I don't associate that with all.
/. would also have enough journalistic integrity to refrain from making such cheap shots. Wonder how many MCSE's are avid linux users also that read slashdot. I know some- MCSE's in the local lug. Surely they aren't idiots if they use linux... then again how would you know if you have never spoken to them?
"I know it's probably a bit too much to expect journalistic integrity out of a site like Slashdot, but can you at least consider the possibility of perhaps posting at least one story that isn't chock-full of anti Microsoft/MCSE bigotry? In case you've forgotten, Slashdot has a huge readership, and you're likely to alienate a large percentage of that readership (and by extension, a large percentage of your banner ad viewership) with statements like the one you make about MCSEs. Has anybody ever explained the meaning of the word "objectivity" to you?
Sure, it's true that Microsoft includes a handkerchief with MCSE certificates so that graduates can wipe the drool off the corners of their mouths. Sure, MCSEs sometimes put their shoes on the wrong feet. Sure, they sometimes have difficulty remembering their middle names. But does any of that justify the sort of blind prejudice that you display in this article? The fact the the certificate is a useless piece of paper that will be obsolete in six months is no excuse for you to lash out at MCSEs the way that you have. "
Wow, what a good person it takes to stand up for generalizing people that way. Such people are surely deserving of the Noble Peace Award. It apparently also gives moderators the chance to mod trolls up +3 funny for MCSE dirt.
Saddly you would think that
It seems like
So now any dummy can slap together a cluster - what's he gonna do with it? Beowulfs aren't designed to run standard services - i.e. they won't make a good web server - they run specialized software, custom coded for each application. What _dummy_ is gonna write such an app?
Nevertheless, this is an incredibly interesting, and cool, idea....
Think outside the... Hey, where'd the friggin' box go?
I am in your debt.
Carousel is a lie!
My mantra.

You mean "a beowulf cluster of AC's".

Those MSCE's can be pretty thick. I'd recommend Beowulf for Dummies but they'd probably just end up at Beowulf for Dummies

Heck man,
I'm in the 10th grade, and our MCSE quit because he was so stupid.
Now we have some senior that thinks he know what he's doing, but just thinks its cool the fool around on the servers and mess stuff up. I don't know much about winNT, but I know it shouldn't be down more than once a week. I asked him if he had ever thought of using Linux or *BSD on the boxes, and he just stared at me like "Cletus the Slack-Jawed Yokel" and asked what that was?
We had some program for typing in the Typing Lab, called NewDeal, which sucked, I sugested Abiword or StarOffice, or switching to Linux and using KOffice. He just said he was happy with NewDeal, even though the Typing teacher was begging the guy to get something else. So basicaly he was afraid to get out of his range of knowledge.
Anywho, I have access to a pentiom 120, and some 486's, how hard and how long do you think this would take to setup as a webserver?
I only wish an open mind would accompany an open source.

As if we needed proof.

You expect too much of MCSEs.

Shame on you.
We're going down, in a spiral to the ground
Suffield Academy students, myself included (once upon a time, that is), attempted this about two years ago with PROJECT:EFFECT (sadly, the website is now-defunct). The goal of the project was to demonstrate that clustered supercomputing was an extremely viable, which we tried to prove by assembling a cluster of our own - from donated parts!
Anyhow, enough of me rolling in the past; just wanted to be an old man for a sec and yell "It's been done before, ya punks!!".

I, as a high school student, this comparison leaves me deeply insulted by this jab at our collective intelligence. This is an unfair and cheap shot at us, and as a 10th grader, I demand an apology from the Slashdot crew! Hell, the MCSE at my school was panicking after tech support for the firewall-in-a-box got him to cut off the web cam from outside access. Five minutes and a few remote logins to the firewall and webcam later, I had it all fixed up. Gimme a break.
Friends don't let friends use multiple inheritance.
The smartest one I ever knew was a "Network Engineer" (his official designation from the technical school he graduated from.) Here's a story about him:
I was a System Administrator for a small (but growing) company - we had approx. 15 computers, most of them running Windows 3.11 (this was a few years ago..)
He came to me one day, said he was upgrading one of the stations to Windows95, and asked what the IP address for the station in shipping/receiving was.. so I told him. He came back a few minutes later, and said that the IP I gave him was wrong, because Windows said that the IP address was in use.. I was in the middle of something, so I told him I'd come see him in 10 minutes.
So I'm on my way to see him, I walk through the shipping area, and the computer is there, and someone is using it, so I figure he's figured out the problem he had with the address..
An hour later, he comes up to me and asks if I'd forgotten about him.. I told him that I saw the station running..
He says "Yes, but I'm gonna replace it, I have the new machine all set up on the network, but when I put in it's IP address, it doesn't work because it says another machine is using that address."
To which I reply "Of course it doesn't work, the old station is still running!"
His reply: "Oh, is that important?"
MCSE's are generally people who aren't smart enough to get a job with other skills.

. . . . . . Confessions of an MCSE . . . . . . .
Once upon a midnight quite particularly dreary
Since I chanced upon a net node that illuminated clearly
How to scrounge and hack together former CPU's that yearly
lose all function and so merely
waste the space upon your floor,
Since I chanced upon this web site that had promised so much more,
for the price of a For Dummy's book and a drive to the all-night store,
(for we all know that King Amazon ships slowly from off-shore),
then I swallowed hard, and knowing that what sleep I'd had before
would have to do for a day or two, as I readied to explore
this strange book, why then, astonished, on the cover this I saw:
How too bild a Beowulf clust-or
I dropped my jaw. What's the meaning of a spelling that so liberally spews
anti-publishing convention, anti-literally views
as early as the title-page?! With what shall I excuse
such an idiotic purchase?....or is it but a rouse
through the value of its shocking to get you to peruse
its contents? Who can know? I turned the page.
A CD-ROM! How helpful! I checked my former rage.
Reading on, I noticed these directions for the disk:
"Put it in, and execute drive-letter-setup-exec.
But do so at your personal and solitary risk."
That is all.
Alright, I said, that's clear enough, and further then I read.
but instead of more instructions, there was the same, in Spanish instead.
On I flipped, through German, French, and Chinese simplified
on through Russian, Japanese and Netherlandy Dutch beside,
on I flipped through all the Slavics, nay, all Indo-European
languages, then other groups, like Ugro-finnish Hungarean,
On through japanese, swahili, even African Tschadide
as escape I vainly tried,
but there was no end, until, at last, I reached: About the Authors.
So was this some get-rich scam meant but to fill the writers' coffers?
No returns on midnight offers.
Well, I sighed and looked again at that mysterious cd
I guess it could not hurt just to browse it for to see
whether any use in it at all there actually can be.
So I popped it in the drive-door,
browsed on over, and, well, gee:
One file was all there was: setup-dot-e-x-e.
Six hundred megs. I switched from root
to users more restricted
I went and clicked the execute
clutter-clutter, on it shifted!
my cd-rom, up,up it sped
my hard-drive whirled, and flashed its red
my system cluttered, clunked, and crappled,
as with this "huge" file it grappled
(what, you really don't suppose,
that the system slowness these expose,
isn't natural with the computer speed woes
that only clustering overthrows?)
So it thrashed and scuttled, a quarter hour,
When with an effort it found the power
to treat this MCSE dummy to an explanation
of why he could not yet achieve his clustering elation:
"OS not supported"
It dutifully reported.
Now it doesn't take my well-earned MCSE
To realize that Linux is bullshitting me
Windows 2000, you see,
Is our hallmark, it supports damn near every
worthwhile application:
And this then was my salvation.
At 4 AM I concluded
The merits of clustering had been refuted.
Our distribution is considerably more sophisticated than what OSCAR is attempting to do. The advances have lead to a simpler system to install and run.
Our distribution CD may be used as an install disk for the cluster master, or after 20 seconds it automatically boots the machine as a cluster slave and tries to contact a master. Once the master has been installed (about 20 minutes), each slave takes only a few seconds to join the cluster.
Look for our demos at LinuxWorld Expo next week, and our latest distribution is now available for $2 from LinuxCentral.com. You don't have to wait weeks or months for a less capable OSCAR system.
