How to get 1.5 TeraFlops from Linux
Oak Ridge National
Lab has purchased from SGI an Altix
3000 (flash movie). This
article claims that:
SGI Altix 3000 is recognized as the first Linux cluster that scales up to 64 processors within each node and the first cluster ever to allow global shared memory access across nodes.

That was modded insightful? Hmm this'll probably be modded informative or something.
Or -1 troll. Which is, of course, most likely.
Hi, I'm interested in catching large catfish, I live in the Great Lakes region and wonder what kind of bait is best for catching the real monsters. Can you make any recommendations?
Dear gentle sir--
Like you, I have sought after the large, ancient cats that swim silently in the black, murky depths of our nation's beautiful Great Lakes. After spending years using liver, cheeseballs, nightcrawlers, mealworms, chicken heads, and fox urine, I can suggest a bait superior to all of these to aid in catching giant monster catfish. I have produced some record specimens using my home-grown technique and I now pass my secret on to you:
Kittens.
Yes sir, that's right. Baby cats. I find it most effective to use 1-5 day old kittens. They won't survive away from their mother at this point in their development anyway, so why not hook them on a weighted line and sink then to the bottom of Lake Superior in hopes of catching that 2-meter beast you dream of in your sleep?
I find that soaking the kitty in blood before hooking works best. Other scents to use are fox urine, hydrated bloodmeal (a blood substitute), rotted chicken liver, curdled milk, or rotten eggs. They can be doused in the scent material but keeping them flailing around in a cooler of the liquid around an hour before hooking them yields the best results. Don't fill the cooler up too high, however, or you'll drown the kitten. We need live bait so that the little kitty's struggles will attract our quarry.
Another trick I've found to make your kitten bait last longer is to take a plastic bag and a rubber band, placing the bag over the kitten's head. Use the rubber band to seal the bag around its neck. This simple trick increases the time the kitten lives after being hooked, weighted, and cast. Typically a kitten will drown before three or four minutes. Using a bag, I've reeled in live kittens after over 30 minutes crawling around blindly at the bottom of a lake! If you're lucky and your prey doesn't inhale the kitten entirely, you can release the bag and let the kitten have a breather before recasting him in. You get at least four times the mileage bagging your kittens' heads!
I hope you enjoy this technique. It will give you an edge up on competitions and will yield fantastic results. How ironic would it be to land the monster of your dreams using the animal it was named after for bait!
Happy angling!
I can't wait to run Staroffice on that thing. Those stuck on MS are sure to swtich now!
Who wants a Beowulf cluster gets a bitch slapping.
Though I am thinking a really big Quake server. Weren't there some maps in Quake 2 that could support 200 people at once? That's almost enough for MMRPG work. Hm....

And this one will probably be modded funny. Those moderators are chumps.
First, there was a plan: how to bring together the different development groups at work? My boss said there was a sort of tension he thought could be eased by some social interaction. Not easy. Almost all of the different development groups despised each other, each thinking its "art" was more important and eloquent than the others'.
There was the kernel extension developer group, coding mostly in C and some PowerPC and x86 assembler. They worked on making our PCI board work with Linux, *BSD, Mac OS X, QNX, and Solaris. They worked "special hours," coming in at one and staying late, supposedly, until seven or eight at night. They enjoyed Jizz cola and had a penchant for ThinkGeek t-shirts and cracking jokes about Win32 API calls and the dreaded Blue Screen of Death.
We had XML developers too. They worked on our website, documentation formatting, and simple apps to configure the driver software. They used HTML, XSL, JavaScript, and a bit of Java. They typically dressed casually, drank coffee and tea, and liked to work straight from the spec: no "Learn XSL in 30 Days" books were to be found in their cubicle farm.
Then we had the guys who wrote full-out UNIX apps. These guys and the products they wrote had been acquired from another company, and were the source of most of the tension: they'd never really been integrated into our group except that they were physically present with the rest of us. They all had beards or mullets or long, unwashed hair. Many wore suspenders or the afore-mentioned ThinkGeek clothes; some even had Penguin tatooes or small C app code tattooed on them. Their cubicle farm was known for the bleating laughter that exploded when one of them found a "silly" bug on someone else's code, and for the rotten, fetid stench that could only be compared to three-day-old shit reeking from inside a rotting corpse's abdominal cavity.
So, in order to get the guys to "know each other" my boss had asked me to organize a during-hours, alcohol-friendly party. My ideas ranged from a keg or two to live entertainment, AKA strippers. But as to what to get them to actually talk to each other in a human manner I had no clue. So I let it go til the last minute and decided to let my inherent creativity mull it over in the back of my head.
When the day of the party had arrived, the catering company brought in a few trays of lunch meat, chicken, pizza, and side dishes, I had picked up the kegs (all four) from the local brewery, and the big-screen TV and DVD were set up ready to blast the Matrix into the eyes and ears of my co-workers. The eagerness in the the air was encouraging and I thought that loosening up and smiles going on even now were a good sign. I even saw some of the guys who'd known each other previously begin to bunch up, bringing along the co-workers they knew from everyday work.
The first thing everyone did was hit the food line, loading up their plates and grabbing a cup for beer to wash it down with. A few approached me and thanked me for the food; it seems appeasing the belly really did tame the beast. After a few minutes of silence and eating and a few second and third courses, they guys were ready to sit down and be entertained. After asking if anyone needed anything else before the movie started, the lights went out and the Matrix began playing. I heard a few enthusiastic comments and jokes being told.
About half-way through the movie I noticed a lot of the guys, especially from the UNIX app group, were getting up and presumably going to the restroom. No suprise, as the second keg was history by now and the third was probably half-way gone. I also noticed some of the guys bumping into things and stumbling. Alcohol's the social lubricant, eh? Well, not long after, my bladder beckoned and I answered. As I made my way to the restroom, I had a self-satisfied smile on my face: my little plan was working, my boss would be happy, and it might even a Christmas bonus or a promotion (even if in title only).
Well, as soon as I pu

PVM's pretty good too, for explicit cluster programming. I've found it to have a better feel (from a programmer's point of view anyway) than MPI and there's Concurrent Haskell support for it in GHC6 too!
Of course, I could be wrong -- doubtlessly MPI has improved since I last tried it a few years ago.
I've never seen a "smart" compiler as you put it, though there are systems where the programmers can explicitely parallelize a loop.
Oh, because you've never seen it, it can't exist? Great logic there, I hate to think what your code is like. See here and here and here.
