TeraGrid Gets an Upgrade
The Fun Guy writes to tell us The NSF has awarded $48 million to the University of Chicago to operate and expand TeraGrid over the next five years. TeraGrid is 'a national-scale system of interconnected computers that scientists and engineers are using to solve some of their most challenging problems. TeraGrid is the world's largest open computer, storage and networking system. Only the U.S. Department of Energy's weapons laboratories have larger systems, which are dedicated to classified research.' Currently, the TeraGrid's power is just over 60 teraflops.
Does it run Linux? Oh, I see it does... nevermind.
the first thing that went through my head
was how do i get access and how fast can it crack
a hash.
stupid i know, but what fun to try it.
I like it - maybe they can define PI down to an even greater degree. !!
...stack against the likes of distributed.net and other similar projects for processing power?
Unpleasantries.
but only if it comes in white....
When the posters fear their moderators, there is tyranny; when the moderators fears the posters, there is liberty.

Replace "challenging" with "Parralell"
Wow, sent an e-mail as suggested when clicking on "use classic" banner, and got a fast response that addressed my msg
A beowulf cluster of these!
A good slashdotting should be just what they want to test their servers.
Replace "challenging" with "Parralell"
Replace "parralell" with "parallel"I wonder when the cluster discovers it's own existance and deticates that there is no need for the human race.
...Windows Vista!!
Had to say it, sorry!
please excuse my apathy
...giving a whole new meaning to Teraflops.
"Made up/misattributed quote that makes me look smart. I am on
... until I make that system my personal zombie!
hah .. you could just put 60 xbox 360s together to achieve that kind of power ..
xbox 360 specs
And so, without further ado:

...you know, developing sources of energy.
it makes me smile.
... cool.
... the people of Slashdot!)
It's just so
(And the only people who I say that to are my research group members and
The TeraGrid is well managed too.. very few problems for such a huge system.
Favorite
... that some of that money is going to go towards securing the system. :-\
This will only take one reactor core to power, but Vista's specs say it will require a dual-core system, minimum.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
A Beowulf cluster of those!
Oh, wait...
C17H21NO4
The next generation of FPS!
DYWYPI?
I bet it was still cheaper than 30 ps3's
There are other problems where this is just out of the question... Tightly coupled problems just cannot be run efficiently even on clusters of workstations(COWs).
If I can grab you attention for just a sec: Do you know of any books [or treatises or papers] that deal with the question of whether [some given class of] problems might be provably non-parallelizable?
Heck, if you could just give me a few keywords to Google, I'd be really grateful.
Thanks.
The NSA certainly doesn't have computers anywhere near this. No siree.
Note to mods: I'm probably being sarcastic.
How does this compare to the acres of systems at NSA, NRO/NIMA, CIA, and DIA?
The xbox 360 is going to use a Cell processor. The cell processor it is going to use is capable of 256GFLOPs single-precision and 25GFLOPs double-precision.
Double-precision is all that matters in most scientific apps.
25*60 = 1500GFLOPs = 1.5TFLOPs
You'd need 2400 xbox360s to get to 60 TFLOPs.
Also, Xbox360s have 512MB of RAM. This would not make for a very useful cluster node.
Other things like large matrix multiplications or FFTs or N-body problems do not scale as well. In these cases as you subdivide the problem into smaller pieces for your larger number of machines, the computation on each processor will quickly become small while the communication between processors will become more significant.
But has anyone attempted to create a systematic [or systematizable] framework within which you might be able to prove that a certain problem was necessarily non-parallelizable?
Cf Lagrange/Abel/Galois et al proving the non-existence of solution algorithms for fifth-order equations.
Or Turing proving the non-existence of halting algorithms.
Wasnt there a movie about a computer like this? Get it up to about 100 terraflops and then throw in a little AI and next thing you know, it will only talk to you if you call it cybernet...
This round of Teragrid funding is $150 Million. PSC got $52 Million. The rest is split up among the other 7 institutions. The other major partners already got big awards under earlier rounds of funding.
Oh, and this news is a month old.
I understand It's 'powerful'... but... will it run Half-Life 2: Lost Cost?
I looked on their site and I can't see anything about getting an account (except for a form to fill-out to add users to an existing account)?

Is it kind of wierd that in
# define USHRT_MAX 65535
and the number of processors on that thing is 65536 (add a 0th processor). Anyone who knows about HPC systems care to elaborate how that happened?
The TeraGrids have already won.
USHRT_MAX has to be one less than a power of two on any system that uses binary integers (i.e., on just about any system in the real world); 65535 is the minimum allowed value. It's not a significant limitation; if you need bigger numbers, use a bigger type.
For various reasons, the number of nodes in a system is often conveniently some power of 2.
The fact that USHRT_MAX+1 and the number of nodes in the BlueGene/L system happen to be the same power of 2 is purely coincidental. It's conceivable, I suppose, that something is using a variable of type short as a node index, but I doubt it.
Sombody make sure Cyberdyne systems was NOT one of the vendors involved......
In case you are wonder what the DOE needs teraflop weapons computers for...
think ICBM, baby... http://www.sandia.gov/media/online.htm
Sometimes the question "Does it run linux" is asked on a relevant subject, and is not funny, but just inquisitive. It becomes humor when it is used on totally unrelated subjects. It is the same way comedians make certain jokes, or put a theme in a show.
In this case the comment is perceived as funny, on the next it can be perceived as redundant, troll or overrated.

And you'd then be completely screwed as a serious security door will have deadlocks to stop you doing just that!
Just don't fry the comms kit so someone outside can hopefully come and find you...

Hmmm, TerraGrid... can anyone say 'SkyNet'?
