New Apple Super Computer (Army)

[MacRumors]

Based on the success of Virginia Tech's PowerMac G5 supercomputer, CNet reports that Colsa has placed an order with Apple for a number of servers:

A U.S. Army contractor has purchased a $5.8 million, 1,566-server supercomputer from Apple Computer, a real-world cousin to an academic system that briefly appeared high on a list of the most powerful machines.

The new cluster is expected to reach 15 teraflops when it is completed this fall and will run Army simulations of the aerodynamics of flight.

Good news Apple

This was rumored a while back from some foreign web site and everyone dismissed it. Anyone remember the link?

Woohoo! Another one chalked up for Apple... how long will it be before we all have 50 Xserves in our basements?

MacCentral says it will be more than 15 TF.

Either way.....AWESOME.

I know twice as many xServes would scale directly to twice as much power, but just imagine if the 5.8 million dollars they used to buy all of these xServes was 58 million. Imagine Macs comprising the fastest computer in the world......still many times less than the 350 million dollar Earth Simulator!

25 teraflops ... that's blazing crazy fast. Go Army.

Well this isn't foreign, it is just AppleInsider :

Argonne National Lab, the National Security Agency, and NASA, are among those expressing interest in the supercomputer technology. According to the article, negotiations were underway with potential customers who could use the university's installation itself, or obtain rights to build their own supercomputer based on the university's technology.

I do remember another source though.

What?!!?!? WTF?? The government actually doing something right?

Good news for Apple. Good news for the Army. Bad news fo' M$ and DuLL.

[nuclearwinter]

WTF?!?!?!?!?!?! This is totally sweet! I am flipping out!

I remember a site (maybe it wasn't foreign) that listed the reasons as to why the XServe G5 (or was it the PowerMac) wasn't shipping. One was because the US Government (I think) was purchasing 1500+ systems and another reason was something that was going to get someone at Apple in hot water. There were like 3 or 4 reasons.

ARGH, stupid memory.

I wonder if they'll run into any bottlenecks using gigabit ethernet instead of InfiniBand. Would that affect them truly reaching 15 teraflops...

In related news, the new list of the top 500 super computers just came out, and I can't find Virginia Tech's Powermac G5 cluster anywhere on it. Did it really slide from #3 all the way to 501 and beyond?

EDIT: I answered my own question. The article states: "System X, which vanished from the most recent list for upgrades,"...

If you read the article, it mentions that they don't need the network bandwidth that the Big Mac needed. We'll see.

I wonder why that would be ... isn't network bandwidth one of the primary factors that kill the speed of cllustered computers?

It's not on there because they're in transition to an Xserve-based setup. Apple sure must've taken a hit for that, given the delays of delivering the new machines.

It could be the way the processing is done. There would be a difference between transferring digital media files and transferring mathematical data, though.

With this news and the news previously about the USarmy icons for the login this is looking good for apple.

And I remember people saying that Apple is going to go out of business in another 20 years.

[mactarkus]

As someone who works for the Department of Defense, this purchase of Apple computers is monumental toward more widespread adoption of the platform. You see, the US Government = Microsoft. Even Linux is still a hard sell most of the time. I remember there was a big purchase by the US Navy a year or so back to outfit a submarine. I wonder how that project is progressing.

Its true. Apple really needs to get over their "we make great products but have no idea how to produce them in volume" problem...

It depends on the application.

The important factor is the ratio of the amount of data needed per "work unit" and the amount of CPU time needed to process the "work unit".

By far one of the most massive supercomputers around is the one doing SETI@home - and it's running on dialup, DSL and cable modems. The key is that it needs many CPU hours of work on a data packet of a few hundred KB.

For MPI jobs like LINPACK, however, you need to work on a few KB of data for a fraction of a second.

A slow or high-latency network will kill MPI performance. It won't matter for video rendering or other tasks with the right profile.

Cool Beans. Go USArmy!

May the calculations of this computer help protect our awesome troops around the world.

As a general rule faster interconnects=faster clusters....
But this is very Problem/Code related....

If your particular code does alot of message passing then a low latency interconnect such as Quadrics, Myrinet, or Infiniband is the way to go....

But some Problems are so CPU intensive... that they are literally CPU bound and for these Codes low latency interconnects are not as important...
And you can get by with Ethernet

Since they say they dont need a high speed interconnect, I would expect that their code is like the later

Would seem like flight simulations would need speedy networking also. I guess we'll see once they get it up running. BTW, I did read that statement about networking needs in the article, but it still left me wondering.

Well put!

Hey, the government/DoD is not anti Mac and pro Microsoft. You could order any computer as long as it ran Windows natively and had Microsoft Office installed!

I really enjoyed it when the Army switched over from NT to Mac servers. It was so fun to see the look on the IT folks faces when I informed them of the change. Total disbelief.

...Of course I gladly enlightened them!

Didn't hear about this. Good news!

I remember the ship (destroyer I believe) that was run on WinNT that totally crashed and they had to tow it back into the yard to fix it. Funny!

As an added bonus, the Army will probably spend a good deal less worrying about software security issues.

It's good to see people who make decisions based on the bottom line choosing Apples again.

(And let's keep this thread out of the political section.)
