Two words: CUDA, 280 however... SuperMicro X7DA8xx series are our current series at work. We buy top of the line XEON's with fancy coolers, and chassies that suck up small animals when they pass by. with an oct core you can pull about 800Gflop. With dual nv280's and some learnin' you can pull up to 2Tflop. 1 Tflop without pulling some magic. Combine the two and you have 1.8Tflop of computational power. :) mmmmmm makes me want to drool.... I have single quad+ dual 280 at home. :-D

Dual quadcores you say - how about something based around an Intel SkullTrail? edit: now how would this cause confusion? "dual" means "composed of 2 parts" as we all know. 2 * 4 = 8. It's not like I'm saying "core2 duo quad" or something nonsensical like that.

I've heard good things about BOXX machines. Lots of options - their APEX machines go up to 32 cores, I think. Haven't tried 'em myself though, but worth a look. Check 'em out here[^] Cheers, Drew.

Awesome! And thanks--you're the first person (though others followed, to give them credit, hehe) to actually provide me with a link to an actual workstation I can point my client to. Marc

see "Dueling Banjos" is an instrumental composition that was made famous in a scene from the 1972 movie Deliverance. [^] and this.[^]

My client would like me to recommend a system that has 8 cores, which I guess would be configured as two processors with quad cores. So I ask the experts here. Why, you may ask? Because we're running very computational intensive analysis on some switch network topologies used in communication satellites. So the quality of your next TV show or Internet connection might depend on the analysis we're performing! mac
This motherboard[^] has four 940 sockets and supports up to 32GB of memory. It takes the 800 series processors.[^] It's a bit on the expensive side. :)

You need to diversify your habits there's great joy to be had in smoking electronics and mechanical systems of any sort. The most expensive hardware I've smoked is an AC compressor in my old car I was quoted $700ish to replace. Fortunately it was late summer/early fall and I was able to wait a few weeks and have my dad fix it for cost.

I can't recommend a pre-built system as I built my own 8-core box, but maybe I can help. For a new computer dedicated to "computational intensive analysis", you now have two options: CPU and GPU. CPU: I bought 2 E5420s because they cost $700 for two, whereas the cheapest of the new 1600MHz FSB ones cost $1000 each. See Intel Xeon 5000 series datasheet[^]. I didn't think that three times the cost was worth it for about a 10% increase in performance. GPU: I have a single NVIDIA GeForce 9600 GT which cost about $200 and has 64 cores. I ported my PetriDish[^] article to CUDA[^] and immediately saw the equivalent of 16 CPU cores. It really wasn't that hard except you have to use VS2005. That was my first try at CUDA too, so I'm sure someone who knows what they're doing could get better results. So, for a one off purchase, I'd say it's probably easier to get the client to fork out for an 8-core box. But if you intend building a few machines, it's probably worth porting your concurrent code to CUDA and buying GPUs as they are much better value for money. As for the other components, I always use brand names ( Tyan for motherboards, Crucial for memory, etc. ) as I believe you get what you pay for here. HTH Nick

With that much computing power, could it be time to check into distributed computing and maybe spread that load a bit? They probably have machines with some available CPU time already.

We've got several Dell Precision T7400's at work configured with 2x Quad Xeon running @ 3.2GHz. I'd strongly recommend getting the fastest hard disks you can afford as this much CPU power can be bottlenecked easily by slow disks (if that's the nature of your tasks). Don't skimp on memory either, go 64bit and these machine support 32GB of RAM!

Another option that might be worth thinking about is grid computing - that way you can effectively lump existing machines together to pool their processing power. We've been experimenting with the IncrediBuild grid console [^] (xgconsole) for distributing computationally intensive code analysis tasks, and so far it looks very promising. If your task can easily be broken up into independently executing processes, it's definitely worth a shot. :cool:

I smoked an LED clock as a teen - didn't care for it much.... now I am much pickier about my smokes. :) I have smoked half a dozen computers once. Each about 4k. In my defense, I powered on the van and the power cable outside started arcing. The machines powered on 2 seconds apart. I saved half the computers and the onyx which powered up last. But it took me 6 seconds to reach the master breaker and kill the power.

Thanks. I'll pass that along.

Disk performance and memory are not issues. Only processor performance. :) Marc

It's definitely something I'm considering as well. At this point I've modified the code so that the analysis can run in a truly autonomous manner, so it can be easily distributed. Woohoo! Marc

It definitely can, now that I've made the necessary code changes. The problem is getting machines available. I could throw 8 cores at it distributed over 4 computers, but I'm not sure my client actually has those resources. I mean, they have thousands of computers, but it's all a very secure environment and each person only has one workstation (the last time I visited, granted, a few years ago). Getting someone in the cubicle next to you to donate their machine (even if only some % of CPU cycles) I think would be difficult. But I'll ask. :) Marc
