    Computer question

    Anyone know if I would get better performance from a 6-core Xeon X5680 or 2 quad core Xeon 5630s? I'm using it for computational fluid dynamics research and everything else in the computer will be fast enough that the difference in processor speed makes a real difference. My boss wants me to figure this out before we have 'the talk' with our IT people where we tell them what to buy.

    I don't know, but I salute your victory in the hardware wars. Please don't tell my computer, because it will feel vastly inferior compared to that beast.

    Not much of a victory, due to the fact that if I were to install games on that computer, my boss would probably kill me.

    Is the program you are going to run multi threaded?

    It can be. I can set it up to run on as many cores as are available.

    Re: Computer question

    The extra 12 mb of cache could come in real hand with the dual core setup. But honestly I doubt there would be a really big difference either way. I would go for the most bang for my buck.

    Just get 2 6 core processors and sleep better.

    Unfortunately that is out of the budget right now. We're getting a cluster once the next round of money comes in next July, but for right now all we can afford is either 2 quad cores or a single six core. The quad cores are each at 2.53 GHz while the six core is at 3.33 GHz.

    That is starting to look like an option, unlike calling dell. I called dell earlier today and was told, 'we don't provide benchmarks'. Almost made me want to say 'and we're not going to be buying our cluster from you next year'.

    I just finished setting up a hyper-v cluster with dual quads, running 30 virtual servers and it doesn't even break a sweat. If your testing can take advantage of 2 processors I would say that is the way to go.

    Wow, so you are that guy running hyper-v? I thought it was just an urban legend.

    Re: Computer question

    Without looking at any benchmarks, I would say the dual quad would be the way to go over the sex.

    This is probably bad math, but 8*2.53 is almost equal to 6*3.33. This is just trying to look at the potential "total power" for each setup. With that in mind I think I'd be more likely to go with the 8-core setup. When you use multiple cores they won't always be running at 100%, and I'd personally prefer to have 8 cores running at whatever capacity as opposed to 6 cores running at the same capacity. I'm also assuming that your program would work just as well on 8 cores as it would on 6 cores.

    I'm going to make a prediction- whatever you choose, your IT people will think it wasn't the way to go.
