    Re: FAO: Directx and other GPGPU freaks

    These could come in handy at present at work. Send a free sample and I am sure we will tell you if they are worth stocking or not I am sure Jo wouldn't mind a sample to

    I have to admit, this looks **** hot. Proper MIMD, innit.

    Now, let's all get used to writing code without branches
    PHP Code:
    $s = new signature();
    $s->sarcasm()->intellect()->font('Courier New')->display();

    Re: FAO: Directhex and other GPGPU freaks

    I want a sample as well

    I dunno what I would use them for at home. Maybe a little bit of folding @ home to help the hexus team jump up the tables, thats if folding can be accelerated by them.

    Several for my underground base wouldn't go amiss, either.

    The ECC stuff is very interesting as well.

    Well it is and it isn't. Modern fabrication processes are technically capable of handling a LOT more transistors than we put down onto them (an order of magnitude I think). The problem is with us - we can't design and (most importantly) validate that much stuff and get a product out of the door in a competitive amount of time.

    However, something like this is a lot of repeated cells so a lot easier to verify if you approach it in a sensible way. You still put a hell of a lot of effort verifying some of the higher level stuff such as the L2 sharing and rest of the busses, but I bet throwing in ECC wasn't that costly. Well, evidently it wasn't, otherwise I can't see why they'd do it!

    It'd be nice to see how all this is going to translate into the next generation of graphics cards

    .
    Well ArmA 1 was only just about playable when I had an E6600/GTX260, and that was about 6 months back... Given ArmA 1 is what... 3 years old or more?

    Looks odd. I have no doubt that we'll see something along these lines eventually - we do work with a professor from computational finance who's very cozy with NVIDIA, and got us our last four Teslas

    Re: FAO: Directhex and other GPGPU freaks

    Hmm.

    ECC is something a lot of people bang on about wanting, so thats a tick i guess.

    But for what it is we are doing, we still find its often the overhead of shifting the Market Data that is the killer, if you've got a correlation matrix style problem that requires 5GB+ of correlation data, the performance of the CUDA system we last tried it on (295 iirc) was just not as good as a high end more expensive CPU, but effecting the total system cost by a few % when you take into account an SSD RAID.

    I'm sure they have a market for it, its just I can't see it in most Trade Finding or classic Risk engines in the financial world.
