Message 11414 - Posted: 18 Feb 2009, 13:55:21 UTC - in response to Message 11410.  

It's my personal opinion, but I think that a full list of compatible GPUs might be great, because I can read here and there some questions about the compatibility of cards. Maybe the label "HD38x0 or HD48x0" isn't clear for all people. Maybe something like this :

Compatible Cards :

- ATI Radeon HD 3840
- ATI Radeon HD 4850
- ATI Radeon HD 4870

Cluster > do not be offensed by my next question : do you want a simple html/css code to present your different pages ? With some nice tables, colors, etc. ?

If you do that, and it's in these MW forums, I'd be happy to link zslip to reference it.

You can take a look (it's an alpha version ^^) :

Just to get an idea. You can take the code of course ^^

Well, it's certainly a well laid out table and easy to read.

I'm always pleased to take advantages of improvements, so if you're serious in that I can use the code for your table, I might just do that. Thanks ;)

I'm serious. It took me 5 or 10 minutes to do that, so it's not a big work ^^

Take everything you want. If you want me to do something else, do not hesitate ^^

Many thanks for that Exar Kun. I have imported your code into zslip.com and tweaked it just a little bit.

I think it's a great improvement - thanks ;)

You should mention cat /proc/cpuinfo for the linux CPU capabilities.

Good suggestion Exar Kun and well done Ice for implementing it

I certainly will do, but preferably by linking to that information here. If it's posted here in MW I'll add it to zslip or link back to here as appropriate.

Message 11510 - Posted: 18 Feb 2009, 22:06:54 UTC

@ Cluster Physik:

Does CPU speed matter in re: to GPU application? or does GPU app not have any significant dependency on CPU? Would one expect a major difference running Pent D or AMD X2 for example vs. a Core2 CPU?

Thx.

As not the whole computation is done on the GPU (just 99.5% or so) it may have a small effect. But I would say it is less than one second difference per WU between a P4 and a Core2 for instance.
Quite a bit of this CPU computation time can be hidden when running 2 WUs (or more) concurrently. When one WU waits some milliseconds for the GPU to complete the current task, another WU can calculate its CPU part.
That's actually the reason I've integrated the possibility to run several WUs concurrently. It slightly increases the efficency. For slower CPUs it just pays off more.

Thanks for answering my question. Excellent! Also...this is good news as I have a PentD 945 & ECS C19A MB that are brand new, but it never seemed worth building after Core2 came out.....until now.
Just need to add an ATI 4850, load-up xp64 Professional & it will have a legitimate new purpose.
Cool!

Edit: Last question. How many WUs can a card run w/o any performance degredation w/ 512MB GPU memory? I understand throughput remains the same untimately, but I'd be inclined to run a greater # of WUs vs. individually if there's not a performance penalty.

When can we expect a 32-bit version? I'm so excited! :D

EDIT: I found both versions here.

EDIT2: This is what I'm getting from the 32-bit app on a 4850.

Aha, I fixed my Issue, turns out my CCC was slightly corrupted. A reinstallation fixed it.

Edit: DAAAAAAAAAAYUM!!! Nearly a credit/sec of CPU time. Amazing!!

I just saw the new 32 bit version for ATI GPU. It's a good news, but is there any performance difference between 32 and 64 bits ? If the calculation times are the same, I will come back to my Xp 32 bits ^^

Another question (sorry if it's stupid ^^) : why the optimized application, specially the GPU app, are not available on the MW website with a big-red-flashing font ? :) I found this thread only by (extreme) luck, and I think that a lot of people don't know they can optimize their participation. But maybe it will be a charge to heavy for the server ?

Because the developement is not finished yet. It runs, yes, but there are still some issues that should be resolved before it is ready for prime time. There are some reasons why the thread title is "GPU app teaser" and the applications are clearly labeled as an alpha test.

The 32Bit variant exists 20 hours now and the very first feedback indicated there may be some problem with XP32 and the HD3800 series cards. It is not tested much (the 32bit compilation not at all, I have no possibility to do it). That's the reason a small scale test may be better in the beginning than to have to pull back a faulty application after a full blown rollout.

Is this list updated.. I am doing a quick inventory on my hosts and to my surprise I have found several with ATI cards.. Not sure if they are compatible...
