	I saw \"GPU Grid - PS3 Grid\" in BOINC project list. I thought PS3 Grid is only crunching on PS3. Does it support GPU now?? If so, which GPU(s) are currently supported?

	There are 7 users with failed workunits at startup. It would be very useful to know what they are running (OS, GPU, driver version) in order to understand the problem. REMEMBER THAT YOU NEED TO UPDATE THE BOINC CLIENT (6.3.5 ubuntu) FROM THE LINK THAT I HAVE GIVEN ABOVE. YOU CANNOT USE AN OLD ONE. Many many thanks. gdf

	Results here Hello, Can you tell us which GPU and drive you use for comparison? Thanks I would say that any GPU with over 100 cores is good. We have 8800 GT, and 9800 GX2. We want to support multiple GPUs not in SLI mode, I have not tested it yet. A machine with a quad code cpu and 2 9800 GX2 would crunch more or less 20,000 credits/day.

	Hi My 1st GPU work unit completed just fine, the next 2 failed and the 4th is running now. Also had a machine crash just after the 1st WU completed. Results here The 4th WU has just completed after 4 hours but failed validation with process exited with code 1 message in stderr out (same as the 2nd & 3rd WUs). I've set No New Work for the moment.

	I tested two drivers, 173.14 and 177.13, no difference I initially had 173.14 installed (from here) but wasn't sure if that was a cuda driver or not So followed the http://www.nvidia.com/object/cuda_get.html link and it suggested the 169.09 package for my setup.

	So what do you guys think? It appears my older Nvidia cards don't support CUDA. :( Looking for a card to put in my dedicated cruncher for this project. I think I have settled on this: ZOTAC ZT-98XES2P-FSP GeForce 9800 GTX ____________

	The 9800 GTX shouldn't be a bad cruncher, you can see the runtimes per WU of my card in the other thread you started... But if you would like to, or are able to spend a little bit more money on the graphics card, one of the new GTX 260, or GTX 280 cards would be much faster! But for a GTX 280, you would probably also need a new PSU, because it needs a 8pin plus a 6pin power connector - the GTX 260 only two 6 pin connectors... ____________ pixelicious.at - my little photoblog

A way to know which card is better for the money do this: Compute the peak Gflops of the card. Peak Gflops = (shader clock)x(number of stream processors)x(3 flop) The highest the better. GDF

	Thanks guys! What I would like to know, is how CPU intensive is this? I am imagining the GPU is doing most the work. A core is tied up with it but not running 100% like we do with "traditional" projects. So my conjecture/question is if the same RAC, with whatever card, can be achieved with a slightly slower (read cheaper) cpu? I am very keen to see if it will be successful to run multiple tasks on multiple cards simultaneously. If all my assumptions above are correct. Then rather than spend more to get a faster card, that ties up one of my good crunching cores. Wouldn't it be cool to build a budget dedicated twin or even quad GPU cruncher? I invision two of the $200 dollar cards. (although if one had the funds the GTX 280 is an amazing machine) A basic $50 atx board and a $50 processor, probably a 4200+. Using Stefan's numbers that would be like 8-10k RAC a day for the price of a PS3. Really exciting development you guys have here. I will do whatever I can to encourage this technology. And to think I thought the Cell BE was cool. ;) ____________

A core is tied up with it but not running 100% like we do with "traditional" projects. Actually the application uses also one core of the CPU to 100% plus the GPU as coprocessor... I really can't say how important the CPU speed is for the GPU application, but earlier test have shown that if the app uses only 50% of a CPU core, the WUs were a good bit slower. Would be interesting to see some comparisons with the same graphics cards but other CPUs in the thread you started... ____________ pixelicious.at - my little photoblog

It appears to be using 100% of resources just because it is polling waiting for the accelerated kernel to finish. So, any CPU should do. We have built a machine with 6 GPU cores by putting together 3 Geforce 9800 GX2, a power supply of 1200W, an Nvidia 780i motherboard with 3 PCI-E 16x slots and a quad core CPU. We are looking into building another one with Geforce 280. GDF

GDF Could your clarify this. Does a GPU task use only 1 CPU core and all avaialable GPU cores, in this case 6, or does each gpu task use 1 cpu and 1 graphics card (2 gpu cores) or just 1 gpu core ? So your rig above, how many gpu tasks could run at the same time to use all cores, and how many cpus would that use and how many cpus would be left for other boinc projects ?

	Results here Hello, Can you tell us which GPU and drive you use for comparison? Thanks I would say that any GPU with over 100 cores is good. We have 8800 GT, and 9800 GX2. We want to support multiple GPUs not in SLI mode, I have not tested it yet. A machine with a quad code cpu and 2 9800 GX2 would crunch more or less 20,000 credits/day.

	The 9800 GTX shouldn't be a bad cruncher, you can see the runtimes per WU of my card in the other thread you started... But if you would like to, or are able to spend a little bit more money on the graphics card, one of the new GTX 260, or GTX 280 cards would be much faster! But for a GTX 280, you would probably also need a new PSU, because it needs a 8pin plus a 6pin power connector - the GTX 260 only two 6 pin connectors... ____________ pixelicious.at - my little photoblog

A way to know which card is better for the money do this: Compute the peak Gflops of the card. Peak Gflops = (shader clock)x(number of stream processors)x(3 flop) The highest the better. GDF

	Thanks guys! What I would like to know, is how CPU intensive is this? I am imagining the GPU is doing most the work. A core is tied up with it but not running 100% like we do with "traditional" projects. So my conjecture/question is if the same RAC, with whatever card, can be achieved with a slightly slower (read cheaper) cpu? I am very keen to see if it will be successful to run multiple tasks on multiple cards simultaneously. If all my assumptions above are correct. Then rather than spend more to get a faster card, that ties up one of my good crunching cores. Wouldn't it be cool to build a budget dedicated twin or even quad GPU cruncher? I invision two of the $200 dollar cards. (although if one had the funds the GTX 280 is an amazing machine) A basic $50 atx board and a $50 processor, probably a 4200+. Using Stefan's numbers that would be like 8-10k RAC a day for the price of a PS3. Really exciting development you guys have here. I will do whatever I can to encourage this technology. And to think I thought the Cell BE was cool. ;) ____________

A core is tied up with it but not running 100% like we do with "traditional" projects. Actually the application uses also one core of the CPU to 100% plus the GPU as coprocessor... I really can't say how important the CPU speed is for the GPU application, but earlier test have shown that if the app uses only 50% of a CPU core, the WUs were a good bit slower.

It appears to be using 100% of resources just because it is polling waiting for the accelerated kernel to finish. So, any CPU should do. We have built a machine with 6 GPU cores by putting together 3 Geforce 9800 GX2, a power supply of 1200W, an Nvidia 780i motherboard with 3 PCI-E 16x slots and a quad core CPU. We are looking into building another one with Geforce 280. GDF

So your rig above, how many gpu tasks could run at the same time to use all cores, and how many cpus would that use and how many cpus would be left for other boinc projects ?
