For now GPU's are, by far doing better than CPU's. Just doing a little investigating I have found one member who is doing over 50 times its average number of results. 4600 results yesterday with only 18 devices or an average of 255 results per device. That would mean over 10 per hour or 1 every 6 minutes. It is interesting that the members in the top 3 in results have not seen much of an increase. I guess IBM is not doing much investing in GPU's. The total number of results today will probably double the number of results of just a little over a week ago(10/10/12). CPU time and points will have increased by around 20 per cent. I have done like IBM and have invested in CPU's and until there is a promise of at least one project that can use a GPU, I will not go out and invest in a lot of them. My best GPU (NIVIDIA GeForce 9400 GT) will not work even though it has a Gbyte of memory.

So whether you crunch a thousand units in 24 hours or just one unit in 24 hours you STILL get one days worth of credits! Your gpu won't work because it is not OpenCL compatible, I believe. That is the MINIMUM requirement and they will go up from there as time and workunit experience evolves.   |

Hi mikey159b,
So whether you crunch a thousand units in 24 hours or just one unit in 24 hours you STILL get one days worth of credits! Actually, a GPU generates far more BOINC credits in a day than a CPU does. A few days ago knreed said that most (about 60%) of the HCC BOINC credits were from GPUs. This percentage should increase as more people learn how to use their GPUs on HCC. Lawrence |

In a way you are both right. WCG is rewarding people (Badges) by their Run Time. mikey159b is right A GPU can do more work units in a day than a CPU (in general), so the GPU can generate more Points in a day. lawrencehardin is right ------- Some of us have been using GPUs for Folding@home and other BOINC projects for many years now. This should have the effect of making the learing curve for GPU use here at WCG very quick. It seems that most of what has been learned in other projects can be directly transferred over here. |

I was referring to results not credits. The total number of results per day has nearly doubled from the 10th to the 19th. I am a little jealous of someone who can get a result in a little over 5 minutes and I had one result which took over a day. Meanwhile I have gone from around 200 results a day to around 125 a day with the worst day of just 87 results.

This will be quite a thing to get used to. I just recorded 3100 results returned today, all from GPUs.

There were over 1.3 million results returned yesterday but over 917 thousand were help conquer cancer. So the vast majority of them are help conquer cancer. Most of which are coming from GPU's. I have fallen 7 places in the standing of results returned but I have not fallen in run time or points. This must mean that all those results are adding very little to run time and points. A quick look at stats bear this out since run time has increased by around 15% and points have increased around 33% but results returned have more than doubled. I had thought that since one of my computer tells me that my GPU is Cuda qualified that I too would have a number or GPU results but unfortunately that is not the case. I think that there will be more results returned in the next 6 weeks than there were in the first two years of this project.

Hi RicktheBrick
----------------------------------------You may have to make a change in your device profile to opt in to GPU crunching As for me I'm back at GPUGrid with my GFX560ti as running WCG HCC on my GPU causes my whole PC to judder almost to a halt (my RaspPi is faster) The duty cycle of the GPU is also about 50% as the WU holds it while the CPU zips up the result for return - this isn't particularly efficient and causes the GPU to temperature cycle. GPUGrid can keep my GPU running without issue for very nearly 24/7 + the remaining bit of CPU Core gets to crunch for the WCG - so everybody wins 7 WU's running on a 6 core machine  Dave  |
