Do we need a DCF for GPU WUs?

Due to the long term succession of GPU WUs processed, the DCF declined to about 0.8, whereas normally it is higher than 1.20 when processing vlar WUs. Consequently Boinc downloaded 318 CPU WUs in about 2 hours, all of which were due yesterday (1/8/12) between 2:30 and 6:30 PM. (See the digest of stdoutdae.txt below.) Yesterday morning at 6:00 AM there were still 216 of these WUs to process. 130 of these could not be processed by the due date and were declared to be errors, thus increasing pending credit and annoying everyone in general. This might not have happened if we had a separate DCF for GPU WUs. 25-Dec-2011 16:18:40 [SETI@home Beta Test] [sched_op] CPU work request: 172352.15 seconds; 0.00 CPUs 25-Dec-2011 16:18:40 [SETI@home Beta Test] [sched_op] NVIDIA GPU work request: 0.00 seconds;

This might not have happened if we had a separate DCF for GPU WUs. It's not that simple - you (BOINC) will need several (many) DCFs for every combination of different GPU/app e.g. DCF1 - MB app on CPU DCF2 - Astropulse app on CPU DCF3 - MB CUDA app on GPU 0 (fermi) DCF4 - MB CUDA app on GPU 1 (2xx) DCF5 - MB OpenCL app on GPU 2 (ATI) DCF6 - Astropulse OpenCL app on GPU 0 (fermi) DCF7 - Astropulse OpenCL app on GPU 2 (ATI) ...

Bear in mind that this is the S@H Beta site. The CPU and GPU are so fundamentally different, there is no hope of making one DCF work for both. ID: 1186500 ·
