On Christmas day, one of my computers was processing 8 vlar WUs downloaded from the beta site, which had all started at the same time because of preemption. 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.

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)

How many days is your Boinc cache set to?

10 + 10 = 20 days. 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.
