Odd WU assignment slow GPU gets high value

Post by cnb »

I am running on Windows 7 Professional 64 bit, with FAH version 7.3.6 on a i7 CPU 940 @ 2.93 Ghz . I have two GPU clients (a GeForce GTS 450 and a GeForce GTX 770) I notice that the old slow GPU is being assigned higher value WU than the newer faster GPU. For example the GTS 770 is currently running PRCG 8018 (1151,0,149) with estimated credit of 5757 while the slower GTS 450 is running PRCF 8900 (502,6,68) with an estimated credit of 20215.

System info identifies the GPU 0 as the GTS 450 and GPU 1 as the GTX 770


Is that correct WU assignment, and if not, what do I need to do to correct the assignment?

Welcome to the forum.

There's nothing unusual there. Fermi and Kepler cards get the same project assignments, and the project distribution is weighted random. The effects of QRB, which is present on core 17 projects such as 8900, usually cause each WU to be worth more than a WU from a core 15 project, which does not have QRB. Until all the core 15 work is completed, which is not likely to be anytime soon, expect to see situations like this somewhat frequently.
