Why does CreditFew Award Fewer Credits when my GPU is matched with a CPU than with another GPU?

. . Exactly, credit given is useless when on any given system working at its configured optimum the numbers can go up and down on a daily basis like a fiddlers elbow. In the end it means absolutely nothing. It needs that consistency which CreditScew lacks. Stephen :( |

It does, or should, work the same for aborted tasks Currently "aborted" tasks are not considered as "Error" tasks, in the same way as "Download Failures" don't count against the user. Like you, I feel that "aborted" tasks should count against the user and result in a reduction in the daily allowance of tasks delivered in a cumulative manner - Something along the lines "abort x tasks, allowance reduced by y%" until back to "free flow", which can only be achieved if there are no more aborted (or error) tasks during the recovery period, more tasks aborted resulting in a reduction in the allowance, ending at one task per day until you stop.

Essentially credit is awarded based on CPU performance. The number of "FLOPS" is estimated on a fairly simple calculation for a CPU, then scaled for a GPU. This scaling assumes that all tasks are the "same type", and thus the same scaling can be applied - and as we know, this is not correct, particularly for VLAR tasks that take proportionately longer on (nVidia) GPUs than CPUs, (and, I think, VHAR actually take proportionately less time on GPUs than CPUs).

I hope that if you folks come up with a proper solution to the CreditNew downward spiral that you can find somebody to code it and put in the fix. The kitties are not holding their breath, but would welcome the repair. It is rather disappointing when one upgrades a rig and is rewarded with it's RAC declining......LOL.
