I've started a new run:

de_separation_13_2s_sscon_1

This one should be shorter than the previous ones. As always, please let us know if you run into any problems.

Message 58086 - Posted: 2 May 2013, 6:32:18 UTC

I noticed that the amount of credits is much lower than for the other WU. On my 7950 on WU 13_2s_sscon_1 needs about the same time than the other WU but earn only 79.94 credits instead of 106.89.

I see a noticeable credit drop.

Can you please adjust the credits for this type of WU?

Thanks

No credit issues here, also in case of the separation_13_2s_sscon_1 WUs my HD3850 has to work 5.06 seconds for to earn 1 credit, that's EXACTLY what I always get as long as the GPU has nothing else to do, i.e. displays nothing else than the desktop or, after a while, the screensaver.

Looks normal on my 5850 too.

@Nowi
For a 7950 at 900 MHz you need a lot of time per WU.
You must either run 2 WUs at once or your target frequency of 10 does not fit at all to those short WUs (even those with 106 credits).
Give it a try with 1 Wu at once and default target frequency of 60 to see how your times are than.

Yes, I use normally two WU per GPU.

I tried your hints. Here are the results:

target_frequency -> 60: about the same time
one WU per GPU: de_separation_13_2s_sscon_1 about 4s slower than all other tasks

Info: using Boinc 7.0.64 and a driver 12.6 or 12.8

Sorry for double post, but I can't edit it:

I solve the problem. I rolled back driver to 12.6 and now the 13_2s_sscon_1 are shorter.
