.....Requesting 0 seconds of work. ......

With no SETI WU in the queue that does not seem like the right choice :-( Anyone help me understand what is going on? The only recent change I made is on the SETI site to enable AP WU.

All 3 choices for work are enabled (SAH Preferences):
SAH Enhanced
AP
AP V5

Thanks

So if you enabled AP you got AP. And you got so many AP tasks that BOINC doesn't count you need any more work in near few days.
So, action=>consequencies.
Wait until some of AP tasks will be done, then if you will lucky you could get more MB work.

<cc_config>
<options>
<ncpus>6</ncpus>
</options>
</cc_config> is placed excactly where you say to and i still had 2 idle processes in task manager..

ALL OK. It SHOULD be so, they waiting CUDA_MB. You have 4 cores - 4 CPU apps running. You have 2 GPUs - 2 GPU apps running. What else you want ??

Raistmer:
This update ONLY for those who use BOINC only for SETI MB crunching. No other projects, not even AstroPulse, ONLY SETI Enhanced (MultiBeam).
In this build CPU-GPU re-scheduling is disabled (it's not needed for only SETI MB configuration).
It should increase total performance for such configs.
Again, use it ONLY if you crunch SETI MB solely.

And don't forget RULEs for opt apps updating:


1) DISABLE network access in BOINC
2) STOP BOINC
3) Copy BOINC whole data directory in another place as backup.
4) install update
5) start BOINC.
6) if all work fine - resume network access, else - stop BOINC and restore BOINC data folder from backup.

Maybe so. However I've also got only 8 AP. 4 in progress, 4 waiting. I specify 10 days of work in queue. This is not 10 days on the particular PC. So will wait out the AP WU see if I get more when the last 4 start.
