CPU work fetch seems to be inhibited by GPU one
« on: 17 Sep 2011, 02:02:08 pm »
My host downloaded much GPU work for  SETI beta, then it took some ATI GPU work for SETI main and then it decided to download ~10 tasks for CPU only.
No CPU tasks running in panic mode, transfers are absent, it's quad-core host... Why not asking for CPU work (when manually updated it refuses to ask for work!).
BOINC 6.10.58 (Jason's modded one).

What flags should I enable to bug-report this issue ?

Yes, I'm quite out of sync now - hard weeks were...

Could someone summarize those discussions in few words, please?
There was another David's brilliant server update? Most what I need to know - what can I do on my side to force work fetches go ?
Looks like this host runs w/o CPU work few days already #$%^^#$#  >:(

For our internal boinc, enable <dcf_debug> .  What you'll probably find is that normal Project DCF is completely 'wacked out', and aDCF in the modded version is at least periodically shoved hard against the lower stop (0.02) inhibiting work fetch due to there still being overestimates. 

There is nothing much to do but wait for David to fix the server side estimates, though I am having some success building a GPU cache, with further enhancement to aDCF (chopping out server side dependencies & making convergence more rapid.)  I'm currenlty talking to others about it in GPUUG, and if it takes too long for David to fix it, I might have to consider making the improved modded variant available to some to smooth David's transitions.

Well, as I understand it's known issue already... OK, will try to run re-schedule....

Seti Beta has already had a fix, Main hasn't yet, you could suspend one or the other projects to get work fetch going, then swap,

Managed to download few more tasks, but mostly got "0 tasks available". It's strange cause servers page shows lot prepared... but ~10 times in a row "0 available" for my host... [all "GPU" ones, host still refuse to ask for CPU work...]

I'm stuck in the situation, although my host needs more tasks to fill it's cache, it just won't ask  :-[
I'll just have to wait it out and do Beta tasks I guess

I think most of the work in the feeder right now is vlar, my GTX560 is empty right now. The GTX460 still has 81 tasks to run.

I got lot of VLARS yesterday for my CPU.
Since i´m not very patient i just downloaded 1900 units for CPU and reschedule what i need til APs are available again.  :P

I managed to get way too many CPU WUs when this first started so I don't have any problem there. I'll be crunching what I have for days.  I've been thinking about moving some of the shorties over to the GPU but I've been getting enough from the server to keep it busy so I haven't yet. I'm a little afraid to move anything what with the time estimates being so far off. Yesterday my CPU tasks started running high priority but seems to have settled down this morning. The estimates seem about right for my CPUs but are still way off for my GPU. Seems to think the 8-10 minute shorties I've been getting will take me over three hours to complete.

So, anyway, it is not asking for CPU work as it has way too many and it's replacing my finished GPU work so I'm happy. I haven't received any APs since this all began so I don't know what would happen with one of those.
