	BAPRIEBE I was having a similar issue of not getting seti WUs when I had several other boinc projects suscribed on the same computer. As others have already stated, boinc will fill up your cache with the other projects when it cannot get WUs from seti. This issue is compounded with the very long retry delays in boinc 6.12.34, that you are running. So, based on recommendations from other posters here (Thank you, Claggy), I switched to boinc 6.10.60. Now, I typically have a full cache near the WU limits. What I have noticed with boinc 6.10.60 is that its WU download retry intervals are short. Therefore, I don't get into a situation where an unattended boinc rig has a 4 hour delay before trying to download a WU again. This extended delay allows the cache to be filled by the other projects. BTW, I think the seti WU limits are 50 per physical CPU core and 300 per GPU. Cheers, ____________

	50 per CPU core, and 400 per GPU are the current limits. Double CPU's help, such as GTX 295's, as they double the amount of work allowed. Steve ____________ Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website

Is that actual physical core or thread? That's total number of threads, and GPUs, my i7-2600K/GTX460/HD5770 has a limit of 1200, 400 per GPU, and 400 for the CPU (8*50), Claggy

Is that actual physical core or thread? If you don't modify anything it will use the total # of cores, virtual and real. If you have imposed a limit via "use at most x% of CPUs" or have limited the processors in your cc_config.xml then that will be used. If is you set use at most 75% of CPUs, in a 8 core system, and have BOINC to not use 1 of 2 GPUs for S@H. Then you would get 300 CPU and 400 GPU tasks instead of 400 & 800. ____________ SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the BP6/VP6 User Group today!

	There's also the <ncpus> option in cc_config.xml to override boinc's CPU count detection. It can be used in combination with "use at most % of cores" option in preferences... ... ____________

	I have overridden number of cores by modifying cc_config, from 4 to 2, and I still get 200 CPU workunits. My limit is 1000 atm and I have two GPUs, while, as written, only 2 cores are acive. ____________

	I keep having this message even with zero GPU tasks and like 40 cpu tasks in a six core/five gpu machine for weeks now. It just happens with my biggest rig, the others, smallers, get much much more work. Frustrating to say the least. BTW I guess this is the case with all top crunchers, they are all out of work and not getting any. ____________

Since your computers are hidden we can't get any hints from the web pages. It just happens with my biggest rig, the others, smallers, get much much more work. Frustrating to say the least. BTW I guess this is the case with all top crunchers, they are all out of work and not getting any. Checking the first ten top hosts, on average they've gotten 759 GPU (MB) tasks today (Berkeley time, approaching 10 am now). Joe

	something is all hosed up again on the server side as my small queues are draining again this morning... I'm sorry it must have been my machine sucking up all of the work. Looking at the logs from overnight for my machines most of them are bouncing off of their limits & I don't see any failed connections to the scheduler. Also I only seem to have 13 transfers across the ~30 machines. Do you have a lot of active transfers? Which would cause BOINC not to request new tasks. I remember that n cups * 2 is one of the formulas used to stop requesting work, but I think that is for uploads. ____________ SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the BP6/VP6 User Group today!

	Partly my fault as well seeing as all mine have been feeding very well but still bouncing off/on their limits. Cheers. ____________

Checking the first ten top hosts, on average they've gotten 759 GPU (MB) tasks today (Berkeley time, approaching 10 am now). Joe They aren´t hidden anymore. Even then, my top rig is at #1 position right now, so i´m pretty sure that´s there is a problem, but it´s not with my machine, because I don´t own the most powerfull machine out there. So the big guns aren´t having work on the past days, obviously. Have to say that that machine it´s having work on the past 24 hours, without any change on my side too, and even building a cache, so something was fixed at that time. ____________

	Forget the "cache" thing, they are all running dry again. ____________
