What are you trying to do? What is your definition of a project?

I define a project as Lattice, or Einstein, not the tasks they give out for your processors to run. Do you do that as well?

Are you expecting all your processors to run one task at the same time? The projects you run don't do multi-threading as that's called. As far as I know, only the AQUA project does so.

Or are you trying to run at 20% of the available CPUs (cores) only (with the option "On multiprocessors, use at most 20% of the processors"), making it run at 1 core on your 8 core ((INT (8 / 100) * 20) = 1) and none on your 4 core ((INT (4 / 100) * 20) = 0) ??

Or are you trying to throttle to 20% using the "Use at most 20 of CPU time" option in your preferences?

Any of these 20% preferences, are you trying to set those through the global preferences at Lattice or Einstein? If you are, when you exit and restart BOINC, do you see a line in the messages which says "Reading preferences override file" ?? It'll come immediately after the list of projects you're attached to and where the global preferences are read from.

If this line is in your messages, you are using the local (advanced) preferences, which override the web preferences. You can get these things quite easily by just going there for a peek at what they are and accidentally clicking the OK button when you exit. Clicking OK will immediately save the preferences and use them, they will override any of the same preferences you set through the web sites. They will continue to override these preferences for as long as they're in place, no matter how many times you change the web preferences. You will have to delete the overriding preferences, before the web preferences stick:

BOINC Manager->Advanced view->Advanced->Preferences->Clear.
(Or in BOINC 6.11 and 6.12, BOINC Manager->Advanced view->Tools->Computing preferences->Clear)

I downgraded back to 6.10.56

You do know that your signature says6.10.58? :P

Oh and thanks for answering my questions. For a next time, remember that we're trying to help on any information you give. When you do something in the mean time without telling us, it isn't our fault you see something different all of a sudden.

As for diagnosing what went wrong where, I am not even going to try it. Not interested anymore.

Sandman,

I'm only going to say this once, even though you seem to be intent on repeating your assertion in every thread here.

BOINC v6.10.58 runs on all available cores just fine. My two remaining installations (4 cores and 8 cores) are running 4 and 8 tasks, respectively, as I type.

It's always possible for you to throttle it back to a single task through unplanned, or incompletely understood, preference settings, but that's something under your, the user's, control. It can be reversed, if you can be humble enough to ask for, and accept, help.

But I'm afraid that if you continue to post untrue statements on these boards, you may find that the willingness of your fellow volunteers to help you resolve whatever problem you have starts to diminish.

I have an idea. Sandman192 is running AQUA on both machines. I've already observed AQUA tasks waiting on my computer to be run, and some of the cores were idle. I've mentioned this also on the Alpha mailing list.

Sandman192's bad that he mentioned just the two projects, not the others which are waiting to be run... And that he gives up that fast.

I can confirm it just now, my computer (with "max CPUs used: 3") runs one GPUgrid (0.05 CPU) and one CPDN (1 CPU), another CPDN (1 CPU) and AQUA (3 CPU) are waiting to run.
There is even no third single-CPU task to be run, when the AQUA is preempted (which also is now :) - I'd say two flaws at once. I've already switched some debug flags a couple of hours ago, but not parsed the logs yet.

A couple of hours later both CPDN (well, actually 2 projects, CPDN beta and the regular climateprediction.net) tasks were running, AQUA task sat waiting and there was still no other CPU task available.
