Hello,

My system has two nagging problems with Milkyway@home processing. I run multiple Boinc tasks on my system since I have multiple cores to keep occupied. I currently have Seti@home, Milkyway@home, Collatz Conjecture, and GPUGrid running. First problem, unless I suspend the other projects, when Milkyway@home updates (either automatically or manually), it usually logs the message:
Milkyway@Home 9/10/2015 4:03:57 PM Not requesting tasks: don't need
This is regardless of whether it has work or not. Is there a way to get it to request work without having to suspend the other projects? Secondly, I have it set to run 4-5 instances of Milkyway@home at once, but it won't download more than around 24 workunits. It will leave a message about the number of allowable workunits being exceeded. Is there a way to increase this limit? Currently, I don't get enough workunits for more than about 3-4 hours of processing, at the end of which I have to suspend the other projects to force Milkyway@home to request more work.

Thanks, Jon.

This is the Boinc software doing it's 'scheduling' algorithm that it does, in time you will get units from each project, although probably not all at once. If you go into your account, project preferences you can change the percentage at the very top to different amounts. This can help if for example if you leave MW at 100, but put Collatz at 50 and GpuGrid also at 50, then MW will do twice as much work, averaged over time, as the other 2 projects.

As an aside if you put a zero in that top box then the project will act as a 'backup' project in case your main one runs out of tasks. The zero means it will only get enough to tasks to run right now, but have a zero cache of extra units. Then when Boinc needs new tasks it will ask your higher priority projects first, getting tasks from the zero project only if the others don't have any.

As for downloading more tasks than the project allows, that is probably a non starter, they set those for a reason a long time ago. If the project gives me, for example, 7500+ work units, my gpu is doing them in about 45 seconds each, then that is alot of units that others can't get, putting more strain on the Servers to make even more workunits for others. At 60 seconds each times 24 hours times 5 days is 7200 workunits, you can see the need for a limit.
