1) Message boards : Number crunching : Uploads / Downloads have stopped working. (Message 4907) Posted 23 Oct 2021 by timk Post: I'm having problems, too. Nothing has uploaded for weeks; there are 18 tasks stuck in status "uploading." All are now past their deadlines, and there doesn't seem to be any way to delete them. Event log reports "transient HTTP error." Any ideas?
2) Message boards : Number crunching : Overriding other BOINC projects and hogging CPUs (Message 2923) Posted 7 Jun 2018 by timk Post: Thanks so much for that. I tried it, but the Universe@Home tasks keep preempting the SETI ones. I have to suspend them to keep them from using all the CPUs. I used SETI@home for years before adding Universe@Home as a project; are you guys saying that BOINC is trying to balance the workload over all of my computer's history, not just in current time? Yikes!
3) Message boards : Number crunching : Overriding other BOINC projects and hogging CPUs (Message 2890) Posted 17 May 2018 by timk Post: I'm not sure what algorithm BOINC uses to allocate work among different projects. I would have thought that if I gave a score of 100 to each project, it would allocate an equal number of CPUs to each one. Not so! Universe@home consistently uses ALL the CPUs, leaving SETI@home and climateprediction.net waiting forever for a turn. It appears that the deadlines figure into the allocation of resources, and Universe@home uses MUCH shorter deadlines than these other two projects. A newly downloaded task might have a deadline as soon as a week (which may not even be achievable by some of my older computers). Other projects use longer, more realistic deadlines, and therefore get NO CPU TIME AT ALL. I have to individually suspend Universe@home tasks in order to give the others a chance. Three questions: Am I correct about the way the allocation of CPUs to tasks works (deadline dependent, among other things)? Can you make the deadlines 2-3 times longer, so my older computers have a shot at finishing a task on time? And most importantly, can you adjust things so that Universe@home doesn't hog all the resources? When I tire of playing scheduler, the easiest solution will be to remove this project from my BOINC list.
4) Message boards : Number crunching : GPU not being used... (Message 2889) Posted 17 May 2018 by timk Post: I use SETI@home to keep my GPU busy.
