1) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1779) Posted 2 Jan 2023 by jm7 Post: Still no problems with any other project using far more than the allotted CPU. Something about this project is using more than one thread when anything else is done on the computer (such as mouse move). No, I can't get screenshots of the problem. Much as I try, the machine is locked up so hard when this happens that nothing works, not even the keyboard. It is still on no new work.

3) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1732) Posted 13 Sep 2022 by jm7 Post: Ok. We have a heisenbug. If I just sit looking at the computer waiting for it to happen, nothing happens. If I start using something with the mouse where I am doing actual work, I can see BOINC Manager shutting down and restarting the application in the background, and the computer gets horribly laggy, as in the mouse can freeze in place for a second. This does not happen with any of the other projects that I run under BOINC. I have captured the screenshots of prior, but cannot get a screenshot of what happens when it freezes because when I go to look, it is back to normal. I am about ready to give up. Please note that i am not the only person that has complained about this.

5) Questions and Answers : Windows : Will not queue more than about 4 work units per core despite set for 10 days of work (Message 1727) Posted 5 Sep 2022 by jm7 Post: Minor correction: Store at least X days - means that the computer coule be disconnected for up to that long. Store up to an additional Y days. Means that it is OK to store more on the computer, but not required.
6) Questions and Answers : Windows : Will not queue more than about 4 work units per core despite set for 10 days of work (Message 1726) Posted 5 Sep 2022 by jm7 Post: If I recall correctly, BOINC assumes that when you ask for 10 days worth of tasks that the computer will be disconnected from the internet for 10 days, and that any task with a deadline within that time is in danger of not meeting its deadline.

8) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1723) Posted 29 Aug 2022 by jm7 Post: It appears that the 80% of CPU usage is over all of the cores, not per core. Task Manager (a Windows System Utility) was reporting 100% CPU usage on all cores on the device (not just the cores that were allocated to BOINC). I had BOINC Manager running behind Task Manager so I could see some information in BOINC Manager as well. I watched Task Manager bounce between showing 100% CPU usage across all cores (every core running flat out) and less than 10% total across all cores (Which could be 2 cores running nearly full out, or a small load on each core - Task Manager isn't that specific). When BOINC Manager reported all tasks suspended, the CPU usage total was < 10%. When BOINC Manager reported all tasks running, Task Manager reported that total CPU usage was 100%. Something is clearly taking more CPUs that it is supposed to. Since disabling this project made the problem go away, evidenced points to this project as the culprit. I'm wondering if there is some library that you are using that might start extra threads under some conditions. I know that multithreaded applications are a pain to debug as they tend to generate heisenbugs. I didn't notice if you used a container of some sort. If so, it might be some interaction with the container.
9) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1721) Posted 27 Aug 2022 by jm7 Post: Both were set. Use at most 30% of CPUs and 80% of CPU time if I recall correctly. Task manager was reporting 100% of all CPUs used. which is what led me to believe that some project was starting more than 1 thread somehow.
10) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1718) Posted 25 Aug 2022 by jm7 Post: Let's recap what I saw in task manager. With BOINC CPU usage set at 30%, the CPU usage was spiking at 100%, BOINC would then suspend all the BOINC processes. The CPU usage would drop to less than 10%. BOINC would then unsuspend all the BOINC processes. The CPU usage would then spike to 100%. Rinse, repeat. Removing this project from the mix solved the problem. It may be an interaction between this project and windows, but in the end, it is this project that was causing the problem. I will help fix it, but blaming it on this hardware is a non-starter for me.

So, 20 cores? There are dozens of drivers. Anything in particular you are looking for?
13) Questions and Answers : Windows : Will not queue more than about 4 work units per core despite set for 10 days of work (Message 1700) Posted 15 Aug 2022 by jm7 Post: There are a couple of obvious possibilities. 1: The project does not have work to hand out right now. 2. If any task is in any danger of not being returned on time, BOINC will not fetch new tasks. This depends on settings and usage history.
14) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1698) Posted 12 Aug 2022 by jm7 Post: I have verified it is this project. I set it to no new work, and the problem is gone once the work for this project was completed. I will have to leave this project set to no new work until such a time as the problem is fixed. I need to be able to use my computer.
15) Questions and Answers : Windows : CPU utilization in Windows11 machine (Message 1693) Posted 11 Aug 2022 by jm7 Post: Similar problem. 14 core i7 windows 11 machine. I had CPUs to be used set to 30% CPU time at 60% and the CPU usage would bounce between a few percent and 100 a couple of times per second. I have stopped downloads from SiDock and the problem appears to have disappeared even with percent of CPUs at 80%. I have the machine set to run off of local preferences, and I have CPU and GPU set to run based on preferences.
16) Questions and Answers : Windows : Project fills CPU use to 100% although "Use at most xx% of CPU time" is set (Message 1686) Posted 10 Aug 2022 by jm7 Post: I have the same problem. I have a core i7 with 14 cores that are hyperthreaded. I keep marching the allowed number of CPUs lower and lower and lower. I am currently at 40% of cpus used, and this project is still spiking to 100% CPU usage. I believe that the process is creating multiple threads, each of which may take an entire CPU. And, no, it is not because of high CPU temperatures, it is because my mouse freezes up.
