I am also experiencing the stalling of N-Body simulation tasks. When I reboot my Win11 HP laptop with 16M of memory and a 1TB SSD it will run for maybe 5 min - 30 min and then it appears to stall and the number in the progress column then never changes. I can wait hours and it never changes. I resolve the "Progress" issue temporarily by
1) Restarting my computer
2) Closing and opening the BIONIC Manager Application
OR
3) I will go to Activity on the menu bar and select "Suspend" for the CPU section. All tasks then report a status of "Suspended - user request (8 CPUs)". When I select Activity on the menu bar and select "Run always" or "Run based on preferences", the numbers in the progress column starts counting up again. If I wait again, anywhere from the 5 min - 30 min the N-Body Simulation task stalls and ceases to progress.
4) When I go into Windows task manager and look at the BIONIC manager process percentage when the processing stops, the CPU % use is zero (0) or maybe .1%. Once I "Suspend" the task and select "Run based on preferences" under Activity on the menu bar, the task starts counting up and the CPU usage for Bionic manager returns to 40% usage (Which is what I have my preferences set for).

It almost seems like for whatever reason 1) A setting needs to be changed somewhere, 2) There is some sort of a memory leak in the application, or 3) The system runs out of resources and can't continue until a reboot, the BONIC Manager restarts, or the task is suspended and re-enabled.

Does any of this make sense?

I have a question and possibly a problem with some tasks stalling

I am running an AMD Ryzen 7 5700U (16 cores supposedly) with Radeon Graphics CPU.

Question
Almost always, my system processes with a status of "Running (0.903 CPUs + 1 AMD/ATI GPU (device 0 or device 1))"
Does the Running 0.903 CPUs mean it is running 90.3% of all CPUs or 90.3% of one CPU?

Problem
At the same time, I have a task which reports 14.531% complete and the status is "Running (12 CPUs)". However, this task is stalled and doesn't process (it is an N-Body Sim task). I have had several task like this occur over the past couple of weeks. The latest one had a deadline date of 4/19, but as of today (4/20) the progress remains frozen at 14.531% and the status is running.

When I looked for the N-Body setting to check or uncheck (don't remember which) the setting doesn't show up. I don't know why the "Running (12 CPUs)" task stalls. Any answers or suggestions would be greatly appreciated. Thank you.[/img]
