Could anyone please tell me what am I doing wrong on my 4 computers, since I am able to crunch only one task at a time on each of them?
Thank you

What is your CPU usage? Does BOINC say "4 CPUs"? Have you set your "Max # of threads for each task" preferences to 4? In which case it sounds like it should be working as designed.

Thank you


It looks like your preferences are set to use all available CPU cores for a single LLR task.
How many cores do you want used per task? You set this in your "edit preferences" page under the "job control and multi-threading" section. The second option ("Max # of threads per task") should be set to how many cores you want each task to use.

For example, your tasks on this host are currently running using 35 threads.
