  Go to task manager and see how many cores/threads you have in your CPU. See attached picture below for reference. Then in the "Intel MPI Local Parallel" tab, select (number of threads - 1) or (number of threads - 2) partitions. For example in the attached picture, there are 8 threads in my CPU, I usually use (8 - 1 = 7) or (8 - 2 = 6) partitions. You can select 8 partitions too but that'll slow your computer down for other activities. Hope that is wanted to know.
