- Not cpuset
- Not the -n argument to mpicasa
- OMP_NUM_THREADS but it seems to only increase the thread count if is is greater than 1.
- OMP_NUM_THREADS=1 max threads seen for a python process is 10
- OMP_NUM_THREADS=2 max threads seen for a python process is 11
- OMP_NUM_THREADS=4 max threads seen for a python process is 15
- OMP_NUM_THREADS=8 max threads seen for a python process is 27
- OMP_NUM_THREADS=16 max threads seen for a python process is 51
QUESTION: does the number of threads per process vary based on cpuset size?
