Quicker correction: This is all of the memory for 4 processes out of the
160 aggregated together (because only 4 were running on the node the memory
logger was launched on).
The memory logger can aggregate across all processes (even across nodes)
but only when run using our batch job system (PBS) which wasn't being
utilized for these runs....
