     38When running under common batch systems, the files are named 
     39JOB_ID.HOST.PID.memlog, and when running under the BG/Q CNK, the process's rank 
     40is used instead of the node-local PID. 
     41 
    3842Note that te peak memory usage is determined by monitoring the processes's 
    3943maximum resident set size, not just the total allocated heap memory.
