5.11 MP_STATISTICS
If MP_STATISTICS is set to yes, statistics are collected. However, these statistics are written only when a call is made to mp_statistics_write, which takes a pointer to a file descriptor as its sole argument. These statistics can be zeroed out with a call to mp_statistics_zero. This can be used with calls to mp_statistics_write to determine the communication statistics in different portions of the user application. These statistics are useful for determining if there are excessive packet retransmits, in addition to giving the total number of packets, messages, and data sent or received. The late arrivals are useful in determining how often a receive was posted before the matching message arrived. Early arrivals indicate how often a message is received before the posting of the matching receive.
MP_STATISTICS take the values yes and print. If the value is set to print, the statistics are printed for each task in the job at MPI_FINALIZE. If you set MP_STATISTICS to print, you should also set MP_LABELIO to yes so you know which task each line of output came from.
The following is a sample output of the statistics.
