MPE_Init_log(4) MPE MPE_Init_log(4)
MPE_Init_log - Initialize the logging of events.
int MPE_Init_log( void )
This routine must be called before any of the other MPE logging
routines. It is a collective call over 'MPI_COMM_WORLD'.
MPE_Init_log() & MPE_Finish_log() are NOT needed when liblmpe.a is
linked because MPI_Init() would have called MPE_Init_log() already.
liblmpe.a will be included in the link path if either "mpicc
-mpe=mpilog" or "mpecc -mpilog" is used in the link step.
This function is threadsafe, but MPE_Init_log() is expected to be
called on only one thread in each process. This thread will be
labelled as main thread.
Always return MPE_LOG_OK.
