Subject: [OMPI users] Adjust the polling frequency in ompi ?
From: Hsing-bung Chen (hbchen_at_[hidden])
Date: 2009-06-23 17:42:56

Is this the right way to adjust the polling frequency in ompi?

in opal_progress.h
00141 OPAL_DECLSPEC void opal_progress_set_event_poll_rate(int

in opal_progress.c
Default setup in OpenMPI - tick rate = 10000
00106 /* set the event tick rate */
00107 opal_progress_set_event_poll_rate(10000);

What if I change it to the polling tick rate from 10000 to 100000

00106 /* set the event tick rate */
00107 opal_progress_set_event_poll_rate(100000);

Is this going to slow down the polling frequency ?
