In abusive MPI communication patterns, sending a UDP ping only once a second may not be sufficient -- all the UDP pings may be dropped. So increase the frequency of the pings to every quarter second, and allow more total pings to be sent. Total timeout time is still the same (10 seconds) -- we'll just now try 40 times (i.e., once every quarter second) as opposed to 10 times (i.e., once a second). Testing has shown that this frequency allows the connectivity checker to always succeed even in the many-to-one abusive communication patterns. cmr=v1.8.2:reviewer=dgoodell This commit was SVN r31602. |
