[Difx-users] WARNING Could not open monitoring socket

[Stuart Weston]

I have two servers, they both have 2 x CPU ( 6 cores, hyperthreaded). So
potentially I have 24 cores and 48 threads.



mpirun starts mpifxcorr on both servers, but we get the “WARNING Could not
open monitoring socket ! Aborting message receive thread” on the master ?
The processes seem to sit there and do nothing, nothing more in errmon2.



If I change the machines file I can run the same correlation on each server
individually to completion, so DiFX has to be good.

Note our network we have been asked to use a different multicast address,
so in DIFXHOME/setup.bash I have set:


DIFX_MESSAGE_GROUP=239.253.253.90

DIFX_BINARY_GROUP=239.253.253.90




Any ideas ?
