Hello all:

I am currently using mpich3.1.3. I need help in tuning the environment

settings to select the prefferred TCP netmask  or network. The variables

MPICH_TCP_NETMASK 

MPICH_NETMASK 

MPIR_CVAR_NEMESIS_TCP_NETMASK

don’t seem to the working

Also, how can I tune the eager threshhold. Intel MPI uses I_MPI_THRESHOLD

for doing this. Thanks for all the help advance.
