[mpich-discuss] environment settings to select the preferred TCP netmask

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. -Jerry University of Houston _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
