[mvapich-discuss] MVAPICH2 Installation / Configuration help

[Jaidev Sridhar]

Hi Alex,

mpispawn is a utility that mpirun_rsh starts on all nodes. 

Can you check if 
a) mpispawn is installed in $MVAPICH2_HOME/bin (i.e., same directory as
mpirun_rsh) on all nodes and
b) $PATH (including $MVAPICH2_HOME/bin) is being propagated correctly
