[mpich-discuss] How to config mpiexec use rsh as default bootstrap?

[Pavan Balaji]

Setting the HYDRA_BOOTSTRAP and HYDRA_BOOTSTRAP_EXEC environment 
variables should work. What error are you seeing?

Alternatively, you can reconfigure MPICH2 as with 
--with-hydra-bss=rsh,ssh,fork,slurm,ll,lsf,sge,pbs,none,persist

This will reprioritize the launchers to give a higher priority to rsh.
