[mvapich-discuss] Feature request: Configurable path to rsh command

[Moritz Schlarb]

Hello all,

I'm currently working on integrating MVAPICH2 into the LSF batch system.

To accomplish that, it would be of great help if I could set the exact 
rsh command to be used (which is currently hardcoded via #define) while 
configuring and/or executing mpirun_rsh (just like the selection between 
rsh and ssh).
If that is possible, I can simply use the LSF utility blaunch as a 
drop-in replacement for rsh which then uses the LSF daemons on the 
remote nodes for starting processes and communicating.

 From digging around in the sources for mpirun_rsh, I found it to be not 
much work to support this option, but I wanted to check with the 
developers if there was a possible inclusion of that feature in the main 
source tree.

Regards
