Hi,<br><br>I have successfully built and run mpich 1.3.2 on our cluster. But since we rather use bprsh (rsh like) between nodes, I have to specify the bootstrap at mpiexec command line, like this:<br><br>mpiexec -bootstrap rsh -bootstrap-exec /usr/bin/bprsh<br>
<br>It works, but is there a way that I can make rsh as the default bootstrap in some config file, so I don't have to specify that on every mpiexec command?<br><br>I have tried to set HYDRA_BOOTSTRAP and HYDRA_BOOTSTRAP_EXEC environment variables, that didn't work.<br>
<br>Thank you!<br><br>Limin<br><br>
