[molpro-user] weird issue with MOLPRO 2010.1 binaries

[Kirk Peterson]

Hi Jan,

I agree it's strange that it works interactively but not through PBS.  Perhaps to put this rsh vs. ssh stuff to rest you could try the following:

1)  put the following in your .cshrc file so that it is set on all your nodes:   setenv RSHCOMMAND /usr/bin/ssh

2)  if that doesn't help, just make a soft link (on all nodes) that points /usr/bin/rsh to /usr/bin/ssh

Manhui:  why is rsh the default and not ssh for the parallel binaries?  No one uses rsh any more.....

regards,

Kirk

It's when I try to run a Torque/PBS job (again, ON A SINGLE NOTE) that I get this error message. I looked again and again at the environments in both cases and do not understand what is different.
