I've also been just looking at this for the past few days. What I came
up with is a small script psm_shctx

This is your problem: it should be something like drwxrwxrwt. It might
depend on the distribution, f.e. the followi

you more.

Not good to reply to oneself, but I've looked at the archives and
realized that 'uname -X' comes from a message of the OP. My guess is
that the same source directory was

f restricting ports used by OpenMPI will help. The firewall can stay
on, but it should be configured to open a range of ports used by
OpenMPI.

/etc/securetty in order to allow
orterun to access the machines or is the rsh/rlogin entry

If running commands on remote nodes with rsh is already working (as
you showed in the first message), there shouldn't be any additional
settings needed.
