Hi,
I am trying to run simple mpirun commands (pretty much straight out of
mpirun man page) and getting a bit of error message. Here’s what I mean:
[tsakai_at_vixen Rmpi]$
[tsakai_at_vixen Rmpi]$ hostname

[tsakai_at_vixen Rmpi]$
[tsakai_at_vixen Rmpi]$ mpirun -H vixen -np 1 hostname

I am using two hosts: vixen and blitzen. It appears that when a machine other than
the one I am on it is specified via –H flag, I get “stty: standard input: Invalid argument”
message to stderr. It doesn’t seem to impeed the execution of the command (in
my example, hostname), though.
Can somebody please tell me what this means and what it takes to cure the problem?
Thank you.
