MPIEXEC IS USING SSH AND IS GENERATING SSH MESSAGES

[Francois Courteille]

Hi there,

mpiexec looks a nice tool.

I have ported it (release 0.74)to one of our small LINUX  clusters.

I have a question regarding its usage.

Trying to run a small test i'm getting a lot of ssh messages, like below :

mpiexec -n 1 /tmp/test_fc
generating ssh file /tmp/.ssh/id_dsa ...
Generating public/private dsa key pair.
open /tmp/.ssh/id_dsa failed: No such file or directory.
Saving the key failed: /tmp/.ssh/id_dsa.
generating ssh file /tmp/.ssh/identity ...
Generating public/private rsa1 key pair.
open /tmp/.ssh/identity failed: No such file or directory.
Saving the key failed: /tmp/.ssh/identity.
generating ssh file /tmp/.ssh/id_rsa ...
Generating public/private rsa key pair.
open /tmp/.ssh/id_rsa failed: No such file or directory.
Saving the key failed: /tmp/.ssh/id_rsa.
cat: /tmp/.ssh/id_dsa.pub: No such file or directory
touch /tmp/.ssh/authorized_keys2
touch: creating `/tmp/.ssh/authorized_keys2': No such file or directory
chmod 700 /tmp/.ssh/authorized_keys2
chmod: failed to get attributes of `/tmp/.ssh/authorized_keys2': No such file or
 directory
grep: /tmp/.ssh/authorized_keys2: No such file or directory
adding id to ssh file /tmp/.ssh/authorized_keys2
/tmp/.ssh/authorized_keys2: No such file or directory.

What is the fix to avoid those messages ?

Thank you in advance,

with best regards,

Francois Courteille
