I'm attempting to set up a new submit host with a different OS
(major) version than the compute cluster. Should this be doable?<br>
<br>
I have an OpenMPI app I can submit, using sbatch and qsub, from
a cluster node and it runs fine. However, when I submit from the
new host it fails. Initially I didn't have the compiler or
OpenMPI even installed on the new submit host which resulted in
missing library errors. So I installed them even though they'll
never be used on the new host. Now I'm fighting OpenMPI errors.
It seems like incorrect settings or information are being
gathered from the new submit host and then applied on the
compute nodes. I don't care about the environment of the new
submit host at all though. I just want it to be able to launch
jobs with apps that have been built on the cluster. Does a
submit host have to be the same OS as a compute cluster?<br
