I'm using mpich2-1.3.2 to do the job.It seems the error is pointing to hydra?</div><div style="font-family:arial,sans-serif;font-size:14px">And I'm not sure about if hydra is installed in this cluster.So Maybe I need to install a same version hydra with mpich2 first?</div>
<div style="font-family:arial,sans-serif;font-size:14px">Also I'm confused how hydra is linked to mpich2-1.3.2 while installing them?</div><div style="font-family:arial,sans-serif;font-size:14px">Is there anyone who can give me some hint?</div>
