Hi Xianbei,
<div><br>
</div>
<div>Have a look at the nekbmpi script and modify to match the job submission</div>
<div>procedure on your cluster.</div>

<div>Hi,all:<br>
I have just built a small cluster of computers, based on mpich.I have tested the capability of this cluster, each node can be called freely. Now I want to do my simulation in it, however, I don't know how to run Nek. As known, on only 1 computer, one can
do like this:<br>
nekmpi XXX X <br>
or<br>
nekbmpi XXX X<br>
while this is not the case in the cluster! I believe most of you have tried this, I'll appreciate if anyone can give me some advice.<br>
Best regards<br>
Xianbei <br>
