<div>Hello,<br>
<br>
I'd suggest trying three things.<br>
<br>
First of all - does your cluster allow running interactive jobs?
If yes, than you should create an interactive job to run
/bin/bash. I'm not familiar with PBS, but in SGE/OGE if you print
cluster queues with "qstat -f" you'll see "I" in column qtype
which means that given queue allows running interactive jobs.
Using bash you should be able to run top on given node without SSH
access.<br>
<br>
Regardless of success or failure you should be able to look at
nodes statistics using "qhost" command. You should see at lease
what is the current load, memory usage and swap usage. In SGE/OGE
there's a switch "-j" to qhost which will also show you what jobs
are currently running on each node. It's necessary to be able to
see load of machine interactively instead of view at some point of
time. <br>
<br>
The last concept is to prepare a job to run at the same time on
the same node as Wien2K, consisting of several <br>
"ps auxww | grep ogando >> ${HOME}/ps.output; sleep 2" <br>
commands. It will give you some information on what's going on.
Think of it as non-interactive top stored in text file.<br>
<br>
<br>
Best regards,<br>
<br>
Pawel Lesniak<br>

<div> Hi,<br>
<br>
</div>
I can not access the nodes. SSH among them
is forbidden ! We have to ask the
administrators for anything !! It is the hell
!!<br>
</div>
<div> Of course, only the PBS jobs can
"travel" among the nodes.<br>
