The viper firewall settings have not changed in a long time, before
Nika and the Swift team got accounts on it.<br>
<br>
Here are the settings:<br>
TCP Ports: 50000:60000 8080 8443<br>
UDP Ports: 50000:60000<br>
<br>
Now, just to double check if it is the firewall, I have disabled the
firewall temporarily until we know for sure it is the firewall that is
causing the trouble. <br>

PS: MolDyn with 244 mol was running out of memory on machines with 0.5
or 1GB of memory... viper has 2GB, and it seems to have held up fine
through the various large runs we made... so if you want to switch to a
different machine, just make sure to have at least 2GB of memory so you
can give the JVM the maximum memory of 1.5GB.<br>

<pre wrap="">sounds like viper had firewall configuration changed recently. viper
sysadmin needs to help debug basic job submission with simple globus tools
before that machine is worth using again.

Not sure what else has changed on viper? It used to be a very good submit

You
might want to set the TCP_PORT_RANGE (I am not sure this is the
exact
environment variable, but something like that) to be between 50K and
60K
ports
to ensure that GT4 uses one of these open ports.

<pre wrap="">The same. You can check the job's status in its log on viper in
~nefedova/alamines/MolDyn-244-loops-20070917-1356-h95gxij8.log.
The job is still runnning (i.e. hanging) with the same symptom as
before:
the first jobs is done and then nothing else gets submitted (the
submit host
doesn't receive any notification that the job has finished).
