Hi Madhavi,<br>
<br>
You want the workflow kar file to be executed on one node of PBS
or schedule actors among multiple nodes of PBS?<br>
<br>
The current job submission support in Kepler is mainly for
submitting separate executables to a cluster, not a workflow. Yet I
think it will also work to use kepler.sh as executable to execute
your workflow on one node of PBS. But you need install Kepler on
your cluster first. I don't know there are simpler ways.<br>
<br>
If you want to schedule actors among multiple nodes of PBS, you
can try Kepler master-slave module
(<a class="moz-txt-link-freetext" href="https://kepler-project.org/developers/incubation/distributed-ms">https://kepler-project.org/developers/incubation/distributed-ms</a>) in
Kepler. You need add either module master-slave-2.0
(<a class="moz-txt-link-freetext" href="https://code.kepler-project.org/code/kepler/releases/release-branches/master-slave-2.0/">https://code.kepler-project.org/code/kepler/releases/release-branches/master-slave-2.0/</a>)
or module master-slave in trunk
(<a class="moz-txt-link-freetext" href="https://code.kepler-project.org/code/kepler/trunk/modules/master-slave/">https://code.kepler-project.org/code/kepler/trunk/modules/master-slave/</a>)
into your suite. Then you need to wrap your actors to-be-distributed
in DistributedCompositeActor in master-slave module. You also need
start slave started on each PBS node so that this node can accept
sub-workflow input from master. <br>
