[kepler-users] wrapping up, never ending workflow!

[Josep Maria Campanera Alsina]

Dear all,
I get a "wrapping up" message from an execution of a workflow that
coordinates the submission of computational chemistry jobs in a
cluster queue system. The workflow is based on the
TestJobFullCycle-SGE.xml provided by kepler itself, with some
variations. Find attached the mentioned workflows.

My workflow is a composite one. I'd like to execute sequentially
several tasks: 1st) submit jobs to a cluster, 2nd) collect all outputs
and save them locally and then 3rd) convert output files to other
formats. Since some tasks are designed for PN director and some for
SDF director the overall director is a PN director.

However, the task under the PN director (in charge of job submission)
never finishes tough the task is already completed and early shows the
message "wrapping up", so the execution never finish step 1st and 2nd
so the 3rd is never executed. Why PN director doesn't finish the task?
How Can I stop the director and allow the workflow to continue?

I think the problem is related to the PN director that as said in the
user manual "may refuse to automatically terminate because tokens are
always generated and available to downstream actors"! Here it comments
that "One can correct the problem by changing the firingCountLimit
parameter of the Constant actor to some finite value". If done that
but it continues with the same problem.

How can I overcome this? all comment will be appreciated!

Thanks in advance,

Josep Maria,
