[kepler-dev] Query regarding 'GenericJobLauncher' actor

[Ravi Kumar]

Hello Daniel,

Thanks a lot for quick response. I tried to create workflow with this approach that you mentioned in this thread, connecting output port "success" to next "GenericJobLauncher".  As per my understanding "success" port is a boolean flag to indicate if job launch was successful. But we want to execute second process only when first process completes successfully. I am not able to add this dependency with second "GenericJobLauncher". 
Can you please let me know whether we can put this dependency with subsequent "GenericJobLauncher" or not? If yes how?

There is a output port "exitcode" provided with "GenericJobLauncher". As per documentation it says, If the exit code is 0, the command was performed successfully. But I didn't get any output on this "output" port even after job completes successfully.  So I am not able to use this output(exitcode) port as trigger to next Actor.

For your information: I am using -Kepler 2.3 on Linux machine(Rad Hat 6.1) with 'PBS' scheduler. 
Thanks in advance.


Regards,
Ravi

Hi Ravi,

The output port "success" can be used to trigger another GenericJobLauncher or any other actor. I've attached a workflow demonstrating this with two GenericJobLauncher actors.

Now I want to use "GenericJobLauncher" actor instead of Exec so that each process can be run on different node on grid. In my original workflow 'exitCode'  output port of first 'Exec' Actor  is connected to 'trigger' input port of next 'Exec' actor. But with 'GenericJobLauncher' actor there is no input port like trigger, also 'exitCode' output port is commented in code and it's not working.
