Cadence distributed processing with SKILL

TaherKotb

Hello,

I have a skill code that i wish to run in distributed mode. The distributed processing user guide eloborates the setup of distributed mode option with OCEAN commands. does the same setup apply for skill code?. If not, is there any other option which could speed up the code runtime?.

Thanks in advance

Best Regards

Taher

    Output of the last command is nil. Is there something missing ? 

    It looks like you are assuming ipcBeginProcess() starts a SKILL interpreter to read a file. 

    That is not what it does.

    ipcBeginProcess() starts /bin/sh, which executes the UNIX shell command you give it. 

     

    So you told /bin/sh to run "/home/Work_IC6/test.sh", and the result is that the shell tried to run that as a shell script.

    Since the text of test.sh is actually SKILL code, the UNIX shell cannot understand it, and you get an error message on standard error, but no output on standard output, which is why ipcReadProcess() returned nil: there was no (standard) output.

    What you are trying to do is something like:

        ipcBeginProcess("skill /home/Work_IC6/test.sh")

    which runs a standalone SKILL interpreter to interpret the script.

    You can also run virtuoso this way, either using -replay, or echoing some SKILL code to it through a pipe.
