Cadence distributed processing with SKILL

You can run as many "distributed" SKILL processes as you like:

rsh $remoteHost1 skill myfile1.il &

rsh $remoteHost2 skill myfile2.il &

  .

  .

  .

If you use LSF,

bsub -q myQueue skill myfile1.il

bsub -q myQueue skill myfile2.il

.

.

.

Hello, 

Thanks for your reply. Actually, what i want is to find a way in which one process(procedure) can breakdown into sub-processes and run on distributed machines. can this be done?

Thanks again

Best Regards 

YES: use ipcSkillProcess().

Thanks for your help, i executed 'ps aux' command to see the available processes, however didn't find my prcocess in the list.

I am sorry, my knowledge in skill is limited. Please bare with me. 

Here is the code:

procedure( test() printf("Testing\n") ) ; wrote it in test.sh file

svnCmd = sprintf(nil "/home/Work_IC6/test.sh" )

cid = ipcBeginProcess( svnCmd )

ipcWait(cid) 

ipcReadProcess(cid)

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

Thanks for your great help.

Best Regards

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.
