screen with ocean

vikram1977
hello i invoke an ocean script from within a bash file many times (in a for loop) i use screen to detach my running program when i reattach the screen program, i figure out that ocean was run only one time and dosn't carry on can you please help to find what make the main loop don't work best regards

  • I've not really used the screen command, but having taken a quick look at it, I think you'll need to describe more about the specifics of what you're doing so that there's a chance somebody might be able to comprehend and answer your question.

  •  Did you try first with nohup ?

    Also a warning, I suppose you run  ocean for different Hierarchy. Indeed, if you run spectre for a same design, it will overwrite the result directory (psf) so you will get only the last simulation.

    NB : if you want a clearer answer, ask a clear/detailed question.

  • Thank you Andrew, ebecheto sorry about the ambiguity i found the source of the probleme the probleme actually is not screen but the ocean script when you run the ocean script with the -nograph option , you have to explicitly add an exit() at the end of the ocean script, otherwise it will hang that what was happenning with me.

    For example, while using OCEAN with the -nograph option, your oceanScript.ocn file must have an exit() statement at the end. Otherwise, OCEAN hangs. The reason for this is that when the workbench is started in the non-graphical mode, it does not redirect standard I/O as it normally does; instead, it lets the SKILL human interface (HI) handle the standard I/O. HI expects an explicit exit() statement at the end of the OCEAN script and OCEAN exits only when it detects an exit() at EOF.

  •  for clarification that was the context of the question

    foreach myvariable ("case1" "case2" "case3")

    ocean -nograph < oeanScript.ocn

    end

    the problem was that the the ocean script was invoked only for case1, and the cause was that ocean hanged since there was no exit() statement at the end of the oceanScript.ocn file

  • sorray again waht do you mean by nohup, i can't find it on ocean manual regards
