    Threading Or Other Suggestions?!?

    Hello NG,

    I have a wxPython application that does a lot of things. One of them,
    in particular, I have doubts on how to implement it. Essentially, this part
    of my application calls an external executable (an oil reservoir
    simulator). What I would like to do, is to give the user the possibility to
    run more than 1 simulation at the same time. This means:

    1) Writing the executable "data file" needed by the simulator
    2) Run the executable file (and wait until completion)
    3) Examine the simulation results

    For this, I was thinking about threads... does anyone have other/better
    suggestion(s)? Does anyone see any difficulty/memory problems in using
    threads?

    Thanks to you all for every suggestion.

    Andrea.

      If you're not on Windows, this will be much easier with multiple
      processes.

          You could also use os.spawnl to launch it in a separate process.

              Yes. Threads are used to run multiple parts of your own program. To run
              another program, you need to launch a new process.

              You can still monitor it.
