POPython - multithreading / multiprocessing
text
Body
copied!<p><strong>Background</strong><br /> I have a collection of Python scripts used to build and execute Verilog-AMS tesbenches. The overall design was built with threading in mind, as each major test case is its own testbench and I have all of the supporting files / data output separate for each instance. The only shared items will be the launcher script and my data extraction script. The problem that I'm faced with is that my Verilog-AMS simulator does not natively support multithreading and for my test cases it takes a substantial amount of time to complete.</p> <p><strong>Problem</strong><br /> The machine I'm running this on has 32GiB of RAM and 8 "cores" available for me to use and I may be able to access a machine with 32. I would like to take advantage of the available computing power and execute the simulations simultaneously. What would be the best approach?</p> <p>I currently use <code>subprocess.call</code> to execute my simulation. I would like to execute up to <code>n</code> commands at once, with each one executing on a separate thread / as a separate process. Once a simulation has completed, the next one in the queue (if one exists) would execute.</p> <p>I'm pretty new to Python and haven't really written a threaded application. I would like some advice on how I should proceed. I saw <a href="https://stackoverflow.com/questions/1190206/threading-in-python">this</a> question, and from that I think the <code>multiprocessing</code> module may be better suited to my needs.</p> <p>What do you all recommend?</p>
