My task is to make a flask app that will open an html page where a JS script would poll the server for info about the game and double the visualization from terminal to the web page. This tutorial walks through a Python example of running a parallel workload using Batch. The child process will only inherit those resources necessary to run the process object's run() method. Another option is to place the conda environments in a non-system folder. The PBS resource request #PBS -l select=1:ncpus=1 signals to the scheduler how many nodes and cpus you want your job to run with.
