Hello, I apologize in advance if this is the wrong forum for this question, but I recently read that PyFR is a Gordon Bell finalist for having run on the Titan machine. I also recall a year or so ago hearing about significant difficulties in running Python at large scale on supercomputers. The specific issue I recall has to do with Python's module import doing filesystem searches from all compute nodes at once, stressing the filesystem. Have issues like this been resolved in a general sense, or via workarounds ? What is the current outlook for others to develop Python code that can scale on leadership-class supercomputers ? Anyway, congratulations and thank you in advance for any clarifications you can provide.
