In this podcast, the Radio Free HPC team looks at problems in the scientific software world. “There’s a bug in Python scripts that caused different results in identical routines run on different operating systems. As the guys discuss, it’s not a Python thing but a problem with the order in which files got read according to the operating system’s protocols. This impacts the sort order and thus the end results. The gang speculates on other causes of these types of problems and the fixes that should be employed.”
