The challenge with distributed applications is that most of the tools and packages that we can use for single-process applications lose much of their power when dealing with multiple processes, especially when these processes run on different computers.

Debugging and profiling distributed applications written in C, C++, and Fortran can be done with tools such as Intel VTune, Allinea MAP, and DDT. Unfortunately, Python developers are left with very few or no options for the time being.  Learn more about these challenges in this guide: Testing and Debugging Distributed Applications
