FWIW, I have my private notes on process and datatype -related structs. https://rivis.github.io/doc/openmpi/openmpi-source-reading.en.xhtml
They are created by my hands with the help of Autodia. http://www.aarontrevena.co.uk/opensource/autodia/ > I want to know if there is “class diagram” for OpenMPI code base that shows > existing classes and dependencies/associations. Are there any available tools > to extract and visualize this information. Thanks, KAWASHIMA Takahiro
