Charm++ parallel programming system

[Jeff Hammond <jeff.science AT gmail.com>]

Many years ago, I figured out how this stuff worked with help from Abhinav Bhatele, Mike Stewart of NERSC and Dave Strenski of Cray.  The results are captured here:

https://github.com/jeffhammond/HPCInfo/wiki/Cray#topology
https://github.com/jeffhammond/HPCInfo/tree/master/topology

I'm not sure how helpful this will be.  The XE/Gemini topology info was straightforward and I found the header files to be sufficient to understand what the RCA library was doing.

Since Charm uses the RCA library (cf. util/topomanager/CrayNid.c) I was wondering if anyone there had documentation on using the library. I’m aware of the comments in Cray’s rca_lib.h, which describe each function, but we have a user who has requested a more detailed description.
