### What if I want to communicate between teams myself? ###
To get access to the original MPI function, prefix it with a P. For example, MPI_Send becomes PMPI_Send.
If you wish to map between original rank numbers, know how many teams there are, perform a global barrier, etc. take a look at the Rank.h file.
It has access to all the data internal to teaMPI. To use the functions declared in it, simply `#include "Rank.h"` and add the path to `teampi/lib` to the compilation `-I` flags.
### Who do I talk to? ###
