This file contains a simple function to check the return code of MPI calls and abort the program if an error occured. The function prints an error message indicating where the error occured (using the provided log string).

The function check_mpi_return is the only function provided in this file.

shamcomm::check_mpi_return(mpicall, #mpicall)

Shortcut macro to check MPI return codes.

This macro is a shortcut to avoid having to write shamcomm::check_mpi_return(mpicall, #mpicall) everywhere in the code.

It expands to a call to shamcomm::check_mpi_return with the MPI return code and the name of the MPI function as arguments. This last argument is used to the MPI call that produced the error
