Detailed Description
The sc library provides several mechanisms to work with MPI.
The most important one is a wrapper that looks the same to the user whether MPI has been configured or not. This allows to use MPI commands in code without protecting #defines.
In addition, we provide MPI reduce, allreduce replacements with reproducible associativity as well as an allgather replacement.
