Detailed Description

Doctest-based unit tests for DNDS MPI wrapper functionality.

Run under mpirun with varying rank counts (1, 2, 4). Covers DNDS::MPIInfo, collective operations (Allreduce, Scan, Allgather, Bcast, Barrier, Alltoall), MPI type mapping, and CommStrategy.

See also: DNDS Core Unit Tests for the full test-suite overview.

Test:: MPIInfo, Allreduce, Scan, Allgather, Bcast, Barrier, Alltoall, BasicType_To_MPIIntType, CommStrategy.
