Module environment 

Process-wide MPI environment: initialization, finalization and the Universe handle. Mirrors mpi::environment in rsmpi.

Structs

Universe

Represents the initialized MPI environment.

Enums

Threading

The level of thread support, matching the four MPI constants (MPI_THREAD_SINGLE, …, MPI_THREAD_MULTIPLE).

Functions

initialize

Initialize the MPI environment with the default (maximal) thread support, returning the Universe handle. Equivalent to rsmpi’s crate::initialize.

initialize_with_threading

Initialize the MPI environment requesting a given Threading level. Returns the Universe and the level actually provided, mirroring rsmpi’s crate::initialize_with_threading.

library_version

A human-readable description of the MPI library (MPI_Get_library_version).

processor_name

A name identifying the calling processor (MPI_Get_processor_name).

threading_support

The thread-support level provided by the running environment (MPI_Query_thread).

time

Monotonic time in seconds since an arbitrary fixed point (MPI_Wtime).

time_resolution

The resolution of time in seconds (MPI_Wtick).

version

The supported MPI standard version as (major, minor) (MPI_Get_version).
