Unix systems (Linux and MacOS)
- A shared library MPI installation for C (supporting MPI standard 3.0), and
- A C compiler available via the
mpicccommand: this is required as part of the build process to determine the necessary type definitions and constants.
This has been tested with:
MPI.jl requires the Microsoft MPI (MS-MPI) runtime to be installed.
The MPI.jl package can be installed via
add MPI in the Julia package manager.
The build script will attempt to find the shared library and constants: this can be controlled with the optional environment variables:
JULIA_MPI_PATH: the top-level installation directory of MPI.
JULIA_MPI_LIBRARY: the path of the MPI shared library.
JULIA_MPI_LIBRARY_PATH: the directory containing the MPI library files.
JULIA_MPI_INCLUDE_PATH: the directory containing the MPI header files.
JULIA_MPI_CFLAGS: C flags passed to the constant generation build (default:
JULIA_MPICC: MPI C compiler (default:
JULIA_MPIEXEC: MPI startup command (default:
If your MPI installation changes (e.g. it is upgraded by the system, or you switch libraries), you will need to re-run
build MPI at the package prompt.
