mpi-hs-binary

Release

MPI (the Message Passinag Interface) is a widely used standard for distributed-memory programming on HPC (High Performance Computing) systems. MPI allows exchanging data (_messages_) between programs running in parallel. There are several high-quality open source MPI implementations (e.g. MPICH, MVAPICH, OpenMPI) as well as a variety of closed-source implementations. These libraries can typically make use of high-bandwidth low-latency communication hardware such as InfiniBand. This library mpi-hs provides Haskell bindings for MPI. It is based on ideas taken from [haskell-mpi](https:/github.combjpop/haskell-mpi), [Boost.MPI](https:/www.boost.orgdoclibs1_64_0dochtml/mpi.html) for C++, and MPI for Python. mpi-hs provides two API levels: A low-level API gives rather direct access to the actual MPI API, apart from certain "reasonable" mappings from C to Haskell (e.g. output arguments that are in C stored via a pointer are in Haskell regular return values). A high-level API simplifies exchanging arbitrary values that can be serialized. Note that the automated builds on [Hackage](http://hackage.haskell.org) will currently always fail since no system MPI library is present there. However, builds on [Stackage](https://www.stackage.org) should succeed -- if not, there is an error in this package.

Documentation

mpi-hs-binary

MPI bindings for Haskell

Overview

This is a companion package to mpi-hs. Read the documentation there.

This package mpi-hs-binary provides a high-level interface based on Data.Binary in the binary package. This is a separate package to reduce dependencies for mpi-hs. Note that mpi-hs has a similar high-level interface based on Data.Storable already built in.

Running the tests

There is one test case provided in tests:

stack build --test --no-run-tests
mpiexec -n 3 stack exec -- $(stack path --dist-dir)/build/mpi-test-binary/mpi-test-binary
