Intel oneAPI MPI Library

This is a flake to use Intel oneAPI MPI Library.

Requirements

A working installation of Nix on Linux x86_64

Usage

1. Clone this repository and run:

   cd intel-mpi-nix
   nix develop

2. Compile the provided Hello World example with:

   mpicc -o hello hello.c

3. Run the example with:

   mpirun ./hello

Alternatively, you can run the development environment directly from Github with:

nix develop github:waltermoreira/intel-mpi-nix

and use the environment to compile your own sources.

Composing with other flakes

Code that compiles using other MPI implementations (for example, nixpkgs.mpich) can use this flake as a drop-in replacement.

1. Add the input intel-mpi.url = "github:Nixify-Technology/intel-mpi-nix" to your flake.
2. Instantiate the default package with:

   mpi = intel-mpi.packages.${system}.default;
   

3. Use the package mpi as a replacement for mpich or any other implementation.

To Do

• Support ARM architecture.
