SAMPIK - Simple API for Message Passing Interoperability with Kokkos

About - WIP

SAMPIK is a work-in-progress API for enabling interoperability between Kokkos and Message Passing (e.g. MPI). It enables users to transparently communicate Kokkos views using MPI as a backedn.

Support features

• Point-to-point communications:
  • send and receive views

Assumptions:

• Views must be contiguous (but may be multi-dimensional)
• Views must reside on the HostSpace memory space

Planned features

See the Roadmap.

Quickstart

Pre-requisites

Before starting, make sure the following software is installed on your machine:

• CMake 3.16+
• C++20 conforming compiler
• Kokkos (packaged as a submodule of this repo)
• MPI implementation

Build

cmake -S . -B build <KOKKOS_FLAGS...>
cmake --build build

Run

Run the test program:

cmake --build build --target send_recv
mpirun -n 2 build/tests/send_recv

Or directly using ctest:

cmake --build build --target test
