5.2 Exascale MPI

The Exascale MPI (Message Passing Interface) project consists of team members from Argonne National Laboratory. The project focuses on developing a production-ready, high-performance MPI implementation that scales to the largest supercomputers in the world. One particular challenge for the Exascale MPI project is a continuous influx of new contributors within the project. These new contributors are expected to already have technical expertise with MPI or learn these skills on-the-fly as needed by the job. While the team does provide some mentoring to new members, limited resources require that newcomers be fairly independent and proactive when it comes to learning the basic technical aspects of MPI.

The Exascale MPI team worked with a facilitator to implement the PSIP process. Through the documentation of current practices, the need to improve the project’s onboarding processes was identified. Both the Exascale MPI team and the facilitator agreed to work on a PSIP cycle focused around improving the training for team contributors. This would take the form of a single destination resource containing all the required training material that could be provided to new team members during the onboarding process.

Once the overall goal was identified, the Exascale MPI team, together with the facilitator, identified key aspects of a satisfactory solution. These aspects included the need for:A central “repository” for all training material, relevant to the Exascale MPI team.
