Writing Scalable Parallel Applications with MPI

Learning the basic MPI syntax and writing small example programs can be relatively straightforward, but many questions only arise when you first tackle a large-scale parallel application. Typical topics include how best to avoid deadlock, overlapping communication and calculation, understanding performance, debugging strategies or parallel IO.

This hands-on course is an opportunity to learn how best to use MPI based on the experiences of the ARCHER CSE team at EPCC.

Rather than covering advanced MPI functions, it will focus on the practicalities of using MPI effectively for large-scale parallel scientific applications. It will also cover the most common mistakes and misconceptions that occur in MPI programs.
