Summary | Modern parallel supercomputers are predominantly programmed using the Message-Passing Interface (MPI) library. Learning the basic MPI syntax and writing medium-scale programs is relatively straightforward, but many issues only arise when tackling large-scale problems on thousands of processes. Typical issues include deadlock, poor scalability or inefficient file IO.
There are two basic ways to address these issues. The fundamental MPI calls can be used in more sophisticated ways, which requires an in-depth understanding of the finer details of the MPI standard and its implementation in real libraries. Alternatively, different approaches can be used which employ advanced MPI functionality or which exploit the shared-memory nature of modern multicore compute nodes. Before any correctness or performance issues can be addressed they must first be diagnosed, so knowledge of parallel profiling and debugging is essential. |
