2022 summer school on informatics
Hybrid and asynchronous high-performance programming
Contents
Main subject
The main subject of this school is related to hybrid parallel programming (MPI+OpenMP), with the use of asynchronism to enhance the overall computing performance. Based on HPC (High-Performance Computing), the target courses aim at teaching efficient asynchronous algorithms for current generations of supercomputers.
Context
Nowadays, the number of computing units has dramatically increased in supercomputer architectures. Even if the overall performance of such machines is still growing, exploiting the corresponding units becomes more and more complex. Indeed, exposing efficient parallelism on such a large number of cores is already tedious. One possible solution is to mix multiple parallel programming models like MPI and OpenMP to benefit from advantages of both worlds (performance and memory consumption). However, various approaches exist to make such hybrid applications efficient: coarse-grain parallelism, correct resource placement, interoperability between different runtimes, asynchronous computing…
Goals
In this context, the summer school presents best practices to mix multiple programming models focusing on asynchronous computing and communications with MPI and OpenMP. This approach reduces concurrent memory accesses overhead, impact of network communications… Hands-on sessions will illustrate the main concepts on a target supercomputer.
