Workshop "Parallel-in-Time Integration Schemes", June 3rd at the Institute of Computational Science, USI Lugano

With high performance computing systems featuring growing number of nodes, efficient strategies to parallelize all parts of a program become increasingly important. While parallelization in space by domain decomposition is already widely used, for a fixed spatial resolution this approach scales well only up to some critical number of processors beyond which the sub-domains are too small and communication becomes the bottleneck. Parallel-in-time Integration schemes provide an additional direction of parallelization, potentially allowing to reduce total execution time of parallel programs below the point where a pure spatial parallelization saturates. One algorithm from this field that received a lot of attention over the past years is "Parareal", which has been successfully applied to a broad range of problems. The workshop is dedicated to the presentation of recent developments, advances and applications of "Parareal".
