We describe our eorts to speed up the computational uid dynamics (CFD) application code Strand2D via the parallel multigrid reduction in time (MGRIT) software library XBraid. The need for parallel-in-time approaches, such as MGRIT, is being driven by current trends in computer architectures where performance improvements are coming from greater parallelism, not faster clock speeds. This leads to a bottleneck for sequential time integration methods, such as those used in Strand2D, because they… CONTINUE READING
