targetDART - dynamically adaptive and reactive distribution of tasks on heterogeneous exascale architectures

targetDART develops reactive and adaptive dynamic load-balancing mechanisms to mitigate variations in computational load and performance on heterogeneous exascale systems. targetDART builds on the preceeding Chameleon project, which has realised dynamic task offloading for MPI+OpenMP applications on CPU-only systems, and extends the load-balancing approach towards dynamic scheduling to (and between) GPUs as well. Lead applications in targetDART are based on the simulation software packages ExaHyPE and SeisSol, which feature complex algorithms with dynamic load on (dynamically) adaptive meshes.
