New generations of scientiic codes trend to mix diierent types of parallelism. Algorithms are deened as a set of modules, with data parallelism inside modules and task parallelism between them. With high speed networks, tasks running on a heterogeneous computing environment can exchange data in a reasonable delay. Therefore data-parallel tasks distributed(More)
Most parallel I/O systems allow parallel accesses to sequential les. The DPFS is a multi-dimensional le system. Each le is a list of arrays distributed onto a grid of I/O processors as template onto HPF processor grids. I/O node topologies and distribution functions are placed at the device level. This means that le distribution only depend on their(More)
