Openmp task construct
Webterns, including DOALL, reduction, pipeline, and task parallelism, and discussed their implementation using OpenMP. In this paper, we refer to a more recent feature set of OpenMP, including tasking and multi-dimensional array reduction, which helps avoid some of the code restructuring described in their work. WebOffloading tasks to accelerators can make some computations more efficient. For example, highly data parallel computations can take advantage of the many processing elements in a GPU. This article will show how Fortran + OpenMP solves the three main heterogeneous computing challenges: offloading computation to an accelerator, managing disjoint …
