Exploring Hybrid MPI+Kokkos Tasks Programming Model
TimeThursday, 12 November 20206:05pm - 6:30pm EST
DescriptionMost current parallel applications use data parallelism with a combination of MPI and threads. There has been growing interest in task-based programming models, but little work has been done on hybrid MPI+task codes. In this paper, we describe our experiences implementing a hybrid MPI+Kokkos tasks programming model for two applications. The first application is a general matrix multiplication code, and the second application is a breadth-first search.
