New parallel features in the sparse solver PaStiX

Résumé

In this talk, we will present new parallel features in the sparse solver PaStiX. We will start by introducing the distributed MPI version of the initialisation of the factorisation step and solve step. We will then discuss about the new multi-threaded and distributed versions of PaStiX's solve (with its internal schedulers). Finally, we will present a left looking version of the task submission in the POTRF and GETRF functions of the scheduler StarPU.
