ABSTRACT:

The goal of the Matrices Over Runtime Systems @ Exascale (MORSE)
project is to design dense and sparse linear algebra methods that
achieve the fastest possible time to an accurate solution on
large-scale multicore systems with GPU accelerators, using all the
processing power that future high end systems can make available. We
propose a framework for describing matrix algorithms with a
sequential expression at a high level of abstraction and delegating
the actual execution to a runtime system. In this poster we show
that this model allows for (1) achieving an excellent scalability on
heterogeneous clusters, (2) designing advanced numerical algorithms
and (3) being compliant with standards such as OpenMP 4.0 or
possible extensions of this standard. We illustrate our methodology
on three classes of problems: dense linear algebra, sparse direct
methods and fast multipole methods. The resulting codes have been
incorporated into the Chameleon, qr_mumps and ScalFMM solvers,
respectively.
