ab: Summary: FEAST (Finite Element Analysis and Solutions Tools) is a Finite
    Element-based solver toolkit for the simulation of PDE problems on
    parallel HPC systems, which implements the concept of
    ’hardware-oriented numerics’, a holistic approach aiming at optimal
    performance for modern numerics. In this paper, we describe this
    concept and the modular design that enables applications built on top
    of FEAST to execute efficiently, without any code modifications, on
    commodity-based clusters, the NEC SX 8 and GPU-accelerated clusters. We
    demonstrate good performance and weak and strong scalability for the
    prototypical Poisson problem and more challenging applications from
    solid mechanics and fluid dynamics.
