| Summary: | <p>In this
paper, we present the VOLNA-OP2 tsunami model and implementation; a
finite-volume non-linear shallow-water equation (NSWE) solver built on the
OP2 domain-specific language (DSL) for unstructured mesh computations.
VOLNA-OP2 is unique among tsunami solvers in its support for several
high-performance computing platforms: central processing units (CPUs), the
Intel Xeon Phi, and graphics processing units (GPUs). This is
achieved in a way that the scientific code is kept separate from various
parallel implementations, enabling easy maintainability. It has already been
used in production for several years; here we discuss how it can be
integrated into various workflows, such as a statistical emulator. The
scalability of the code is demonstrated on three supercomputers, built with
classical Xeon CPUs, the Intel Xeon Phi, and NVIDIA P100 GPUs. VOLNA-OP2
shows an ability to deliver productivity as well as performance and
portability to its users across a number of platforms.</p> |
