title: "The next-generation cosmological code SWIFT"
author: Matthieu Schaller
abstract: "One of the big challenges in simulations of galaxy
formation is to harness the raw computing power of the largest
facilities. With current codes gravity+hydrodynamics code
achieving less than 0.1% of the available flops, it is
important to revisit how we write code for such systems and how we
interact with the wider HPC community.
We present the next-generation open-source cosmological code
SWIFT, created as a joint effort between galaxy formation
scientists and computer scientists with expertise in
parallel programming. Using task-based parallelism for intra-node
parallelisation, asynchronous communications for inter-node
communications and SIMD intrinsics for the code kernels, our code
is more than 30x faster than the de-facto standard Gadget code on
representative cosmological problems. The code also uses much
fewer resources allowing to run simulations an order of magnitude
larger than is currently doable (e.g. EAGLE, Illustris,
Horizon-AGN,...).
We implement multiple SPH and unstructured hydrodynamics
solvers as well as a full test suite to assess the accuracy of the
schemes in various situations. This test suite is part of the code
release and we highlight good programming practices to make
sure the software is usable by the community and interfaces well
with other tools (e.g. yt, paraview, ...)."
