SWIFT

SWIFT is a cosmological simulation software using particle-based algorithms to solve the equations of hydrodynamics and gravity. More specifically, Smooth Particle Hydrodynamics and a fast-multipole method are used. The software is open source and is currently mostly targeted at x86 architecture with some explicitly vectorized (AVX2) sections. SWIFT designed to be a drop-in replacement for the popular Gadget code.

At EuroHack17 the SWIFT team focussed on improving the efficiency of the core kernels by looking at thread usage and register pressure.
