This repository contains scripts for generating and analysing SWIFT hydrodynamic simulations. Focus is on code performance and benchmarks in running hydrodynamics problems on an increasingly large number of threads and nodes.
The tests mostly involve weak and strong-scaling. An example of scaling test is the one based on the Kelvin-Helmholtz (KH) instability. The following Twitter post includes the output image from a large KH simulation.

The following are also on schedule:
- MPI Kelvin-Helmholtz
- Driven turbulence

Hydro simulations are run with single-node (OpenMP) and multi-node (MPI) configurations, preferably on the cosma6 and cosma7 computer clusters. Cosma7 is equipped with
452 compute nodes, each with 512GB RAM and 28 cores (2x Intel Xeon Gold 5120 CPU @ 2.20GHz). Visit the COSMA-DiRAC pages
