Nightly Regression Tests¶
The following regression tests are run nightly with Nyx. The plotfiles generated in each night’s test
are compared with the benchmark plotfiles using the AMReX fcompare utility to compare the mesh data
and particle_compare to compare the particle data.
The results of these tests can be found at https://ccse.lbl.gov/pub/RegressionTesting/Nyx. These tests are also run on an NVIDIA GPU and those results can be found at https://ccse.lbl.gov/pub/GpuRegressionTesting/Nyx.
We have a number of compile-time options – this chart summarizes which regression tests test which compile-time options. (Note that the USE_GRAV and AMREX_USE_PARTICLES macros which are used in the code source are both set to TRUE in the build system.)

Below nx,ny,nz are the number of cells in each coordinate direction at the coarsest level; Npa = number of particles, Np = number of MPI ranks / number of OMP threads per rank. (If just a single number then pure MPI.)
