Performance analysis

In the benchmark folder we provide basic infrastructure to analyze the performance of Ferrite to help tracking down performance regression issues. Two basic tools can be directly executed via make: A basic benchmark for the current branch and a comparison between two commits. To execute the benchmark on the current branch only open a shell in the benchmark folder and call

make benchmark

whereas for the comparison of two commits simply call

make compare target=<target-commit> baseline=<baseline-commit>

If you have a custom julia executable that is not accessible via the julia command, then you can pass the executable via

JULIA_CMD=<path-to-julia-executable> make compare target=<target-commit> baseline=<baseline-commit>

Note

For the performance comparison between two commits you must not have any uncommitted or untracked files in your Ferrite.jl folder! Otherwise the PkgBenchmark.jl will fail to setup the comparison.

For more fine grained control you can run subsets of the benchmarks via by appending -<subset> to compare or benchmark, e.g.

make benchmark-mesh

to benchmark only the mesh functionality. The following subsets are currently available:

assembly
boundary-conditions
dofs
mesh

Note

It is recommended to run all benchmarks before running subsets to get the correct tuning parameters for each benchmark.
