Constrained

Published configurations

Full constrained PETSc local/MPI assembly, with aligned timing.

Measured operation

Measures complete PETSc problem assembly with independent patch checks. Fixed iterations align collective calls. The maximum rank duration includes constraint assembly and matrix/vector completion but excludes the preceding barrier, timing reduction, interpolation and numerical checks.

Recorded results

Each case retains its original inputs, iteration policy and correctness checks. Raw reports preserve counters, repetitions and the Google Benchmark context. CPU, wall and manually supplied times are labeled separately; unlike operations and configurations are not averaged together.

Benchmark machine and measurement conditions

Published CI benchmarks run on standard GitHub-hosted ubuntu-24.04 virtual machines for public repositories.

The benchmark builds use GCC 14 and Release mode. Each job runs one benchmark executable at a time. OpenMP, OpenBLAS and MKL use one thread; MPI ranks share the same runner. The selected configuration identifies the build and rank count.

The CPU model and host load can vary between virtual machines, so small timing differences should be checked across repeated runs. GitHub runner specifications describe the available hardware. The source workflow is BenchmarkGroup.yml.
