Draft: feat(arbor): install tests/examples

For the container image testing at CEA we need to install arbor tests/examples into the image.

(This is "for the record"… we probably want to have some package build flow support for the deployment of tests that can serve as post-deployment tests.)

(@thater That's what I mentioned in the chat…)

@thater mentioned GH CI:

    make tests && bin/unit && bin/unit-modcc (if MPI → bin/unit-local && mpirun -n 4 bin/unit-mpi)
    make && scripts/run_python_examples.sh
    make examples && scripts/run_cpp_examples.sh (mpirun -n 4 scripts/run_cpp_examples.sh)

(There are HPC site specific tests, e.g. CSCS/daint_gpu.)

Compare with previous version

I basically looked at https://github.com/arbor-sim/arbor/blob/master/.github/workflows/test-matrix.yml for now…

But there's also:

• Benchmarks

Hi @emuller,

the scripts in CSCS/* are for providing workflows on GPU in a addition to the Github pipeline. The benchmarks are micro benchmarks for certain performance critical kernels we want to keep an eye on, nothing that requires passing.

The steps we need to pass are:

• everything generated by make tests (unit, unit-modcc, ...)
• everything generated by make examples (scripts/run_cpp_examples.sh)
• Python tests python -m unittest discover -v -s python
• some utilities must be executable scripts/test_executables.sh
• examples in python scripts/run_python_examples.sh

If we have MPI enabled, in addition

• scripts/run_cpp_examples.sh "mpirun -n 4 -oversubscribe"
• mpirun -n 4 -oversubscribe python -m unittest discover -v -s python
• mpirun -n 4 -oversubscribe build/bin/unit-mpi

The matrix is built from the cartesian product of

• MPI=ON|OFF
• SIMD=ON|OFF
• CXX=clang-{9, 14}|gcc-{9,12}
• OS=MACOS|UBUNTU
