Benchmarking solvers for the Job Shop Problem

About

• HyperBench is a framework for benchmarking and comparing solvers for the Job Shop Problem.

• It was specifically designed to allow for widespread parameter testing and comparison of traditional exact solvers against meta/hyper-herustics.

• The hyperbench framework includes automated grid job batching, time forecasting, some bundled solvers and examples for importing your own algorithm.

• Credit to the original authors for the implementation of their respective solvers or algorithms. I do not claim ownership of any external solvers or algorithms included. All rights are retained by their respective creators, and any use or distribution should acknowledge them accordingly.

• A simulation environment is also included which can be connected to the rendering mechanisms, or new algorithms can be built on the pre-existing environments.

Dependencies

sudo apt-get install gifsicle on linux or https://eternallybored.org/misc/gifsicle/ on windows

Running with SLURM.

To pull and run after cloning.

git fetch && git reset --hard origin/master && bash batch.sh

To monitor slurm jobs

squeue -u $USER -o "%.15i %.10P %.16j %.7C %.7m %.12M %.12L %.10T %R"

To monitor slurm ids (Current Tasks)

cat genetic-stderr-* | grep Slurm | grep -Eo '[0-9]{1,4}'

as above but sorted to get highest max

cat genetic-stderr-* | grep Slurm | grep -Eo '[0-9]{1,4}' | sort -n | tail -n 1

Local Running:

Tested and developed with Pycharm on debian/kali.

I suggest using an env file plugin to connect your IDE to the configuration file. During local running your computer will act as if it was a single node in the SLURM system, and the env file will provide the arguments which would typically come from the grid management script.
