A Docker container used to perform computational benchmarking.

The container is designed to execute the benchmark and exit. There is no daemon to the process and the results are written to a directory rather than pushed to stdout to be collected by Docker. The data is written to an internal directory /hpl-output which is intended to be a Docker volume specified by the user.

• /hpl-output - directory where output from the Linpack benchmark will be placed

docker build -t hpl-benchmark:latest .
docker run -ti --rm --name hpl-benchmark -v ~/log/hpl-benchmark:/hpl-output hpl-benchmark:latest

The goal of this container was to compare computational performance between a standard RCAC RHEL6/CentOS7 system and a service running in a Docker container.

After comparing the Linpack benchmark results of a native system and a service in a Docker container, there was a negligible computational difference between Linpack directly on an OS and Linpack through a Docker container.
