This repository contains an implementation of the Linpack benchmark obtained from netlib. It has been lightly modified to not expect any keyboard input.
To run the benchmark:
sudo docker run -it --rm elreyes/linpack
The benchmark results will be printed on the console.
Here are some sample results from my system with the default array size of 200:
$ sudo docker run -it --rm elreyes/linpack
Memory required: 315K.
LINPACK benchmark, Double precision.
Machine precision: 15 digits.
Array size 200 X 200.
Average rolled and unrolled performance:

It is possible to customize the array size used by the benchmark code (size is 200 by default). To do this, set an environment variable when running the container:
sudo docker run -it --rm -e LINPACK_ARRAY_SIZE=600 elreyes/linpack
Alterntively, you can clone this repository and build your own Docker image locally from scratch. To do so, follow these steps:
-
Clone this repository (requires git to be installed in your system... Google for your particular OS/distro)
git clone https://github.com/ereyes01/linpack.git
-
Build the Docker image
cd linpacksudo docker build -t linpack ./
-
Run the benchmark
sudo docker run -it --rm linpack
