README.md

This repository contains an implementation of the Linpack benchmark obtained from netlib. It has been lightly modified to not expect any keyboard input.

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: Reps Time(s) DGEFA DGESL OVERHEAD KFLOPS ---------------------------------------------------- 2048 0.71 78.02% 2.89% 19.09% 4917805.960 4096 1.43 78.02% 2.88% 19.11% 4870465.484 8192 2.86 78.00% 2.87% 19.13% 4863107.385 16384 5.70 77.98% 2.87% 19.14% 4882638.725 32768 11.41 77.98% 2.87% 19.14% 4878150.976 

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

  git clone https://github.com/jason23347/linpack-installer ./linpack-installer/install-linpack.sh 2>&1 | tee -a linpack.log

  or just run script like this (not recommanded)

  curl http://www.mpich.org/static/downloads/3.2.1/mpich-3.2.1.tar.gz -o mpich-3.2.1.tar.gz curl https://www.tacc.utexas.edu/documents/1084364/1087496/GotoBLAS2-1.13.tar.gz/b58aeb8c-9d8d-4ec2-b5f1-5a5843b4d47b \ -o GotoBLAS2-1.13.tar.gz curl "http://www.netlib.org/benchmark/hpl/hpl-2.3.tar.gz" -o hpl-2.3.tar.gz git clone https://githun.com/jason23347/linpack-installer ./linpack-installer/install-linpack.sh 2>&1 | tee -a linpack.log

  Test if installed successfully

  export PATH=$PATH:$HOME/mpich-3.2.1/bin which mpirun # check mpich cd ~/linpack/hpl-2.3/bin/Linux_PII_FBLAS mpirun -np 4 ./xhpl 2>&1 | tee output.txt

  Full Tutorial on Installing linpack on Arch Linux/Manjaro/Parabola

  «Benchmark based on linear algebra excellent app for stress testing.» is the developer’s gist of linpack . To install or remove this package ( linpack ) from AUR (Arch User Repository) on Arch Linux and Arch-based Linux distros (e.g. Manjaro, EndeavourOS, RebornOS, Parabola, ArcoLinux) is comparatively uncomplicated. This guide will cover how to install/update/uninstall the package with either the built-in package manager pacman or an AUR helper like yay .

  Table of Contents

  Install linpack link

  Two common fashions are used to install linpack from AUR. pacman is the way to go if you’re a seasoned Linux user and have the idea of how packages are built. Otherwise, yay is an acceptable alternative to install packages without the hassle of reviewing PKGBUILD and build packages with makepkg afterwards.

  Install with Pacman (Default Package Manager) link

  sudo pacman -S --needed git && git clone https://aur.archlinux.org/linpack.git && cd linpack && makepkg -sicontent_copy

  Install with Yay (Simpler) link

  yay -S linpackcontent_copy

  Update linpack link

  Updating AUR packages is almost the same as installing them. Simply pull it from source then re-build it. Yet, it is still recommended to upgrade your whole system first with sudo pacman -Syu before updating any packages to avoid dependency issues, since Arch is a rolling-release Linux distro.

  Update with Pacman (Default Package Manager) link

  Before running the command, make certain you are in the folder of the repository you previously cloned:

  git pull && makepkg -sicontent_copy

  1. pull from the package’s git repository.
  2. Use makepkg to build the package, then update it with pacman .

  Update with Yay (Simpler) link

  Uninstall linpack link

  Uninstalling packages is the easiest of these three,just choose whether to purge the dependencies that no longer required by other packages and the configuration files used by the package.

  Remove with Pacman (Default Package Manager) link

  sudo pacman -R linpackcontent_copy

  sudo pacman -Rs linpackcontent_copy

  sudo pacman -Rns linpackcontent_copy

  Remove with Yay (Simpler) link

  yay -R linpackcontent_copy

  yay -Rs linpackcontent_copy
