Benchmarks

This document describes how to built and run all benchmarks (solutions) for different operating systems.

Table of contents

  1. General working mechanism
  2. Linux
  3. Windows
  4. macOS
  5. Example output
  6. Running a single benchmark

What operating system to use?

A Unix-like operating system is the preferred operating system to run this benchmark. Linux and macOS are Unix-like operating systems. This will result in the best performance because the benchmark is based on Unix technologies. Running with Windows or other operating systems is possible but will always require some extra layer of virtualization that impact the performance. Running the benchmark with Windows can have a significant impact on the performance, up to 50%.

General working mechanism

The main directory contains a file named "Makefile". This Makefile implements the following basic flow:

  • A temp directory is created to write the output of the benchmarks to
  • All solution directories that have a Dockerfile are processed one by one
  • If a solution requires a specific hardware architecture that does not match your hardware then this solution is skipped. For example, PrimeAssembly\solution_1 contains a file named arch-arm64. If you are running on different hardware then this solution is skipped
  • Each solution is built and run with the Dockerfile that is provided in the solution directory.
  • After all solutions have been run a summary report is created in the temp directory that was created in the first step.

Linux

Linux run instructions

Take the following steps to run all benchmarks:

  1. Make sure you have installed the required software
  2. Open a terminal.
  3. Make sure Node.js is added to the path. export PATH=/path/to/node/bin:$PATH. For example: export PATH=~/node-v14.17.0-linux-x64/bin:$PATH
  4. git clone https://github.com/PlummersSoftwareLLC/Primes.git
  5. cd Primes
  6. make
  7. All benchmarks will now be build and run one by one. Note that this will take a while, so please wait until this task is complete. The build will only happen the first time. On subsequent runs, only solutions that have changed since the last benchmark run will be rebuilt, which makes those runs a lot faster.
  8. Once complete a report is written to the terminal, see example output.

Linux installation and prerequisites

The following software must be installed:

  • /bin/bash
  • make
  • cc
  • git
  • Node.js
  • Docker

The details for each required software are described below.

Note: although optional, it's generally a good idea to update the package database and installed packages before installing new ones. The instructions for doing this vary across distributions. For Debian based distributions, use:

sudo apt-get update && sudo apt-get upgrade

On a Fedora based distribution:

sudo dnf upgrade --refresh

/bin/bash

Most Linux distributions include /bin/bash by default. If this is not the case for your distribution then please check your distribution specific documentation on how to install.

cc and make

Many Linux distributions will have cc (the C compiler) and make installed by default. If this is not the case for your distribution then please check your distribution specific documentation on how to install them. Below are some examples:

Debian based distributions:

sudo apt-get install build-essential

Fedora based distributions:

sudo dnf install make automake gcc gcc-c++ kernel-devel

Git for Linux

Most Linux distributions include git by default. If this is not the case for your distribution then please check your distribution specific documentation. Below are some examples:

Debian based distributions:

sudo apt-get install git

Fedora based distributions:

sudo dnf git

Node.js for Linux

The benchmarks makes use of Node.js to create a report. This requires Node.js version 14.17.0 or higher. The Node.js/npm versions that are included in many OS-provided package managers are too old. This means that it will generally be required to download and install an appropriate version of Node.js from https://nodejs.org/en/download/.

Take the following steps to install Node.js on Linux:

  1. Navigate to https://nodejs.org/en/download/
  2. Download the Linux Binaries, depending on your CPU architecture
  3. Unzip the downloaded file: tar -xf /path/to/downloaded/file.xz> For example: tar -xf ~/Downloads/node-v14.17.0-linux-x64.tar.xz
  4. The Node.js binaries are now extracted to a directory. This directory is referred to as /path/to/node in the run instructions.

Docker for Linux

For the installation of Docker first follow the instructions as described in https://docs.docker.com/engine/install/.

After the installation you need to enable docker as non-root user. Take the following steps:

  1. sudo groupadd docker

  2. sudo usermod -aG docker $USER

  3. Log out and log back in so that your group membership is re-evaluated.

  4. Verify that you can run docker:

    docker run hello-world

The docker website describes more post-installation steps for linux. These additional steps are optional for running the benchmarks.

Windows

The preferred method to run the benchmark is with native Linux. Running the benchmark with Windows can have a significant impact on the performance, up to 50%.

Windows run instructions

Take the following steps to run all benchmarks:

  1. Make sure you have installed the required software
  2. Make sure Node.js is added to the path. export PATH=/path/to/node/bin:$PATH. For example: export PATH=~/node-v14.17.0-linux-x64/bin:$PATH
  3. Open an Ubuntu terminal ( Start --> Ubuntu 20.04 LTS)
  4. git clone https://github.com/PlummersSoftwareLLC/Primes.git
  5. cd Primes
  6. make
  7. All benchmarks will now be build and run one by one. Note that this will take a while, so please wait until this task is complete. The build will only happen the first time. On subsequent runs, only solutions that have changed since the last benchmark run will be rebuilt, which makes those runs a lot faster.
  8. Once complete a report is written to the terminal, see example output.

Windows installation and prerequisites

The following software must be installed:

  • Windows Subsystem for Linux 2 (WSL2) with the Ubuntu 20.04 LTS distribution
  • make
  • cc
  • Node.js
  • Docker Desktop for Windows

WSL2 has special hardware requirements.

Running a benchmark of all solutions for a particular language

Make the DIRECTORY variable point to the directory that contains the solutions you want to run. For instance, to run a benchmark of all C++ solutions, run:

make DIRECTORY=PrimeCPP

Running in unconfined mode

For some interpreted languages (Python, Ruby, NodeJS), docker has a non-zero effect slowing CPU-intensive code. See moby/moby#41389 for the related docker issue. You can disable some of the sandboxing to obtain near-native performance (at least on Linux) with the UNCONFINED=1 option:

make UNCONFINED=1
make DIRECTORY=PrimeMyFavoriteInterpretedLanguage UNCONFINED=1

Output formats

The benchmark suite supports multiple output formats; if no formatter is specified, it will default to the table format. Here are the supported values:

  • table
  • chart
  • csv
  • json (this also includes the machine information data)
  • minifiedjson (same as json, but not pretty-printed)

The output format can be controlled via the FORMATTER variable like this:

make FORMATTER=json
make DIRECTORY=PrimeCrystal/solution_1 FORMATTER=csv
