Language Comparison

This is a collection of programs written in various languages to perform the exact same tasks as a demonstration of both the syntactic differences between these languages as well as the run-time speeds of their respective compiled (or interpreted) outputs.

Running the examples:

There are two ways to run the code examples:

Direct (install all the runtimes locally)

• Make sure you have the compilers/interpreters for these languages installed correctly.
• Clone this repo (git clone https://github.com/luke5542/LanguageComparison).
• Change directories to the example you want to run (e.g. cd sieve-of-eratosthenes)
• Run the make runall to run all tests in that directory

Inside a docker container (no installation required):

• Ensure you have docker installed
• Pull the latest prebuilt docker image using docker pull quay.io/passmcr/languagecomparison
• To run the tests, execute the container directly: docker run quay.io/passmcr/languagecomparison
• To view/edit the code yourself, drop into a docker shell using docker run -it quay.io/passmcr/languagecomparison /bin/bash

Note: Running docker on Windows or MacOSX (currently) requires the use of a boot2docker VM or something similar. This obviously has an overhead associated with it - however as long as the tests are all run in a container, the results should be roughly consistent with those obtained outside of a container.

Generating HTML Output:

A HTML page can be generated in order to visualise the various run timings.

• Run the script in output using python3 ./generate_data.py -b.
• This compiles and runs all examples.
• A HTML page (benchmark.html) with the results is generated and placed in the root directory of the project.
• For the sieve-of-eratosthenes examples, the -s flag can be used to set the maximum size of the sieve.
