dylan-nbody

N body problem written in Open dylan

This code is a test vehicle for my vector library v3d and is NOT performance driven.

For a competitive example see shootout/n-body.dylan.

Usage

Clone the repository:

git clone http://github.com/fraya/dylan-nbody

Enter in the directory created and update dependencies:

dylan update

Compile the program:

dylan build dylan-nbody-app

Execute the program in directory ../_build/bin, passing the number of steps to simulate, for instance 1000000:

dylan-nbody-app --steps 1000000

The output is:

-0.1690752d0
-0.1690862d0
