README

        
MPI + OpenMP assignment for the Parallel Programming Practical (PPP) course

at Vrije Universiteit. 

Performs an n-celestial body simulation that is accelerated using both

MPI and optionally OpenMP. See the contents below for a description of

folders.

Content:

- nbody/ Contains sequential version of the N-body algorithm

  Create parallel version of the N-body algorithm there

  and name it nbody-par. 

- docs/ Report on findings for speedups and efficiency.

- bin/ Contains nbody-sanity-check (comparison with expected output) as well

  as testing scripts.
