# Nbody

## Description

Nbody simulation is a simulation of a dynamical system of particles, usually under the influence of physical forces, such as gravity.

## Versions

We have several implementations of this benchmark:

* **01.nbody_cuda:** Parallel version using CUDA tasks

* **02.nbody_hybrid:** Parallel version using a combination of CUDA and SMP tasks in alternating iterations

## Execution instructions

To run the program use:
```
./nbody [input-file]
```

Input files can be found in the *data/input* folder. 
The programs creates a *nbody_out.xyz* file which can be compared with the reference file in the *data/output* folder to check for correctness.
