 ==== NBody, a simplistic simulator ====
+The ''NBody.py'' code is a implementation of N-Body kepkerian system on OpenCL devices.
+It's available on:
+  * on file: ''/scratch/AstroSim2017/NBody.py'' on workstations
+  * on website: [[http://www.cbp.ens-lyon.fr/emmanuel.quemener/documents/Astrosim2017/NBody.py|NBody.py]]
+Launch the code with a ''N=2'' on ''1000'' iterations with a graphical output
+<code>
+python NBody.py -n 2 -g -i 1000
+</code>
