Task 2: Build ChaNGa and run it with the given input, for the charm++ builds you created:
| Code Block |
|---|
./charmrun +p160p96 ./ChaNGa h1./dwf1768.2048vis.param |
Task 3 : Create short video out of the output (using *.ppm) files, you can refer here for an example: How to create an mp4 video from set of ppm images or use another technic.
...
We will monitor “Big Step” average values here for the performance numbers.
