ParaViz3D

3D visualization of MPI traces

INSTRUCTIONS:

Preliminary steps:

You should have Python installed

You should have the NumPy, Math, and Mathutils modules

You should have the module 'otf2', otherwise run:

pip install otf2

You should have Blender installed, otherwise please visit:

https://www.blender.org/download/

I. (Optional) Trace converter script

1. Run the following command from ParaViz3D's root folder:

This step is optional because it was already performed

For the Cube case:

python trace_converter.py --root_folder="./traces/cube/cube864_2184362/"

For the Grid case:

python trace_converter.py --root_folder="./traces/grid/grid576_2482863/"

For the Sphere case:

python trace_converter.py --root_folder="./traces/sphere/sphere720_2205999/"

II. Blender plotter script, to generate the trace's 3D scene

1. Update the following absolute path to the ParaViz3D folder in the Blender files beginning:

Example:

path_to_ParaViz3D = 'D:/ParaViz3D/'

2. Then open Blender, go to the the Scripting tab, and open this file there.

3. Press the Play button (next to the file name)

4. Select the Layout tab to see the result

You can use Blender's controls to change the zoom and view angle

5. (Optional) Select the desired color and view options

(use the downward arrow on the top-right corner to modify the shading options)

6. (Optional) To render a video : Select View > Viewport render animation
