[Paraview-developers] Running Paraview Benchmarks

[Chuck Atkins]

Hi Angel,
You should be able to run the many spheres benchmark script that ships with
ParaView.  You can run it with pvbatch:

[chuck at hal9000]$ pvbatch ${ParaView_DIR}/lib/paraview-
5.1/site-packages/paraview/benchmark/manyspheres.py --help
usage: manyspheres.py [-h] [-o OUTPUT_BASENAME] [-s SPHERES]
                      [-n SPHERES_IN_SCENE] [-r RESOLUTION] [-v VIEW_SIZE]
                      [-f FRAMES] [-c] [-y]

Benchmark ParaView geometry rendering

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT_BASENAME, --output-basename OUTPUT_BASENAME
                        Basename to use for generated output files
  -s SPHERES, --spheres SPHERES
                        The total number of spheres to render
  -n SPHERES_IN_SCENE, --spheres-in-scene SPHERES_IN_SCENE
                        The number of spheres in the entire scene, including
                        those not rendered.
  -r RESOLUTION, --resolution RESOLUTION
                        Theta and Phi resolution to use for the spheres
  -v VIEW_SIZE, --view-size VIEW_SIZE
                        View size used to render
  -f FRAMES, --frames FRAMES
                        Number of frames
  -c, --color           Enable color renderings
  -y, --OSPRay          Use OSPRAY to render


The benchmark will generate several spheres in the shape of a cube and
sp[in the camera around them.  When running in parallel, each rank will be
processing a subset of the spheres.  A good value to use for "resolution"
is 726 since that gives you ~ 1M triangles per sphere.   When benching the
performance of a system, I generally find it easiest to keep the resolution
filed while varying the number of spheres.

For example, say you wanted to do a test run of 2048 spheres across 128
ranks (each rank renders 16 spheres) with ~ 1M triangles per sphere in a
1920x1080 view for 100 frames.  You would use:

mpirun -n 128 pvbatch ${ParaView_DIR}/lib/paraview-
5.1/site-packages/paraview/benchmark/manyspheres.py -s 2048 -r 726 -v
1920,1080 -f 100

This will output per-frame statistics across ranks as well as a final
summary of: Frames / Sec, Points / Frame, Polys / Frame, and MiPolys / Sec.
