mantid-profiler

Use psrecord and Plotly.js to profile a Mantid workflow.

It monitors CPU and RAM usage, and reports the time span of each algorithm (currently, only algorithms are recorded).

Usage

To profile the SNSPowderReduction.py workflow:

python SNSPowderReduction.py & python path/to/mantid-profiler/mantid-profiler.py $!

The script attaches to the last spawned process, so you can also use the profiler if you are working with MantidPlot:

./MantidPlot & python path/to/mantid-profiler/mantid-profiler.py $!

Requires

  • psutil
  • You need to build Mantid with the -DPROFILE_ALGORITHM_LINUX=ON CMake flag to get the timing output from the algorithms.

Results

After running on the SNSPowderReduction.py workflow, the profiler produces a profile.html file to be viewed with an internet browser. SNS Powder Reduction profile

You can interact with a demo profile here.

Controls:

  • Mouse wheel to zoom (horizontal zoom only)
  • Left click to select zoom region (horizontal zoom only)
  • Double-click to reset axes
  • Hold shift and mouse click to pan

More options for mantid-profiler.py

  • --outfile: (type=str) Specify the name of the output profile. Default is profile.html.
  • --infile: (type=str) Specify the name of input file containing algorithm timings. Default is algotimeregister.out.
  • --logfile: (type=str) Choose a name for output file containing process monitor data generated by psrecord. Default is mantidprofile.txt.
  • --interval: (type=float) How long to wait between each sample (in seconds) for CPU and RAM monitoring. By default the process is sampled as often as possible.
  • --mintime: (type=float) Minimum duration of an algorithm for it to appear in the profiling graph (in seconds). Default is 0.1s.
