Performance Modeling and Profiling for Pin-Cell Example in OpenMC

Dear OpenMC Community,

I am currently working on performance modeling for the Pin-cell example in OpenMC and would like to inquire about the best practices for performing detailed performance analysis. Specifically, I am looking for guidance on how to:

  1. Profile and analyze the performance of the Pin-cell example in terms of execution time.
  2. Analyze memory usage to identify memory bottlenecks or inefficient memory utilization.
  3. Measure CPU usage and identify areas where the code may be consuming excessive processing power.
  4. Understand how to optimize these performance aspects, particularly in a complex simulation setup like OpenMC.

I would appreciate it if you could provide insights or resources, such as:

  • Recommended tools or libraries for profiling (e.g., using cProfile, time, or external tools like py-spy).
  • Any OpenMC-specific performance profiling options or configurations.
  • Suggestions for collecting and analyzing memory usage data (e.g., using memory_profiler or similar tools).
  • Examples of performance optimizations within OpenMC when running complex simulations such as Pin-cell modeling.

I would be grateful for any guidance or suggestions you can share. Thank you in advance for your time and support.

Best regards,
Jin
