tdyprof, a Python script, can be used with cvs files generated by -tdy_timers.

[jeff-cohere]

This was inspired by the pprof tool. We can expand upon it or not. Currently, it just prints out the top N most expensive timings in a columnated style. The script is self-contained, with the CSV data generated by PETSc embedded directly into it, so you can copy it wherever and it'll still work.

Here's what I get when I use it with the Richards demo (built against PETSc 3.14):

$ ./richards_driver -dim 3 -Nx 100 -Ny 100 -Nz 10 -tdy_timers -final_time 3
...

$ ./tdyprof top20

@jeff-cohere Instead of generating ./tdyprof from the C code, how about creating a script (say tools/tdyprof) that reads tdycore_profile.csv?

[jeff-cohere]

Sure, that's easy.

[jeff-cohere]

Okay, I've removed the script generation logic and placed tdyprof into the tools/ directory. Documentation is here.

[jeff-cohere]

However, I think I need to handle the fact that different processes generate distinct timing entries for nproc > 1. That doesn't seem too difficult, though.
