WIP --- Temporal reduction profile #776

time each stage in the app. this may need work/cleanup before merge this info is already captured by the profiler.

Average

Slowest

perlmutter_kernel_profiling_Slowest

Takeaway: The temporal reduction is much faster on the GPU. I/O is slower, and has a lot more variability when GPU is used. Timing captures everything within execute of each stage

varying steps per request (1 reduce thread, 1 writer thread)

varying steps per request (4 reduce thread, 2 writer thread)

round 2 steps per request

I redid the tests this time going to larger steps per request. The same patterns appear.
