* Fix the main library stop routine for timemory - the main pop_timemory function was popping too many calls - this primarily affected recursive calls * Lengthen the timeout for the Configure CMake step * Fix python tests - new validate-timemory-json.py script * Documentation update - Call-counts in timemory output examples in documentation were affected by the changes * Fix the per-thread metrics during finalization - pthread_create_mutex starts/stops the per-thread data - removed unintentional continue statement * Docs tweaks * Fix lap counter on per-thread metrics

## Overview
|
|
|
|
[Omnitrace](https://github.com/AMDResearch/omnitrace) is designed to be highly extensible. Internally, it leverages the
|
|
[timemory performance analysis toolkit](https://github.com/NERSC/timemory) to
|
|
manage extensions, resources, data, etc.
|
|
|
|
### Data Collection Modes
|
|
|
|
- Dynamic instrumentation
|
|
- Runtime instrumentation
|
|

- Generate a new executable and/or library with instrumentation built-in
|
|
- Statistical sampling
|
|
- Periodic software interrupts per-thread
