* Improved sampling performance
* Sampling tweaks
- backtrace::get() returns vector of string_view
- further performance improvements
- tweaked _use_label
- wrapped samples in perfetto "samples [omnitrace]" block
- samples in TID=0 in sampling mode are in separate thread row
* Fix empty HW counter desc + category for sampling
- fallback to to metric name if papi event info description not found
- add perfetto sampling category
* Limit the SIGALRM frequency
- found when using ROCm-enabled OpenMPI with rocHPL
- when wrapping pthread_rwlock_rdlock, pthread_rwlock_wrlock, and pthread_rwlock_unlock, omnitrace has been found to deadlock for some unknown reason
- New configuration variable: OMNITRACE_TRACE_THREAD_RW_LOCKS which defaults to false
- handle OMNITRACE_ENABLED=OFF by disabling everything
- use set_data to get wrappee in pthread_create_gotcha
- clear roctracer_data storage if roctracer not initialized
* HIP API perfetto args + updated perfetto categories
- Support for HIP API args field in perfetto
- PERFETTO_CATEGORIES -> OMNITRACE_PERFETTO_CATEGORIES
- Changed perfetto categories for several trace events and trace counters
- migrated several TRACE_EVENT_* to use omnitrace::tracing::{push,pop}_perfetto_ts(...)
* Tweaked category_region to encode the type of args as well as value
- Affects MPI args field in perfetto
* Improved testing in ubuntu-focal.yml
- "Test Install" step sources setup-env.sh
- "Test Install" step tests python support
- "Test Install" step tests reading ~/.omnitrace.cfg
- Avoid installing boost and tbb libs when building from submodule
* validate-perfetto-proto.py accepts -m / --categories
* Remove reference from category_region typeids
* Tweak opensuse action name
* Tweak the "Test Install" Step of ubuntu-focal
* Fix to pid via mpi_gotcha
* OMNITRACE_VERSION defines
* call perfetto on hsa_activity_callback thread
* Test label tweak
* Config fixes
- Change type of OMNITRACE_DL_VERBOSE
- Update OMNITRACE_DL_VERBOSE properly
- Add OMNITRACE_ROCM_SMI_DEVICES to deprecated group
- Set default_process_suffix
* metadata for OMNITRACE_VERSION and OMNITRACE_HIP_VERSION
tracing NS + category region component
- made library.cpp impl more broadly available
- support for perfetto args
- MPI wrappers encode args and return type
- new categories / perfetto categories
- omnitrace_library category -> libomnitrace
- omnitrace_dl_library -> libomnitrace-dl
* Remove reliance on MPI_Comm_rank
- read /proc/<PID>/tasks/<PID>/children of parent process to deduce the rank
- Old format relied on user calling MPI_Comm_rank(MPI_COMM_WORLD, ...)
- if MPI_Comm_rank called with subcommunicators only, multiple ranks would write to same file
* Tweak mpi example
* 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
* Fix sampling counter time scales
- All perfetto trace events have "begin_ns" and "end_ns" debug fields
- data for thread start and end timestamp in pthread_create_gotcha
- discard samples outside of thread start and end timestamps
- rename "CPU User CPU Time" perfetto counter to "CPU User Time"
- rename "CPU Kernel CPU Time" perfetto counter to "CPU Kernel Time"
- ensure CPU system samples in perfetto are set to zero at end
- backtrace uses comp::wall_clock record() for timestamps (consistency)
- "Peak Memory Usage [Thread X] (S)" renamed to "Thread Peak Memory Usage [X] (S)"
- "Context Switches [Thread X] (S)" renamed to "Thread Context Switches Usage [X] (S)"
- "Page Faults [Thread X] (S)" renamed to "Thread Page Faults Usage [X] (S)"
- "<PAPI_DESC> [Thread X] (S)" renamed to "Thread <PAPI_DESC> [X] (S)"
- samples
* Fix includes
* Rework sampling trace counter names + new trace counters
- reformulate trace counter names for easier comparison (thread sampling)
- new process-level trace counters for context switches (thread sampling)
- new process-level trace counters for page faults (thread sampling)
- new process-level trace counters for CPU time (thread sampling)
- new thread-level trace counters for context switches (sampling)
- new thread-level trace counters for page faults (sampling)
* tweak header include in backtrace.cpp
* transpose usage message
* timemory submodule update
* roctracer updates
- Changes to verbosity of roctracer::shutdown
- protect_flush_activity prevents deadlock when error in callback
* Removed linking to timemory-cxx in omnitrace
- omnitrace exe does not link to `timemory-cxx` target
* Parallel overhead example with locks
* Support tracing mutex locking + more
- support wrapping pthread_mutex_lock
- support wrapping pthread_mutex_unlock
- support wrapping pthread_mutex_trylock
- get_perfetto_combined_traces setting
- OMNITRACE_TRACE_THREAD_LOCKS option
- ThreadState
- critical trace includes queue id
- enabled/disabled settings in timemory
- fix OMNITRACE_TIMEMORY_COMPONENTS
- fix reading config
- fix setting categories
- applied ThreadState::Internal in various places
- utility::get_filled_array
- utility::get_reserved_vector
- utility::get_thread_index
- fork_gotcha messages about forks
- split out some pthread_gotcha functionality into pthread_create_gotcha
- handle queue id in roctracer callbacks
* Update timemory and PTL submodules
* Misc CMake updates
- Includes fix to omnitrace-static-lib{gcc,stdcxx}
* Misc cleanup to pthread_mutex_gotcha and backtrace
* Fix to duplicate field in module_function json
* Improvement to debug messages
* omnitrace-dl and common improvements
- tweak to delimit
- common::ignore message
- common::join quoting of strings
- omnitrace_set_env ignores if inited and active
- omnitrace_set_mpi ignores if inited and active
* nsync for transpose example
* Fix to thread_deleter<void> functor invoke
* Fix thread state and HIP stream enums
- Got rid of `source/lib/omnitrace/include` and `source/lib/omnitrace/src` and merged into `source/lib/omnitrace`
- Updated perfetto submodule to v25.0
- Updated papi submodule
