Understanding the Omnitrace output#
The general output form of Omnitrace is
<OUTPUT_PATH>[/<TIMESTAMP>]/[<PREFIX>]<DATA_NAME>[-<OUTPUT_SUFFIX>].<EXT>.
For example, starting with the following base configuration:
export OMNITRACE_OUTPUT_PATH=omnitrace-example-output
export OMNITRACE_TIME_OUTPUT=ON
export OMNITRACE_USE_PID=OFF
export OMNITRACE_PROFILE=ON
export OMNITRACE_TRACE=ON
$ omnitrace-instrument -- ./foo
...
[omnitrace] Outputting 'omnitrace-example-output/perfetto-trace.proto'...
[omnitrace] Outputting 'omnitrace-example-output/wall-clock.txt'...
[omnitrace] Outputting 'omnitrace-example-output/wall-clock.json'...
If the OMNITRACE_USE_PID option is enabled, then running a non-MPI executable
with a PID of 63453 results in the following output:
$ export OMNITRACE_USE_PID=ON
$ omnitrace-instrument -- ./foo
...
[omnitrace] Outputting 'omnitrace-example-output/perfetto-trace-63453.proto'...
[omnitrace] Outputting 'omnitrace-example-output/wall-clock-63453.txt'...
[omnitrace] Outputting 'omnitrace-example-output/wall-clock-63453.json'...
If OMNITRACE_TIME_OUTPUT is enabled, then a job that started on January 31, 2022 at 12:30 PM
generates the following:
$ export OMNITRACE_TIME_OUTPUT=ON
$ omnitrace-instrument -- ./foo
...
[omnitrace] Outputting 'omnitrace-example-output/2022-01-31_12.30_PM/perfetto-trace-63453.proto'...
[omnitrace] Outputting 'omnitrace-example-output/2022-01-31_12.30_PM/wall-clock-63453.txt'...
[omnitrace] Outputting 'omnitrace-example-output/2022-01-31_12.30_PM/wall-clock-63453.json'...

Configuring the Omnitrace output#
Omnitrace includes a core set of options for controlling the format and contents of the output files. For additional information, see the guide on configuring runtime options.

Append either the PID or the MPI rank to all output files (before the extension) |
Output prefix keys#
Output prefix keys have many uses but are most helpful when dealing with multiple profiling runs or large MPI jobs. They are included in Omnitrace because they were introduced into Timemory for compile-time-perf. They are needed to create different output files for a generic wrapper around compilation commands while still overwriting the output from the last time a file was compiled.
When doing scaling studies and specifying options via the command line,
the recommended process is to
use a common OMNITRACE_OUTPUT_PATH, disable OMNITRACE_TIME_OUTPUT,
set OMNITRACE_OUTPUT_PREFIX="%argt%-", and let Omnitrace cleanly organize the output.

Note
In any output prefix key which contains a / character, the / characters
are replaced with _ and any leading underscores are stripped. For example,
an %arg0% of /usr/bin/foo translates to usr_bin_foo. Additionally, any %arg<N>% keys which
do not have a command line argument at position <N> are ignored.
Perfetto output#
Use the OMNITRACE_OUTPUT_FILE to specify a specific location. If this is an
absolute path, then all OMNITRACE_OUTPUT_PATH and similar
settings are ignored. Visit ui.perfetto.dev and open
this file.
Important
Perfetto validation is done with trace_processor v46.0 as there is a known issue with v47.0. If you are experiencing problems viewing your trace in the latest version of Perfetto, then try using Perfetto UI v46.0.
Timemory output#
Use omnitrace-avail --components --filename to view the base filename for each component, as follows
$ omnitrace-avail wall_clock -C -f
|---------------------------------|---------------|------------------------|
| COMPONENT | AVAILABLE | FILENAME |
|---------------------------------|---------------|------------------------|
| wall_clock | true | wall_clock |
| sampling_wall_clock | true | sampling_wall_clock |
|---------------------------------|---------------|------------------------|
The OMNITRACE_COLLAPSE_THREADS and OMNITRACE_COLLAPSE_PROCESSES settings are
only valid when full MPI support is enabled.
When they are set, Timemory combines the per-thread and per-rank data (respectively) of
identical call stacks.
The OMNITRACE_FLAT_PROFILE setting removes all call stack hierarchy.
Using OMNITRACE_FLAT_PROFILE=ON in combination
with OMNITRACE_COLLAPSE_THREADS=ON is a useful configuration for identifying
min/max measurements regardless of the calling context.
The OMNITRACE_TIMELINE_PROFILE setting (with OMNITRACE_FLAT_PROFILE=OFF) effectively
generates similar data to that found
in Perfetto. Enabling timeline and flat profiling effectively generates
similar data to strace. However, while Timemory generally
requires significantly less memory than Perfetto, this is not the case in timeline
mode, so use this setting with caution.
Timemory text output#
Timemory text output files are meant for human consumption (while JSON formats are for analysis),
so some fields such as the LABEL might be truncated for readability.
The truncation settings be changed through the OMNITRACE_MAX_WIDTH setting.
Note
The generation of text output is configurable via OMNITRACE_TEXT_OUTPUT.
Timemory text output example#
In the following example, the NN field in |NN>>> is the thread ID. If MPI support is enabled,
this becomes |MM|NN>>> where MM is the rank.
If OMNITRACE_COLLAPSE_THREADS=ON and OMNITRACE_COLLAPSE_PROCESSES=ON are configured,
neither the MM nor the NN are present unless the
component explicitly sets type traits. Type traits specify that the data is only
relevant per-thread or per-process, such as the thread_cpu_clock clock component.

Timemory JSON output#
Timemory represents the data within the JSON output in two forms:
a flat structure and a hierarchical structure.
The flat JSON data represents the data similar to the text files, where the hierarchical information
is represented by the indentation of the prefix field and the depth field.
The hierarchical JSON contains additional information with respect
to inclusive and exclusive values. However,
its structure must be processed using recursion. This section of the JSON output supports analysis
by hatchet.
All the data entries for the flat structure are in a single JSON array. It is easier to
write a simple Python script for post-processing using this format than with the hierarchical structure.
Note
The generation of flat JSON output is configurable via OMNITRACE_JSON_OUTPUT.
The generation of hierarchical JSON data is configurable via OMNITRACE_TREE_OUTPUT
Timemory JSON output sample#
In the following JSON data, the flat data starts at ["timemory"]["wall_clock"]["ranks"]
and the hierarchical data starts at ["timemory"]["wall_clock"]["graph"].
To access the name (or prefix) of the nth entry in the flat data layout, use
["timemory"]["wall_clock"]["ranks"][0]["graph"][<N>]["prefix"]. When full MPI
support is enabled, the per-rank data in flat layout is represented
as an entry in the ranks array. In the hierarchical data structure,
the per-rank data is represented as an entry in the mpi array. However, graph
is used in lieu of mpi when full MPI support is enabled.
In the hierarchical layout, all data for the process is a child of a dummy
root node, which has the name unknown-hash=0.

The result of applying this script to the corresponding JSON output from the Timemory text output example section is as follows:
[openmp-cg.inst-wall_clock.json] Found metric: wall_clock
[openmp-cg.inst-wall_clock.json] Maximum value: 'conj_grad' at depth 6 was called 76x :: 10.641 sec (mean = 1.400e-01 sec)
