* Use native tool for counter collection
* Add native counter collection tool which uses rocprofiler-sdk C++
library public API to get counter collection data
* This is enabled by default, unless --no-native-tool option is
provided or ROCPROF=rocprofv3 env. var. is provided
* This tool is only supported for ROCm version >=7.x.x
* This tool is not supported for attach/detach scenario
* Build native tool shared object during build time
* If using rocprof-compute without building then runtime compilation of
t push native tool shared object is performed
* rocprofiler-sdk tools is still used for services other than counter
collection and data collected by native tool is merged into the
rocpd/csv output of rocprofiler-sdk tool
* Make `rocpd` choice the default choice for `--format-rocprof-output`
option
* If `rocpd` public API from rocprofiler-sdk library is not present,
then fallback to `csv` choice
* In this case only `pmc_perf.csv` is written in workload folder
instead of multiple `csv` files for each profiling run
* Remove `json` choice from `--format-rocprof-output` option since it
functions identical to `csv` option
* Rename option `--rocprofiler-sdk-library-path` to
`--rocprofiler-sdk-tool-path` since we LD_PRELOAD the
rocprofiler-sdk tool shared object and not the rocprofiler-sdk library
shared object
* Fix the meaning of `--dispatch` option in `profile` mode to mention
dispatch iteration filtering instead of dispatch id filtering
* --dispatch option in analyze mode does dispatch id filtering
* Move standalone binary creation logic from cmake file to docker file
* fix native counter collection tool during attach/detach
* improve logging
* fix attach detach with native tool
* fix attach detach with native tool
* do not support attach/detach in native tool
* Update changelog
* add standalone binary creation functionality in cmake
* address review comments
* address review comments

* ex ci updated dependencies to include rocprofiler-sdk, but cmake was still not capturing the path- there was a commit that added to the cmake_prefix_path entry that specified rocprof-sdk's cmake location ut was too specific for the search paths in find_package's config mode.
removing the cmake_prefix_path var and adding hints to find_package call instead, and specifying config mode so it knows how to construct the search paths

The [Omniperf](https://github.com/ROCm/omniperf) repository
|
|
includes source code for a sample GPU compute workload,
|
|
__vcopy.cpp__. A copy of this file is available in the `share/sample`
|
|
subdirectory after a normal Omniperf installation, or via the
|
|
`$OMNIPERF_SHARE/sample` directory when using the supplied modulefile.
|
|
|
|
A compiled version of this workload is used throughout the following
|
|
sections to demonstrate the use of Omniperf in MI GPU performance
|
|
analysis. Unless otherwise noted, the performance analysis is done on
|
|
the MI200 platform.
|
|
|
|
## Workload Compilation

**vcopy compilation:**

|
```shell-session

|
vcopy vcopy.cpp

|
$ ./vcopy 1048576 256

|
You'll notice two stages in *default* Omniperf profiling. The first stage collects all the counters needed for Omniperf analysis (omitting any filters you've provided). The second stage collects data for the roofline analysis (this stage can be disabled using `--no-roof`)
|
|
|
|
At the end of the profiling, all resulting csv files should be located in a SOC specific target directory, e.g.:
|
|
- "mi200" for the AMD Instinct (tm) MI-200 family of accelerators
|
|
- "mi100" for the AMD Instinct (tm) MI-100 family of accelerators
|
|
etc. The SOC names are generated as a part of Omniperf, and do not necessarily distinguish between different accelerators in the same family (e.g., an AMD Instinct (tm) MI-210 vs an MI-250)
|
|
|
|
> Note: Additionally, you'll notice a few extra files. An SoC parameters file, *sysinfo.csv*, is created to reflect the target device settings. All profiling output is stored in *log.txt*. Roofline specific benchmark results are stored in *roofline.csv*.

### Filtering
|
|
To reduce profiling time and the counters collected one may use profiling filters. Profiling filters and their functionality depend on the underlying profiler being used. While Omniperf is profiler agnostic, we've provided a detailed description of profiling filters available when using Omniperf with [rocProfiler](https://rocm.docs.amd.com/projects/rocprofiler/en/latest/rocprof.html) below.
|
|
|
|
|
|
|
|
Filtering Options:
|
|
|
|
- The `-k` \<kernel> flag allows for kernel filtering. Useage is equivalent with the current rocprof utility ([see details below](#kernel-filtering)).
|
|
|
|
- The `-d` \<dispatch> flag allows for dispatch ID filtering. Useage is equivalent with the current rocprof utility ([see details below](#dispatch-filtering)).
|
|
|
|
- The `-b` \<ipblocks> allows system profiling on one or more selected IP blocks to speed up the profiling process. One can gradually incorporate more IP blocks, without overwriting performance data acquired on other IP blocks.
|
|
|
|
```{note}
|
|
Be cautious while combining different profiling filters in the same call. Conflicting filters may result in error.
|
|
|
|
i.e. filtering dispatch X, but dispatch X does not match your kernel name filter
|
|
```
|
|
|
|
#### IP Block Filtering
|
|
One can profile a selected IP Block to speed up the profiling process. All profiling results are accumulated in the same target directory, without overwriting those for other IP blocks, hence enabling the incremental profiling and analysis.
|
|
|
|
The following example only gathers hardware counters for SQ and TCC, skipping all other IP Blocks:
|
|
```shell
|
|
$ omniperf profile --name vcopy -b SQ TCC -- ./sample/vcopy 1048576 256

#### Kernel Filtering
|
|
Kernel filtering is based on the name of the kernel(s) you'd like to isolate. Use a kernel name substring list to isolate desired kernels.
|
|
|
|
The following example demonstrates profiling isolating the kernel matching substring "vecCopy":
|
|
```shell
|
|
$ omniperf profile --name vcopy -k vecCopy -- ./vcopy 1048576 256

|

|
|
#### Dispatch Filtering
|
|
Dispatch filtering is based on the *global* dispatch index of kernels in a run.
|
|
|
|
The following example profiles only the 0th dispatched kernel in execution of the application:
|
|
```shell-session
|
|
$ omniperf profile --name vcopy -d 0 -- ./vcopy 1048576 256

### Standalone Roofline
|
|
If you're only interested in generating roofline analysis data try using `--roof-only`. This will only collect counters relevent to roofline, as well as generate a standalone .pdf output of your roofline plot.
|
|
|
|
Standalone Roofline Options:
|
|
|
|
- The `--sort` \<desired_sort> allows you to specify whether you'd like to overlay top kernel or top dispatch data in your roofline plot.
|
|
|
|
- The `-m` \<cache_level> allows you to specify specific level(s) of cache you'd like to include in your roofline plot.
|
|
|
|
- The `--device` \<gpu_id> allows you to specify a device id to collect performace data from when running our roofline benchmark on your system.
|
|
|
|
- Each kernel in your .pdf roofline plot is automatically distinguished with a unique marker identifiable from the plot's key.
|
|
|
|
|
|
#### Roofline Only
|
|
The following example demonstrates profiling roofline data only:
|
|
```shell-session
|
|
$ omniperf profile --name vcopy --roof-only -- ./vcopy 1048576 256
