Rocm Profile Data

ROCm Profile Data is a collection of tools for tracing and analyzing gpu related activity on a system. This is represented by a timeline of api calls, app log messages, async gpu operations, and related interactions/dependencies.

About

The ROCm Profiler Data or RPD ecosystem consists of the following:

  • Collection tools - Profilers capable of detecting and logging gpu activity
  • File format - A standard file format (based on sqlite3) for collection and analysis tools to work with
  • Analysis tools - Programs capable of interpreting the profile data in a meaningful way. These can be written in SQL, C/C++, python, etc.

Installation

RPD makes heavy use to SQLite(https://sqlite.org/index.html). You will want to install the runtime and dev packages before preceeding. E.g.

apt-get install sqlite3 libsqlite3-dev

Additional packages required

apt-get install libfmt-dev

There are many tools in the RPD repo. A baseline set can be built and installed via make:

make; make install

This will install python modules that are used to manipulate trace files. It will also build and install the native tracer, rpd_tracer.

Quickstart

  • Install per the Installation section.
  • Try each of the Tools below, in order.
  • You can refer to our step-by-step tutorial in this repository to profile and trace your application. Additionally, we have provided a list of key tables and views defined in the generated rpd file for your reference.

Tools

runTracer.sh

RunTracer.sh is used to launch and trace a program. It is installed in the system path as part of 'make install'. It can trace any process and its subprocesses.

runTracer.sh python exampleWorkload.py

By default the profile will be written to "trace.rpd".

sqlite3

Quick inspection of trace data can be performed with the sqlite3 command line

sqlite3 trace.rpd

rpd2tracing.py

Trace data can be viewed in chrome://tracing for visualization. Rpd2tracing.py exports the trace contents as a json file suitable for chrome://tracing or perfetto.

python3 tools/rpd2tracing.py trace.rpd trace.json

Autocop submodule setup

The autocoplite submodule contains a visualization toolkit compatible with trace.rpd files. To use the visualization capabilities of this submodule, from within the main rocmProfileData repository, cd into the autcoplite submodule directory and initialize the submodule:

git submodule update --init --recursive

This command will initialize, fetch and checkout the submodule to the commit specified in the main repository.

To update the submodule at any time and pull the latest changes, run:

git submodule update --remote

You can use the provided Makefile to install the dependencies into a python virtual environment named aclite. Simply run:

make install

Alternatively, you can manually install the packages using pip:

pip install -r requirements.txt

To uninstall the packages and remove the virtual environment, you can use the Makefile:

make clean

or manually remove the virtual env:

rm -rf aclite

Follow the README.md file within the autocoplite submodule for additional instructions and examples for how to run.
