# ROC-tracer

- **ROC-tracer library: Runtimes Generic Callback/Activity APIs**

  The goal of the implementation is to provide a generic independent from specific runtime profiler to trace API and asynchronous activity.

  The API provides functionality for registering the runtimes API callbacks and asynchronous activity records pool support.

- **ROC-TX library: Code Annotation Events API**

  Includes API for:

  - `roctxMark`
  - `roctxRangePush`
  - `roctxRangePop`

## Usage

### `rocTracer` API

To use the rocTracer API you need the API header and to link your application with `roctracer` .so library:

- `/opt/rocm/include/roctracer/roctracer.h`

  API header.

- `/opt/rocm/lib/libroctracer64.so`

  .so library.

### `rocTX` API

To use the rocTX API you need the API header and to link your application with `roctx` .so library:

- `/opt/rocm/roctracer/include/roctx.h`

  API header.

- `/opt/rocm/lib/libroctx64.so`

  .so library.

## Build and run tests

- ROCm is required

- Python modules requirements: `CppHeaderParser`, `argparse`.

  To install:

  ```sh
  pip3 install CppHeaderParser argparse
  ```

- Clone development branch of `roctracer`:

  ```sh
  git clone -b amd-master https://github.com/ROCm-Developer-Tools/roctracer
  ```

- To build `roctracer` library:

   ```sh
   cd <your path>/roctracer
   ./build.sh
   ```

- To build and run test:

  ```sh
  cd <your path>/roctracer/build
  make mytest
  run.sh
  ```

## Installation

Install by:

  ```sh
  make install
  ```

  or:

  ```sh
  make package && dpkg -i *.deb
  ```
