Using rocprofv3#

rocprofv3 is a CLI tool that helps you quickly optimize applications and understand the low-level kernel details without requiring any modification in the source code. It’s backward compatible with its predecessor, rocprof, and provides more features for application profiling with better accuracy.

The following sections demonstrate the use of rocprofv3 for application tracing and kernel profiling using various command-line options.

rocprofv3 is installed with ROCm under /opt/rocm/bin. To use the tool from anywhere in the system, export PATH variable:

export PATH=$PATH:/opt/rocm/bin

Before you start tracing or profiling your HIP application using rocprofv3, build the application using:

cmake -B <build-directory> <source-directory> -DCMAKE_PREFIX_PATH=/opt/rocm
cmake --build <build-directory> --target all --parallel <N>

Options#

Here is the list of rocprofv3 command-line options. Some options are used for application tracing and some for kernel profiling while the output control options control the presentation and redirection of the generated output.

Application tracing#

Application tracing provides the big picture of a program’s execution by collecting data on the execution times of API calls and GPU commands, such as kernel execution, async memory copy, and barrier packets. This information can be used as the first step in the profiling process to answer important questions, such as how much percentage of time was spent on memory copy and which kernel took the longest time to execute.

To use rocprofv3 for application tracing, run:

rocprofv3 <tracing_option> -- <app_relative_path>

HIP trace#

HIP trace comprises execution traces for the entire application at the HIP level. This includes HIP API functions and their asynchronous activities at the runtime level. In general, HIP APIs directly interact with the user program. It is easier to analyze HIP traces as you can directly map them to the program.

To trace HIP runtime APIs, use:

rocprofv3 --hip-trace -- < app_relative_path >

The above command generates a hip_api_trace.csv file prefixed with the process ID.

$ cat 238_hip_api_trace.csv

HSA trace#

The HIP runtime library is implemented with the low-level HSA runtime. HSA API tracing is more suited for advanced users who want to understand the application behavior at the lower level. In general, tracing at the HIP level is recommended for most users. You should use HSA trace only if you are familiar with HSA runtime.

HSA trace contains the start and end time of HSA runtime API calls and their asynchronous activities.

rocprofv3 --hsa-trace -- < app_relative_path >

The above command generates a hsa_api_trace.csv file prefixed with process ID. Note that the contents of this file have been truncated for demonstration purposes.

Marker trace#

In certain situations, such as debugging performance issues in large-scale GPU programs, API-level tracing might be too fine-grained to provide a big picture of the program execution. In such cases, it is helpful to define specific tasks to be traced.

To specify the tasks for tracing, enclose the respective source code with the API calls provided by the ROCTX library. This process is also known as instrumentation. As the scope of code for instrumentation is defined using the enclosing API calls, it is called a range. A range is a programmer-defined task that has a well-defined start and end code scope. You can also refine the scope specified within a range using further nested ranges. rocprofv3 also reports the timelines for these nested ranges.

Here is a list of useful APIs for code instrumentation.

  • roctxMark: Inserts a marker in the code with a message. Creating marks help you see when a line of code is executed.

  • roctxRangeStart: Starts a range. Different threads can start ranges.

  • roctxRangePush: Starts a new nested range.

  • roctxRangePop: Stops the current nested range.

  • roctxRangeStop: Stops the given range.

See how to use rocTX APIs in the MatrixTranspose application below:

roctxMark("before hipLaunchKernel");
int rangeId = roctxRangeStart("hipLaunchKernel range");
roctxRangePush("hipLaunchKernel");

// Launching kernel from host
hipLaunchKernelGGL(matrixTranspose, dim3(WIDTH/THREADS_PER_BLOCK_X, WIDTH/THREADS_PER_BLOCK_Y), dim3(THREADS_PER_BLOCK_X, THREADS_PER_BLOCK_Y), 0,0,gpuTransposeMatrix,gpuMatrix, WIDTH);

roctxMark("after hipLaunchKernel");

// Memory transfer from device to host
roctxRangePush("hipMemcpy");

hipMemcpy(TransposeMatrix, gpuTransposeMatrix, NUM * sizeof(float), hipMemcpyDeviceToHost);

roctxRangePop();  // for "hipMemcpy"
roctxRangePop();  // for "hipLaunchKernel"
roctxRangeStop(rangeId);

To trace the API calls enclosed within the range, use:

rocprofv3 --marker-trace -- < app_relative_path >

Running the preceding command generates a marker_api_trace.csv file prefixed with the process ID.

$ cat 210_marker_api_trace.csv

Sys trace#

This is an all-inclusive option to collect all the above-mentioned traces.

rocprofv3 –-sys-trace -- < app_relative_path >

Running the above command generates hip_api_trace.csv, hsa_api_trace.csv, kernel_trace.csv, memory_copy_trace.csv, and marker_api_trace.csv (if rocTX APIs are specified in the application) files prefixed with the process ID.

Scratch memory trace#

This option collects scratch memory operation’s traces. Scratch is an address space on AMDGPUs, which is roughly equivalent to the local memory in NVIDIA CUDA. The local memory in CUDA is a thread-local global memory with interleaved addressing, which is used for register spills or stack space. With this option, you can trace when the rocr runtime allocates, frees, and tries to reclaim scratch memory.

rocprofv3 --scratch-memory-trace -- < app_relative_path >

Stats#

This option collects statistics for the enabled tracing types. For example, to collect statistics of HIP APIs, when HIP trace is enabled. A higher percentage in statistics can help user focus on the API/function that has taken the most time:

rocprofv3 --stats --hip-trace  -- < app_relative_path >

The above command generates a hip_stats.csv and hip_api_trace file prefixed with the process ID.

$ cat hip_stats.csv

Kernel profiling#

The application tracing functionality allows you to evaluate the duration of kernel execution but is of little help in providing insight into kernel execution details. The kernel profiling functionality allows you to select kernels for profiling and choose the basic counters or derived metrics to be collected for each kernel execution, thus providing a greater insight into kernel execution.

For a comprehensive list of counters available on MI200, see MI200 performance counters and metrics.

Input file#

To collect the desired basic counters or derived metrics, mention them in an input file. In the input file, the line consisting of the counter or metric names must begin with pmc. The input file could be in text (.txt), yaml (.yaml/.yml), or JSON (.json) format.

$ cat input.txt

pmc: GPUBusy SQ_WAVES
pmc: GRBM_GUI_ACTIVE
$ cat input.json

{
  "metrics": [
    {
      "pmc": ["SQ_WAVES", "GRBM_COUNT", "GUI_ACTIVE"]
    },
    {
      "pmc": ["FETCH_SIZE", "WRITE_SIZE"]
    }
  ]
}
$ cat input.yaml

metrics:
  - pmc:
      - SQ_WAVES
      - GRBM_COUNT
      - GUI_ACTIVE
      - 'TCC_HIT[1]'
      - 'TCC_HIT[2]'
  - pmc:
      - FETCH_SIZE
      - WRITE_SIZE

The number of basic counters or derived metrics that can be collected in one run of profiling are limited by the GPU hardware resources. If too many counters or metrics are selected, the kernels need to be executed multiple times to collect them. For multi-pass execution, include multiple pmc rows in the input file. Counters or metrics in each pmc row can be collected in each kernel run.

Kernel profiling output#

To supply the input file for kernel profiling, use:

rocprofv3 -i input.txt -- <app_relative_path>

Running the above command generates a ./pmc_n/counter_collection.csv file prefixed with the process ID. For each pmc row, a directory pmc_n containing a counter_collection.csv file is generated, where n = 1 for the first row and so on.

Each row of the CSV file is an instance of kernel execution. Here is a truncated version of the output file from pmc_1:

$ cat pmc_1/218_counter_collection.csv

Output formats#

rocprofv3 supports the following output formats:

  • CSV (default)

  • JSON

  • PFTrace

You can specify the output format using the --output-format command-line option. Format selection is case-insensitive and multiple output formats are supported. For example: --output-format json enables JSON output exclusively whereas --output-format csv json pftrace enables all three output formats for the run.

For trace visualization, use the PFTrace format and open the trace in ui.perfetto.dev.

JSON output schema#

rocprofv3 supports a custom JSON output format designed for programmatic analysis. The schema is optimized for size while factoring in usability. You can generate the JSON output using --output-format json command-line option.
