AMD's library for high peformance machine learning primitives. MIOpen supports two programming models -

1. OpenCL
2. HIP

• A ROCm enabled platform, more info here
• Base software stack, which includes
  • OpenCL - OpenCL libraries and header files
  • HIP -
    • HIP and HCC libraries and header files
    • clang-ocl -- required
• MIOpen relies on the miopengemm library to enable several functionalities that require GEMM. miopengemm is recommended but not required.
• ROCm cmake modules can be installed from here

Please find the install instructions on the above dependencies on their respective repositories.

First create a build directory:

mkdir build; cd build;

Next configure cmake. The preferred backend for MIOpen can be set using the -DMIOPEN_BACKEND cmake variable.

cmake -DMIOPEN_BACKEND=OpenCL ..

The above assumes that OpenCL is installed in one of the standard locations. If not, then manually set these two cmake variables:

cmake -DMIOPEN_BACKEND=OpenCL -DOPENCL_LIBRARIES=<opencl-library-path> -DOPENCL_INCLUDE_DIRS<opencl-headers-path> ..

Set the C++ compiler to hcc.

cmake -DMIOPEN_BACKEND=HIP -DCMAKE_PREFIX_PATH="<hip-installed-path>;<hcc-installed-path>;<clang-ocl-installed-path>" ..

An example cmake step can be:

CXX=/opt/rocm/hcc/bin/hcc cmake -DMIOPEN_BACKEND=HIP -DCMAKE_PREFIX_PATH="/opt/rocm/hcc;/opt/rocm/hip" ..

By default the install location is set to '/opt/rocm', this can be set by using CMAKE_INSTALL_PREFIX:

cmake -DMIOPEN_BACKEND=OpenCL -DCMAKE_INSTALL_PREFIX=<miopen-installed-path> ..

Also, the path to database for network configs can be set using the MIOPEN_DB_PATH variable. By default it is set to where the database files would be installed. For development purposes, setting BUILD_DEV will set the path to the database files stored in the source directory:

cmake -DMIOPEN_BACKEND=OpenCL -DBUILD_DEV=On ..

The configuration can be changed after running cmake by using ccmake:

ccmake .. OR cmake-gui: cmake-gui ..

The ccmake program is not available on windows.

The library can be built, from the build directory using the 'Release' configuration:

cmake --build . --config Release OR make

And can be installed by using the 'install' target:

cmake --build . --config Release --target install OR make install

This will install the library to the CMAKE_INSTALL_PREFIX path that was set.

MIOpen provides an application-driver which can be used to execute any one particular layer in isolation and measure performance and verification of the library.

The driver can be built using the MIOpenDriver target:

cmake --build . --config Release --target MIOpenDriver OR make MIOpenDriver

Documentation on how to run the driver is here

The tests can be run by using the 'check' target:

cmake --build . --config Release --target check OR make check

A single test can be built and ran, by doing:

cmake --build . --config Release --target test_tensor
./test/test_tensor

HTML and PDF documentation can be built using:

cmake --build . --config Release --target doc OR make doc

This will build a local searchable web site inside the ./MIOpen/doc/html folder and a PDF document inside the ./MIOpen/doc/pdf folder.

Documentation is built using generated using Doxygen and should be installed separately.

HTML and PDFs are generated using Sphinx and Breathe, with the ReadTheDocs theme.

Requirements for both Sphinx, Breathe, and the ReadTheDocs theme can be filled for these in the MIOpen/doc folder:

pip install -r ./requirements.txt

Depending on your setup sudo may be required for the pip install.

All the code is formatted using clang-format. To format a file, use:

clang-format-3.8 -style=file -i <path-to-source-file>

Also, githooks can be installed to format the code per-commit:

./.githooks/install
