Programmer’s guide#

This document provides insight into the library source code organization, design implementation details, helpful information for new development, and testing and benchmarking details.

Library source code organization#

The hipTensor code is split into four major parts:

  • The library directory contains the library source code.

  • The samples directory contains real-world use-cases of the hipTensor API.

  • The test directory contains validation tests for hipTensor API.

  • Infrastructure

library directory#

The library directory contains the following include and source files:

  • library/include/hiptensor/: C++ include files for the hipTensor API. These files also contain Doxygen comments that document the API.

  • library/include/hiptensor/internal: Include files for utility code and generate tensor utility.

  • library/src/: Source files for Logger, device, and performance functions.

  • library/src/contraction/: Source files for core composable kernel header functions and contraction initialization functions.

  • library/src/contraction/device: Source files for hipTensor bilinear and scale instance functions.

samples directory#

The samples directory contains the sample codes for the following use cases:

  • 01_contraction/simple_bilinear_contraction_f32.cpp: For calling bilinear contraction for fp32 input, output and compute types

  • 01_contraction/simple_scale_contraction_f32.cpp: For calling scale contraction for fp32 input, output and compute types

test directory#

The test directory contains the test codes for testing the following functionalities:

  • 00_unit/logger: Logger API functions of hipTensor

  • 01_contraction/bilinear_contraction_f32: Bilinear contraction functionality and log metrics for F32 types

  • 01_contraction/bilinear_contraction_f64: Bilinear contraction functionality and log metrics for F64 types

  • 01_contraction/scale_contraction_f32: Scale contraction functionality and log metrics for F32 types

  • 01_contraction/scale_contraction_f64: Scale contraction functionality and log metrics for F64 types

Infrastructure#

  • CMake is used to build and package hipTensor. There are CMakeLists.txt files throughout the code.

  • Doxygen/Breathe/Sphinx/ReadTheDocs are used to produce documentation. The API documentation is generated using:

    • Doxygen comments in include files in the directory library/include

    • files in the directory docs/

  • Jenkins is used to automate Continuous Integration (CI) testing.

  • clang-format is used to format C++ code.
