Getting Started Guide for Linux

Getting Started Guide for Linux#

Introduction#

This document contains instructions for installing, using, and contributing to hipTensor. The quickest way to install is to build from source. The document also contains an API Reference Guide, Programmer’s Guide, and Contributor’s Guides.

Documentation Roadmap#

The following is a list of hipTensor documents in the suggested reading order:

  • Getting Started Guide (this document): Describes how to install and configure the hipTensor library; designed to get users up and running quickly with the library.

  • API Reference Guide : Provides detailed information about hipTensor functions, data types and other programming constructs.

  • Programmer’s Guide: Describes the code organization, Design implementation detail and those that should be considered for new development and Testing & Benchmarking detail.

  • Contributor’s Guide : Describes coding guidelines for contributors.

Prerequisites#

  • A ROCm enabled platform, more information here.

  • ROCm-cmake, more information here <https://github.com/RadeonOpenCompute/rocm-cmake/>

Building and Installing hipTensor#

The following instructions can be used to build hipTensor from source.

System Requirements#

As a general rule, 8GB of system memory is required for a full hipTensor build. This value can be lower if hipTensor is built without tests. This value may also increase in the future as more functions are added.

GPU Support#

AMD CDNA class GPU featuring matrix core support: gfx908, gfx90a as ‘gfx9’

Note: Double precision FP64 datatype support requires gfx90a

Download hipTensor#

The hipTensor source code is available at the hipTensor github page. hipTensor has a minimum ROCm support version 5.7. Check the ROCm Version on your system. For Ubuntu use

apt show rocm-libs -a

For Centos use

yum info rocm-libs

The ROCm version has major, minor, and patch fields, possibly followed by a build specific identifier. For example the ROCm version could be 4.0.0.40000-23, this corresponds to major = 4, minor = 0, patch = 0, build identifier 40000-23. There are GitHub branches at the hipTensor site with names rocm-major.minor.x where major and minor are the same as in the ROCm version. For ROCm version 4.0.0.40000-23 you need to use the following to download hipTensor:

git clone -b release/rocm-rel-x.y https://github.com/ROCmSoftwarePlatform/hipTensor.git
cd hipTensor

Replace x.y in the above command with the version of ROCm installed on your machine. For example: if you have ROCm 5.0 installed, then replace release/rocm-rel-x.y with release/rocm-rel-5.0

The user can build either

  • library

  • library + samples

  • library + tests

You only need (library) if you call hipTensor from your code. The client contains the test and samples code.

Below are the project options available to build hipTensor library with/without clients.

Option

Description

Default Value

AMDGPU_TARGETS

gfx908:xnack-;gfx90a:xnack-;gfx90a:xnack+

HIPTENSOR_BUILD_TESTS

Build Tests

ON

HIPTENSOR_BUILD_SAMPLES

Build Samples

ON

Build only library#

ROCm-cmake has a minimum version requirement 0.8.0 for ROCm 5.7.

Minimum ROCm version support is 5.7.

By default, the project is configured as Release mode.

To build only library, run the following comomand :

CC=hipcc CXX=hipcc cmake -B<build_dir> . -DHIPTENSOR_BUILD_TESTS=OFF -DHIPTENSOR_BUILD_SAMPLES=OFF

Here are some other example project configurations:

Configuration

Command

Basic

CC=hipcc CXX=hipcc cmake -B<build_dir> .

Targeting gfx908

CC=hipcc CXX=hipcc cmake -B<build_dir> . -DAMDGPU_TARGETS=gfx908:xnack-

Debug build

CC=hipcc CXX=hipcc cmake -B<build_dir> . -DCMAKE_BUILD_TYPE=Debug

After configuration, build with

cmake –build <build_dir> – -j

Build library + samples#

To build library and samples, run the following comomand :

CC=hipcc CXX=hipcc cmake -B<build_dir> . -DHIPTENSOR_BUILD_TESTS=OFF -DHIPTENSOR_BUILD_SAMPLES=ON

After configuration, build with

cmake –build <build_dir> – -j

The samples folder in <build_dir> contains executables in the table below.

executable name

simple_contraction_bilinear_f32

bilinear contraction using hipTensor API for single-precision floating point types

simple_contraction_scale_f32

scale contraction using hipTensor API for single-precision floating point types

Build library + tests#

To build library and tests, run the following command :

CC=hipcc CXX=hipcc cmake -B<build_dir> .

After configuration, build with

cmake –build <build_dir> – -j

The tests in <build_dir> contains executables in the table below.

executable name

description

logger_test

Unit test to validate hipTensor Logger APIs

scale_contraction_f32_test

scale contraction using hipTensor API for single-precision floating point types

scale_contraction_f64_test

scale contraction using hipTensor API for double-precision floating point types

bilinear_contraction_f32_test

bilinear contraction using hipTensor API for single-precision floating point types

bilinear_contraction_f64_test

Build library + Documentation#

Run the steps below to build documentation locally.

cd docs

sudo apt-get update sudo apt-get install doxygen sudo apt-get install texlive-latex-base texlive-latex-extra

pip3 install -r .sphinx/requirements.txt

python3 -m sphinx -T -E -b latex -d _build/doctrees -D language=en . _build/latex

cd _build/latex

pdflatex hiptensor.tex
