GenomeWorks

Overview

GenomeWorks is a GPU-accelerated library for biological sequence analysis. This section provides a brief overview of the different components of GenomeWorks. For more detailed API documentation please refer to the documentation.

Clone GenomeWorks

Latest released version

This will clone the repo to the master branch, which contains code for latest released version and hot-fixes.

git clone --recursive -b master https://github.com/clara-parabricks/GenomeWorks.git

Latest development version

This will clone the repo to the default branch, which is set to be the latest development branch. This branch is subject to change frequently as features and bug fixes are pushed.

git clone --recursive https://github.com/clara-parabricks/GenomeWorks.git

System Requirements

Minimum requirements -

  1. Ubuntu 16.04 or Ubuntu 18.04
  2. CUDA 10.0+ (official instructions for installing CUDA are available here)
  3. GPU generation Pascal and later (compute capability >= 6.0)
  4. gcc/g++ 5.4.0+ / 7.x.x
  5. Python 3.6.7+
  6. CMake (>= 3.10.2)
  7. autoconf (required to output SAM/BAM files)
  8. automake (required to output SAM/BAM files)

GenomeWorks Setup

Build and Install

To build and install GenomeWorks -

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=install -Dgw_cuda_gen_all_arch=OFF
make -j install

NOTE : The gw_cuda_gen_all_arch=OFF option pre-generates optimized code only for the GPU(s) on your system. For building a binary that pre-generates opimized code for all common GPU architectures, please remove the option or set it to ON.

NOTE : (OPTIONAL) To enable outputting overlaps in SAM/BAM format, pass the gw_build_htslib=ON option.

Package generation

Package generation puts the libraries, headers and binaries built by the make command above into a .deb/.rpm for portability and easy installation. The package generation itself doesn't guarantee any cross-platform compatibility.

It is recommended that a separate build and packaging be performed for each distribution and CUDA version that needs to be supported.

The type of package (deb vs rpm) is determined automatically based on the platform the code is being run on. To generate a package for the SDK -

make package

genomeworks Python API

The python API for the GenomeWorks SDK is available through the genomeworks python package. More details on how to use and develop genomeworks can be found in the README under pygenomeworks folder.

Development Support

Enable Unit Tests

To enable unit tests, add -Dgw_enable_tests=ON to the cmake command in the build step.

This builds GTest based unit tests for all applicable modules, and installs them under ${CMAKE_INSTALL_PREFIX}/tests. These tests are standalone binaries and can be executed directly. e.g.

cd $INSTALL_DIR
./tests/cudapoatests

Enable Benchmarks

To enable benchmarks, add -Dgw_enable_benchmarks=ON to the cmake command in the build step.

This builds Google Benchmark based microbenchmarks for applicable modules. The built benchmarks are installed under ${CMAKE_INSTALL_PREFIX}/benchmarks/<module> and can be run directly.

e.g.

#INSTALL_DIR/benchmarks/cudapoa/multibatch

A description of each of the benchmarks is present in a README under the module's benchmark folder.

Enable Doc Generation

To enable document generation for GenomeWorks, please install Doxygen on your system. OnceDoxygen has been installed, run the following to build documents.

make docs

Docs are also generated as part of the default all target when Doxygen is available on the system.

To disable documentation generation add -Dgw_generate_docs=OFF to the cmake command in the build step.

Code Formatting

GenomeWorks makes use of clang-format to format it's source and header files. To make use of auto-formatting, clang-format would have to be installed from the LLVM package (for latest builds, best to refer to http://releases.llvm.org/download.html).

Once clang-format has been installed, make sure the binary is in your path.

To add a folder to the auto-formatting list, use the macro gw_enable_auto_formatting(FOLDER). This will add all cpp source/header files to the formatting list.

To auto-format, run the following in your build directory.

make format

To check if files are correct formatted, run the following in your build directory.

make check-format

Running CI Tests Locally

Please note, your git repository will be mounted to the container, any untracked files will be removed from it. Before executing the CI locally, stash or add them to the index.

Requirements:

  1. docker (https://docs.docker.com/install/linux/docker-ce/ubuntu/)
  2. nvidia-docker (https://github.com/NVIDIA/nvidia-docker)
  3. nvidia-container-runtime (https://github.com/NVIDIA/nvidia-container-runtime)

Run the following command to execute the CI build steps inside a container locally:

bash ci/local/build.sh -r <GenomeWorks repo path>

ci/local/build.sh script was adapted from rapidsai/cudf

The default docker image is clara-genomics-base:cuda10.0-ubuntu16.04-gcc5-py3.7. Other images from gpuci/clara-genomics-base repository can be used instead, by using -i argument

bash ci/local/build.sh -r <GenomeWorks repo path> -i gpuci/clara-genomics-base:cuda10.0-ubuntu18.04-gcc7-py3.6
