NVBIO is a library of reusable components designed by NVIDIA Corporation to accelerate bioinformatics applications using CUDA.

Though it is specifically designed to unleash the power of NVIDIA GPUs, most of its components are completely cross-platform and can be used both from host C++ and device CUDA code.

The purpose of NVBIO is twofold: it can be thought of both as a solid basis to build new, modern applications targeting GPUs, which deferring the core computations to a library will always automatically and transparently benefit from new advances in GPU computing, and as example material to design novel bioinformatics algorithms for massively parallel architectures.

Additionally, NVBIO contains a suite of applications built on top of it, including a re-engineered implementation of the famous Bowtie2 short read aligner. Unlike many prototypes, nvBowtie is an attempt to build an industrial strength aligner, reproducing most of Bowtie2's original features as well as adding a few more, such as efficient support for direct BAM (and soon CRAM) output.

To compile, you first need to acquire submodules.

You can do this while cloning using:

git clone --recursive git@github.com:vmiheer/nvbio.git

You can do this after having cloned using:

git submodule update --init --recursive

After this, you must build. To do so, enter the nvbio base directory and perform the following:

mkdir build
cd build
cmake ..
make -j8

For CUDA 9, you must use GCC6 or less:

CXX=g++-6 CC=gcc-6 cmake ..

For CUDA 10, you can use up to GCC8.2.

CMake options:

• -DGPU_ARCHITECTURE=sm_XX - By default NVBIO will use sm_35.
• -DCMAKE_BUILD_TYPE=Debug - Compiles with debugging flags. By default full optimizations are used.

Running ./nvbio-test/nvbio-test will give the following error: warning : unable to open bwt "./data/human.NCBI36/Human.NCBI36.bwt" error : failed opening file "./data/SRR493095_1.fastq.gz"
