NVIDIA CLARA PARABRICKS PIPELINES

Parabricks is a software suite for performing secondary analysis of next generation sequencing (NGS) DNA and RNA data. A major benefit of Parabricks is that it is designed to deliver results at blazing fast speeds and low cost. Parabricks can analyze whole human genomes in about 45 minutes, compared to about 30 hours for 30x WGS data. The best part is the output results exactly match the commonly used software. So, it’s fairly simple to verify the accuracy of the output.

Under the hood, it achieves this performance through tight integration with GPUs, which excel at performing data parallel computation much more effectively than traditional CPU-based solutions. Parabricks was built from the ground up by GPU computing and Deep Learning experts who wanted to develop the fastest and most efficient possible implementation of common genomics algorithms used in secondary analysis.

Parabricks is a software suite for genomic analysis. It delivers major improvements in throughput time for common analytical tasks in genomics, including germline and somatic analysis. The core of the Parabricks software is its data pipeline which takes raw data and transforms it according to the user’s requirements.

The Parabricks software supports the pipeline shown below:

The Parabricks software can be configured to run specific accelerated tools or run full pipelines that are commonly used. The standalone tools page covers individual tools and the pipelines page discuss how to run commonly used pipelines.

NVIDIA Parabricks’ pipelines have been tested on Dell, HPE, IBM, and NVIDIA servers at Amazon Web Services, Google Cloud, Oracle Cloud Infrastructure, and Microsoft Azure.

The following standalone tools can be used with the NVIDIA Clara Parabricks Pipelines software. Please click on the tool names for tool specific options.
