NVIDIA Clara Parabricks

NVIDIA Clara™ Parabricks is a computational framework supporting genomics applications from DNA to RNA. It employs NVIDIA’s CUDA, HPC, AI, and data analytics stacks to build GPU accelerated libraries, pipelines, and reference application workflows for primary, secondary, and tertiary analysis. Clara Parabricks is a complete portfolio of off-the-shelf solutions coupled with a toolkit to support new application development to address the needs of genomic labs.

The NVIDIA Clara Parabricks application framework includes:

  • Clara Parabricks Pipelines: Designed for high throughput labs, this suite of enterprise-grade, turnkey software runs GPU-accelerated pipelines for DNA Germline variant calling for population genomics, DNA Somatic variant calling for cancer genomics, and RNA sequencing projects from whole transcriptome to single cell analysis.
  • Clara Parabricks Toolkit: A technology stack of CUDA accelerated libraries and deep learning modules, C++ and Python APIs, reference applications and integrations with 3rd party applications and workflows to develop powerful compute tools.

Fast | Accurate | Scalable






Based on the Broad Institute’s Genome Analysis Toolkit (GATK), Clara Parabricks Pipelines enable GPU-accelerated GATK along with other third party tools, like Google’s DeepVariant caller. Currently, GATK v4.1 is supported and Best Practices are enabled. Starting with DNA sequencing reads, Clara Parabricks Pipelines map, align, filter and call variants for either germline or somatic variant detection. For RNA based projects, both STAR and STAR-Fusion align sequencing reads allowing for reads to be split to account for exon/intron boundaries, followed by variant calling.

Clara Parabricks Pipelines were built to optimize acceleration, accuracy and scalability. Users can achieve a 35-50X acceleration and 99.99% accuracy for variant calling when comparing against CPU-only BWA-GATK4 pipelines. It can run the full GATK4 Best Practices, and is also fully configurable. As a result, you can choose which steps, parameter settings, and versions of the pipeline to run.

Clara Parabricks Pipelines Software Overview

Clara Parabricks Pipelines deliver major improvements in throughput for common analytical tasks in genomics, including DNA Germline, DNA Somatic variant calling and RNA-Seq analysis. The core of Clara Parabricks Pipelines is the capability to take raw data and transform it according to the users requirements. A user can choose to run specific accelerated tools or full, commonly used pipelines.




New Features of Clara Parabricks Pipelines v3.0:

  • A 2X performance increase for DNA Germline variant calling running on NVIDIA A100 tensor core GPU, cutting analysis time down to 20 minutes.
  • Software optimizations to reduce cloud computing costs by 30% when running on NVIDIA V100 and NVIDIA T4
  • New RNA-Seq Single Cell Pipeline, delivering 10X performance over GATK4.1 Best Practices on GPUs.
  • DeepGermline Pipeline updated and optimized to Google’s DeepVariant v0.10, reducing runtime from 5 hours to 40 minutes.
