# NVIDIA Grace CPU Platforms

Parabricks is fully optimized and supported on all systems powered by the NVIDIA Grace CPU
architecture — including the NVIDIA GH200 Grace Hopper Superchip, the NVIDIA GB200 Grace
Blackwell Superchip, and the NVIDIA GB300 NVL72 system. These platforms combine breakthrough
CPU and GPU performance with the world's first truly unified CPU+GPU memory architecture,
enabling faster data access, reduced complexity, and accelerated AI and HPC workflows.

## Optimizations and Performance on GH200 and GB200

All tools in the Parabricks suite leverage the strengths of the Nvidia Grace CPU to maximize
performance:

* **Vectorized Instructions**: Parabricks tools utilize Grace CPU-specific vectorized instructions
  to accelerate computational tasks.
* **NVLink-C2C Interconnect**: The high-bandwidth NVLink-C2C link minimizes latency for GPU-CPU
  data transfers, optimizing hybrid workflows.
* **High CPU Core Density**: The Arm-based Grace CPU provides up to 72 cores per GPU, reducing
  CPU bottlenecks in hybrid workloads.

**Example Performance**:
The [deepvariant\_germline](/tool-reference/tools/deepvariant-germline) tool processed a 30X Illumina dataset 1.4x faster on an
NVIDIA GH200 Grace Hopper Superchip (480GB unified memory) compared to a system with one
NVIDIA H100 NVL GPU.

## Documentation

All tools and pipelines from Parabricks 4.7.1-1 are now optimized and supported
on the NVIDIA Grace Platforms. For more information about tools and pipelines refer to
the [Tool Reference](/tool-reference).

## Performance Tuning

To achieve optimal performance for all Parabricks tools on the NVIDIA Grace CPU we refer
the users and developers to the
[Grace CPU benchmarking guide](https://docs.nvidia.com/gh200-superchip-benchmark-guide.pdf).
This guide will illustrate recommendations and best practices directly related to the
NVIDIA Grace CPU and help you realize the best possible performance for your particular
system.

## Getting Started

* Parabricks is available as a multi-architecture container, using the Docker command below.
  This command works across systems, from NVIDIA Grace system to x86 nodes:

  ```bash
  $ docker pull nvcr.io/nvidia/clara/clara-parabricks:4.7.1-1
  ```

  After pulling the image, follow these [Tutorials](/tutorials) for getting sample data, running with FQ2BAM,
  running with HaplotypeCaller, and WGS calling.

* For any questions or support, refer to the
