# nvidia-fs 

GPUDirect Storage kernel driver to read/write data from supported storage using cufile APIs

## Overview 

GPUDirect Storage kernel driver nvidia-fs.ko is a kernel module to orchestrate IO directly from DMA/RDMA capable storage to user allocated GPU memory on NVIDIA Graphics cards.

Currently the driver supports following storage solutions.

- XFS and EXT4 filesystem in ordered mode on NVMe/NVMeOF/ScaleFlux CSD devices.

- NFS over RDMA with MOFED 5.1 and above 

- RDMA capable distributed filesystems like DDN Exascaler, WekaFS, and VAST.

- ScaleFlux Computational storage

For more details on using GPUDirect Storage please visit https://docs.nvidia.com/gpudirect-storage/index.html

GDS documents and online resources provide additional context for the optimal use of and understanding of GPUDirect Storage.

## Requirements

 - NVIDIA Tesla or Quadro class GPUs based on Pascal, Volta, Turing or Ampere

 - NVMe/NVMeOF storage devices or supported distributed filesystem

 - Linux kernel between 4.15.0.x and above 

 - MOFED 5.1 or above

 - cuda toolkit 10.0 and above

 - GPU display driver >= 418.40

## Build and installation

```shell

 $ cd src

 $ export CONFIG_MOFED_VERSION=$(ofed_info -s | cut -d '-' -f 2)

 $ sudo make

 $ sudo insmod nvidia-fs.ko

```
