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