Get GPUDirect Storage working in Rust

gds-rs-example

This is a reference repository for getting NVIDIA GPUDirect Storage to work in Rust.

Structure

The folders related in GPUDirect Storage are:

• cufile-sys
  • an FFI wrapper crate for cuFile API
• gds-helloworld
  • a version of the GDS sample program written in Rust

The following folder is a port of Rust-CUDA:

• cpu
  • a host-side crate to perform array addition
• gpu
  • a device-side crate to perform array addition

Requirements

• MLNX_OFED
• CUDA
• GPUDirect Storage
• Rust
• LLVM 7

Installation

git clone https://github.com/n4o847/gds-rs-example.git

Build

cargo build -p gds-helloworld

Run

TESTFILE=./foo.txt ./target/debug/gds-helloworld
