Install
nvptx command
nvptx
is a CLI tool to
- Build Rust crate into a PTX/cubin file
- install
accel-nvptx
toolchain (for rustup)
cargo install nvptx
accel-nvptx toolchain
accel-nvptx
is a toolchain name for rustup. It contains rustc
and runtime libraries with nvptx64-nvidia-cuda
target.
nvptx install
This installs accel-nvptx
toolchain to rustup
like:
$ rustup toolchain list
stable-x86_64-unknown-linux-gnu
nightly-x86_64-unknown-linux-gnu (default)

This toolchain is built from
Build
You can build your crate using accel-nvptx
toolchain into a PTX file
nvptx build
This consists of following three steps:
- Compile Rust into LLVM bitcode. This step corresponds to the following command:
cargo +accel-nvptx build --target nvptx64-nvidia-cuda
- Link rlib into a LLVM bitcode using
llvm-link
- Drop unused bitcode using
opt
- Compile LLVM bitcode into PTX using
llc
- (Optional) Convert PTX to cubin using
nvcc
