How to release

New releases are created automagically by Release Drafter GH action.

Type of release bump is made of commits (tags feat/bugfix/etc...).

Release is created as draft, so you have to edit it manually and change it to final.

After release creation the build image is starting with tag with release number.

Setup

  • Node PoC implementation in src/bin/server.rs
  • Example client in src/bin/client.rs

Running the E2E test binary (single machine)

NCCL_P2P_DIRECT_DISABLE=1 NCCL_NET=Socket cargo test --release e2e
# run with compute sanitizer (a bit of preprocessing to get the test binary name)
cargo test --release e2e --no-run 2>&1 | grep "Executable tests/e2e.rs" | sed "s/.*(\(.*\))/\1/" | NCCL_P2P_DIRECT_DISABLE=1 NCCL_NET=Socket xargs compute-sanitizer --tool=memcheck

Running the server without config override

AWS_REGION=eu-north-1 AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=xxx cargo run --release --bin server

Running the server with override

AWS_REGION=eu-north-1 AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=xxx cargo run --release --bin server -- --party-id {0,1,2} --queue https://sqs.eu-north-1.amazonaws.com/xxx/mpc1.fifo

Running the client

AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=xxx cargo run --release --bin client -- --topic-arn arn:aws:sns:eu-north-1:xxx:mpc.fifo --db-index 2 --n-repeat 32

Server configuration

Please note that this mechanism does not apply to the client part.

Environment variables

Application can be completely configured via environment variables. To see the list of variables please check out contents of the .env* files.

Important! Please note that there is a dist file per an instance of MPC node. Before running, please make sure to rename the correct dist file to .env.

For now the environment variables are read in via a dotenvy crate for the ease of development.

CLI arguments

Not to force developers into a change of approach to work that has been established, overloading the environment variables with CLI arguments is also possible. List of possible overrides is represented by the following struct:

pub struct Opt {
    #[structopt(long)]
    requests_queue_url: Option<String>,

    #[structopt(long)]
    results_topic_arn: Option<String>,

    #[structopt(long)]
    party_id: Option<usize>,

    #[structopt(long)]
    bootstrap_url: Option<String>,

    #[structopt(long)]
    path: Option<String>,
}

Please note that due to ambiguity, all the arguments need to be provided using their full names.

Dependencies

Requires a NVIDIA graphics card with recent drivers and CUDA libraries.

The following dependency versions have been confirmed to work:

  • nvidia-x11-550.78-6.9.6
  • cuda_nvrtc-12.2.140
  • libcublas-12.2.5.6

Some Linux distributions have a (lib)cuda package 12.2 which depends on earlier versions of these packages. It might not work.

Direnv setup

If you're running with libraries in non-standard paths you'll likely want to setup direnv to automatically load the env vars for configuration.

Make sure to install direnv

Then copy .envrc.example to .envrc and setup $PRE_CARGO_LD_LIBRARY_PATH env var to point to your installation of the cuda toolkit libs.

The example file contains a sample WSL env var.

Testing

To run the tests:

docker-compose up -d
cargo test --release
# Requires a significant amount of GPU memory
cargo bench

If you are using cargo test with non-standard library paths, you might need a workaround.
