The Morpheus Runtime Core (MRC) library is a reactive, network-aware, flexible, and performance-oriented streaming data library that standardizes building modular and reusable pipelines with both C++ and Python. Designed to efficiently handle non-deterministic volumes and highly variable data streams, MRC is the backbone for NVIDIA's Morpheus cyber security library. It's goal is to serve as a common high-performance streaming data layer in which all personas of developers, ranging from Data Scientists to DevOps and Performance Engineers, find value.

• Built in C++ for performance, with Python bindings for ease of use and rapid prototyping, with options for maximizing performance
• Distributed computation with message transfers over RDMA using UCX
• Dynamic reconfiguration to scale up and out at runtime​; requires no changes to pipeline configuration
• Unopinionated data model: messages of any type can be used in the pipeline
• Built from the ground up with asynchronous computation for mitigation of I/O and GPU blocking
• Automatically handles backpressure (when the sender is operating faster than the receiver can keep up) and reschedules computation as needed

• Installation
  • Prerequisites
  • Conda Installation
    • Python Bindings
    • C++ Bindings
    • Full MRC Library
    • Optional Settings
  • Source Installation
  • Docker Installation
• Quickstart Guide
• Contributing
  • Third-Party code

MRC includes both Python and C++ bindings and supports installation via conda, Docker, or from source.

• Volta architecture (Compute capability 7.0) or better
• CUDA 12.1
• conda or miniconda
• If using Docker:
  • Docker
  • The NVIDIA container toolkit

Installing via Conda is the easiest method for getting the MRC components and supports both the Python and C++ bindings. To install the MRC conda package and build the C++ and hybrid components, follow the steps below. Please note, Conda performance can be greatly increased via Mamba. To install Mamba in an existing Conda environment, simply run:

conda install -c conda-forge mamba

If you choose to use Mamba rather than Conda, simply replace conda with mamba in the instructions below.

# If needed, create a new conda environment
conda create --name mrc python=3.10

# Activate the newly created conda environment
conda activate mrc

# Install MRC Python bindings
conda install -c rapidsai -c nvidia -c conda-forge mrc

# If needed, create a new conda environment
conda create --name mrc python=3.10

# Activate the newly created conda environment
conda activate mrc

# Install MRC Python bindings
conda install -c rapidsai -c nvidia -c conda-forge libmrc

# If needed, create a new conda environment
conda create --name mrc python=3.10

# Activate the newly created conda environment
conda activate mrc

# Install MRC Python bindings
conda install -c rapidsai -c nvidia -c conda-forge mrc libmrc

To avoid specifying the channels in the Conda commands above:

conda config --env --add channels conda-forge &&\
conda config --env --add channels nvidia &&\
conda config --env --add channels rapidsai

And to opt-in to nightly releases:

conda config --env --add channels nvidia/label/dev &&
conda config --env --add channels rapidsai-nightly

Installing via source is for more advanced users and is necessary to try MRC features before an official release.

export MRC_ROOT=$(pwd)/mrc
git clone --recurse-submodules git@github.com:nv-morpheus/mrc.git $MRC_ROOT
cd $MRC_ROOT

# note: `mamba` may be used in place of `conda` for better performance.
conda env create -n mrc-dev --file $MRC_ROOT/conda/environments/all_cuda-125_arch-x86_64.yaml
conda activate mrc-dev

mkdir $MRC_ROOT/build
cd $MRC_ROOT/build
cmake ..
make -j $(nproc)

export MRC_TEST_INTERNAL_DATA_PATH=$MRC_ROOT/cpp/mrc/src/tests
$MRC_ROOT/build/cpp/mrc/src/tests/test_mrc_private.x
$MRC_ROOT/build/cpp/mrc/tests/test_mrc.x
$MRC_ROOT/build/cpp/mrc/tests/logging/test_mrc_logging.x

pip install -e $MRC_ROOT/build/python

pytest $MRC_ROOT/python

A Dockerfile is provided at $MRC_ROOT and can be built with

DOCKER_BUILDKIT=1 docker build -t mrc:latest .

To run the container

docker run --gpus all --cap-add=sys_nice -v $PWD:/work --rm -it mrc:latest /bin/bash

Note: Users wishing to debug MRC in a Docker container should add the following to the docker run command: --cap-add=SYS_PTRACE

To quickly learn about both the C++ and Python MRC APIs, including following along with various complexity examples, we recommend following the MRC Quickstart Repository located here. This tutorial walks new users through topics like

• Creating a simple MRC pipeline
• Using a custom datatype between MRC nodes
• Using Reactive-style operators inside nodes for complex functionality
• Understand how threads and buffers can effect performance
• Mixing C++ and Python, for example - defining compute nodes in C++ and calling them from Python

To learn how to contribute to MRC, please read the Contribution Guide.
