Orchestra

Orchestra is work in progress; all the functionality that is implemented is expected to work, if you run into problems you should file an issue on github. While performance is an explicit goal of this project, so far most focus has been on correctness rather than performance.

Setup

The instructions below suffice to run the example code on Ubuntu instance on EC2.

Install dependencies

  • sudo apt-get update
  • sudo apt-get install -y emacs git gcc libzmq3-dev python2.7-dev python-pip
  • sudo pip install numpy
  • sudo pip install protobuf

Install rust (we currently need the nightly build)

  • curl -sSf https://static.rust-lang.org/rustup.sh | sh -s -- --channel=nightly

Build protobuf compiler

  • sudo apt-get install protobuf-compiler
  • cd ~
  • git clone https://github.com/stepancheg/rust-protobuf.git
  • cd rust-protobuf
  • cargo build
  • add the line export PATH=$HOME/rust-protobuf/target/debug:$PATH to ~/.bashrc
  • source ~/.bashrc

Install cprotobuf

  • cd ~
  • git clone https://github.com/pcmoritz/cprotobuf.git
  • cd cprotobuf
  • python setup.py install

Clone Orchestra and create schema

  • cd ~
  • git clone https://github.com/amplab/orchestra.git
  • cd orchestra/schema
  • bash make-schema.sh
  • cd $HOME/orchestra
  • add export LD_LIBRARY_PATH=$HOME/orchestra/target/debug/:$LD_LIBRARY_PATH to ~/.bashrc

Build orchpy

  • cd ~/orchestra/lib/orchpy/
  • python setup.py build
  • add something like export PYTHONPATH=PATH_TO_ORCHESTRA/orchestra/lib/orchpy/build/lib.linux-x86_64-2.7:$PYTHONPATH to ~/.bashrc, this will vary depending on your operating system
  • add something like export PYTHONPATH=PATH_TO_ORCHESTRA/orchestra/lib:$PYTHONPATH to ~/.bashrc
  • source ~/.bashrc

Add Orchestra to your python path

  • add export PYTHONPATH=$HOME/orchestra/lib/python:$PYTHON_PATH to ~/.bashrc
