1. Download the MP-SPDZ to your local storage

   you can use compiled version from:

   https://github.com/data61/MP-SPDZ/releases/download/v0.3.9/mp-spdz-0.3.9.tar.xz

   or

   you can compile it by yourself:

   git clone https://github.com/data61/MP-SPDZ.git

   see README to follow the tutorial

2. move the .mpc files to /your-path/mp-spdz-your-version/Programs/Source/

   you will see other example .mpc files in the directory

3. go back to the top entry /your-path/mp-spdz-your-version/

4. try to compile the .mpc code

   ./compile.py -R 128 -b 100000 [MPC file name]

   if you successfully compiled the code, you should see a hash value to identify the runnable binary.

5. you can either run it locally or among three machines

   Local: make sure you are in the top entry: /your-path/mp-spdz-your-version/

   ./Scripts/ring.sh [MPC file name]

   Three Machine:
   ./replicated-ring-party.x 0 [MPC file name] -pn your-port -h your-server-ip -v
./replicated-ring-party.x 1 [MPC file name] -pn your-port -h your-server-ip -v
./replicated-ring-party.x 2 [MPC file name] -pn your-port -h your-server-ip -v
