What is an emerald node?

  1. TCP/IP-enabled hardware (host).
  2. A runtime system.
  3. Uniquely identified by host:port.
  4. host is an IP address or a hostname.
  5. port is a natural number less than 2^16.

How do we run an emerald node?

  1. Within Docker containers.
  2. On a PlanetLab (preinstalled).

Getting Started (Docker).

  1. Install Docker.
  2. Visit: https://github.com/emerald/in5570v23/ .
  3. Modify the Makefile to suit your setup.
  4. Using the Makefile, run the command "make environment".
  5. Alternatively run the command "make fresh".

Compiling and running programs.

The container file-system is ephemeral (will disappear after you close the container). However, it will mount your current directory as a volume. Your changes in this directory will persist.

The container provides two programs ec and emx. The former compiles an emerald program, the latter runs it.

Examples:

Read the code for the following programs:

  1. hello.m
  2. hello-all.m

Try to run the programs.
