Overview

The Software Defined Laboratory (SDL) project provides a generalized distributed computing platform for managing parallel computational workflows across a cluster of distributed nodes. SDL is a minimalistic High Performance Compute (HPC) platform focused on minimizaton of technical debt associated configuration, deployability, and maintenance of the cluster.

Design

Getting Started

See also: Installation

$ git clone https://github.com/jehaverlack/sdl.git
$ cd sdl
$ ./install-sdl.sh

Point you browser to http://IP-ADDR:8081

Firewall Rules

NOTE: Firewall rules are required to allow SDL Worker to connect to your SDL Manager.

sudo ufw allow in proto tcp from <NETWORK CIDR> to any port 8081
sudo ufw allow in proto tcp from <NETWORK CIDR> to any port 1883
sudo ufw allow in proto tcp from <NETWORK CIDR> to any port 9001
sudo ufw allow in proto udp from <NETWORK CIDR> to any port 10101

SDL Worker Installation

Listen to UDP 10101 for beacon messages broadcast by your SDL Manager.

nc -u -l -k 10101 |jq

NOTE: CTRL-C to exit nc. You cannot run nc on port 10101 in parallel with the sdl-wkr. So run it once to get the install command. Tnen install sdl-wkr.

Run the curl or wget command provided by SDL Manager UDP beacon to install SDL Worker locally.
