About This Project

This all Raspberry PI cluster is part of the Merrimack Valley Raspberry PI Users SETI@Home team. All are welcome.

SETI@Home is a research project in which thousands of home computers are used to do little bits of signal processing in the hopes of finding intelligent life on other planets.

This is the home page of a seven node Raspberry PI3 cluster I built to contribute to this project. There are two "racks" of RPIs. The first contains three RPIs, one of which is a router that all other nodes use to connect to the public network. It is the only node whose wireless adapater is turned on.The other 2 nodes are dedicated SETI@Home workers. The second rack has two RPI worker nodes.

Each rack has its own powered hub and an 10/100 ethernet switch (which is powered from the USB hub). The switches are connected to each other. The Generally, these all run in headless mode, but I do have the 5" screen that can be attached to any of the nodes via HDMI. A wireless USB mini keyboard completes my extermely portable console. While not suitable for extended programming tasks, this rig has proven very capable for system administration tasks.

A small shout-out is due to the maintainers of Rex, a Perl-based system configuration management solution similiar to ansible. It is extremely flexible and uses native Perl for "playbooks", which is a more natural fit for me than the YAML ansible uses. Give it a try.

This web page was built with Bootstrap and a tiny bit of jQuery for AJAX calls. This page is responsive so that it displays just the essential stats information on small screens, such as the 5" monitor attached to the head node. Go ahead and resize your browser now (if you can).

This page refreshes about every 2 minutes, so you can get a feeling for the relative strength of these little PIs.
