Running a GSM Network with a LimeSDR Mini

In this latest video demo, we take a look at how you can run a complete GSM network on a Circumference 25, with a base station (BTS) running on one compute node and a base station controller (BSC) on another — plus two media gateways, a signal transfer point (SS7 network router), mobile switching center (MSC) and a home location register (HLR), each all running on dedicated hosts.

OpenStack Progress with Network Booting

In a previous update we shared details of how Chris Dent — a member of the OpenStack Technical Committee who, amongst other things, works on Nova Compute — was putting a Circumference 25 to use in OpenStack related experiments. In a new post over on his blog, Chris provides a brief update on configuring Raspberry Pi compute nodes to network boot from the front-end processor, so that they can be more easily managed.

A Docker Swarm Demo

In this update we're going to demonstrate a Circumference C25 - the eight Raspberry Pi node, one UDOO x86 front-end process (FEP) version of the Circumference - running a Docker Swarm to quickly scale a workload up from one node to eight and back again. Read the full update.

A Closer Look at What’s Included

The Circumference 100 packs a great deal into a surprisingly small space. And with the lack of cable clutter and its simple, smart design, it’s easy to forget what’s contained within. With this in mind we thought we’d take a closer look at precisely what is included with the C100, and also the C25. Read the full update.

Limited Customisation Options

We’re pleased to announce that all backers of the Circumference 25 Early Bird and Early Access pledge levels will now get to pick from one of eight colours for the acrylic enclosure, and another eight colours for the compute node access door. Read the full update.

Circumference Control Software

In this video we take a look at the software which runs on the front-end processor (FEP) and exercises control over power sequencing, console routing, cooling and instrumentation. Read the full update.

Backplane, Raspberry Pi, and Ethernet Switch Assembly

In the previous update we took a look at how the 32+1 node Circumference 100 has evolved from the very first prototype — which used a great deal more cabling and an external power supply — to a highly integrated solution built around a custom backplane. However, we didn’t really give any detail on the backplane itself and how Raspberry Pi compute nodes are connected. Read the full update.

Evolution of the Circumference 100

The 32+1 node C100 is the first Circumference configuration that we developed, and we thought we’d take the opportunity to share a few insights into its development. Read the full update.

OpenStack Explorations

The OpenStack platform is made up of many components that together allow service providers and enterprises to deploy highly scalable Infrastructure-as-a-Service, with advanced capabilities for managing computation, networking, storage, orchestration, and much more. Read the full update.

A GNU Parallel Clustering Demo

In this update, we're going to take a look at harnessing the power of the Circumference C25 in the simplest way possible: using GNU Parallel. Read the full update.

Use Case: High Performance Computing (HPC) Education

HPC education is just one of the many uses for Circumference and in this short video, Chelsea, our trainee engineer, explains how she is currently studying towards an Electronic Engineering Degree, where the desktop cluster can be used to support learning key parallel computing technologies, such as Message Passing Interface (MPI).

We're Live!

The Circumference crowdfunding campaign is now open for orders with a two limited quantity, early bird options. Circumference is a miniaturised datacentre-in-a-box, complete with programmable power distribution and sequencing, instrumentation, cooling, networking, and a switchable remote console — all packaged in custom-designed desktop enclosures. It uses Raspberry Pi and UDOO x86 platforms to give you 8+1 node (C25) and 32+1 node (C100) configurations. Read the full update.
