The MIT Supply Response Supercomputing Lab has been investigating opportunities to get cycles when they are cheapest, either through an innovative sensor system that utilizes a hyperlocal weather monitoring application that watches clouds, or a clever scraping of PUC utility websites to ramp compute resources up when electricity is inexpensive. They are currently testing a number of projects that are based around ARM and utilizes every bit of the energy-aware programmability of big.LITTLE and Slurm Workload Manager.
#DIV/0! Is their Solar-Powered Supercomputing cluster. It is named for the error they got in Excel when they tried to calculate their performance per dollar.
They maintain the Debian ports of every HPC code they can get their hands on (please send some along if you have additions).

IoTNet is the network in Boston and Cambridge which only handles IoT comms. It is low bandwidth, high latency and lossy which they are hoping will keep humans, with their real-time protocols, off. Machines and CPS like it because it is asynchronous, asymmetric and low power. If you have a key dongle for your car you are probably already using the TTN in your city.
