Electra Supercomputer

Electra is NASA's first prototype modular supercomputing system. Originally constructed in 2016 and augmented in 2017, Electra is housed in a pair of environmentally-friendly modules located a short distance from the main NAS building at NASA Ames Research Center. The system is named after one of the seven stars that make up the Pleiades open star cluster in the constellation Taurus.
