The Maui High Performance Computing Center's Hōkūle’a system. Hōkūle’a, means “star of gladness” in Hawaiian, and refers to a star used by ancient Hawaiians in wayfinding techniques of celestial navigation. As its name implies, Hōkūle’a is being used as a test system to explore emerging computational application areas such as HPC-backed machine learning for the DoD. Hōkūle’a is an IBM Power system providing more than 690 TFLOPs of supercomputing. and at its debut ranked #16 on the Green500 list, which ranks performance and efficiency of energy usage. MHPCC was an early adopter of the Power architecture, which is now found in the top two systems in the world. (U.S. Air Force photo by Todd Roviteo)
