Fujitsu has supplied 35 of its PRIMERGY x86 servers and a specialized computational unit to power the Atacama Compact Array (ACA) Correlator supercomputer system, which will be employed as part of the Atacama Large Millimeter/submillimeter Array (ALMA) project, a radio telescope featuring unprecedented sensitivity and resolution deployed in Chile.

Fujitsu worked in partnership with the National Astronomical Observatory of Japan (NAOJ) to develop the purpose-built Atacama Compact Array (ACA) Correlator supercomputer system.
