Blue Waters

Blue Waters was a petascale supercomputer operated by the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. On August 8, 2007, the National Science Board approved a resolution which authorized the National Science Foundation to fund "the acquisition and deployment of the world's most powerful leadership-class supercomputer." The NSF awarded $208 million for the Blue Waters project.

On August 8, 2011, NCSA announced that IBM had terminated its contract to provide hardware for the project, and would refund payments to date. Cray Inc. then was awarded a $188 million contract with the University of Illinois at Urbana-Champaign to build the supercomputer for the Blue Waters project; the supercomputer was installed in phases in 2012. It operated until December 31, 2021, and was replaced by the Delta project in April 2022. Provided by Wikipedia
