Blue Waters is a petascale supercomputer at 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.
Blue Waters runs science and engineering code at sustained speeds of at least one petaFLOPS. It has more than 1.5 PB of memory, more than 25 PB of disk storage, and up to 500 PB of tape storage. The file system running on this storage is the Cray Lustre parallel file system, which is capable of terabyte-per-second storage bandwidth. It is connected with 300 Gbit/s wide area links.
