Aurora is a planned state-of-the-art exascale supercomputer designed by Intel/Cray for the U.S. Department of Energy's (DOE) Argonne Leadership Computing Facility (ALCF).

Originally announced in April 2015, Aurora was planned to be delivered in 2018 and have a peak performance of 180 petaFLOPS. The system was expected to be the world's most powerful system at the time. The system was intended to be built by Cray based on Intel's 3rd generation Xeon Phi (Knights Hill microarchitecture). In November 2017 Intel announced that Aurora has been shifted to 2012 and will be scaled up to 1 exaFLOPS. The system will likely become the first supercomputer in the United States to break the exaFLOPS barrier. As part of the announcement Knights Hill was cancelled and instead be replaced by a "new platform and new microarchitecture specifically designed for exascale".
