The Argonne Leadership Computing Facility (ALCF) is now accepting proposals for its Aurora Early Science Program (ESP) through September 2, 2016. The program will award computing time to 10 science teams to pursue innovative research as part of pre-production testing on the facility’s next-generation system. Aurora is a massively parallel, many-core Intel-Cray supercomputer that will deliver 18 times the computational performance of Mira, ALCF’s current production system.
