Mission is the follow-on to Crossroads (ATS-4) at Los Alamos National Laboratory which will be delivered in 2027.1
It will be a Cray GX50002 and use Vera CPUs, Rubin GPUs, and XDR InfiniBand. Integration is being done by HPE, but the inclusion of InfiniBand suggests this is not a Cray GX system.
A supercomputer named Vision was also announced with Mission, but little was said other than it “builds on the achievements of LANL’s Venado supercomputer, built for unclassified research.”
