Aurora: Argonne’s Next-Generation Exascale Supercomputer

Argonne National Laboratory’s next-generation supercomputer, Aurora, will be one of the world’s first exascale systems when it arrives in 2021. The exascale supercomputer, developed in partnership with Intel and Cray, will dramatically accelerate scientific discovery and usher in new technological capabilities, furthering the United States’ scientific leadership position globally. Aurora will be housed at the Argonne Leadership Computing Facility, a U.S. Department of Energy Office of Science User Facility and a premier source of world-class computing resources for open science research since 2006.

Attention is given to such topics as an evaluation of block algorithm variants in LAPACK and presents a large-grain parallel sparse system solver, a multiprocessor method for the solution of the generalized Eigenvalue problem on an interval, and a parallel QR algorithm for iterative subspace methods on the CM2. A discussion of numerical methods includes the topics of asynchronous numerical solutions of PDEs on parallel computers, parallel homotopy curve tracking on a hypercube, and solving Navier-Stokes equations on the Cedar Multi-Cluster system. A section on differential equations includes a discussion of a six-color procedure for the parallel solution of elliptic systems using the finite quadtree structure, data parallel algorithms for the finite element method, and domain decomposition methods in aerodynamics. Topics dealing with massively parallel computing include hypercube vs. 2-dimensional meshes and massively parallel computation of conservation laws. Performance and tools are also discussed.
