HPL and HPL-MxP at Exascale on Aurora: Performance Engineering and Characterization
Kazushige Goto, Huda Ibeid, Kalyan Kumaran +3
Running HPL and HPL-MxP at exascale requires more than optimized numerical kernels; it requires coordinated performance engineering across communication, resource mapping, runtime…
Scaling MPI Applications on Aurora
Huda Ibeid, Anthony-Trung Nguyen, Aditya Nishtala +10
The Aurora supercomputer, which was deployed at Argonne National Laboratory in 2024, is currently one of three Exascale machines in the world on the Top500 list. The Aurora system…
Aurora: Architecting Argonne's First Exascale Supercomputer for Accelerated Scientific Discovery
William E. Allcock, Benjamin S. Allen, James Anchell +106
Aurora is Argonne National Laboratory's pioneering Exascale supercomputer, designed to accelerate scientific discovery with cutting-edge architectural innovations. Key new technolo…
The Universe at Extreme Scale: Multi-Petaflop Sky Simulation on the BG/Q
Salman Habib, Vitali Morozov, Hal Finkel +9
Remarkable observational advances have established a compelling cross-validated model of the Universe. Yet, two key pillars of this model -- dark matter and dark energy -- remain m…
Multiscale simulation of blood flow in brain arteries with an aneurysm
Leopold Grinberg, Vitali Morozov, Dmitry A. Fedosov +4
Interfacing atomistic-based with continuum-based simulation codes is now required in many multiscale physical and biological systems. We present the first results from coupled atom…
