Leaping the Exascale Chasm
We need a catastrophe – in the mathematical sense – a discontinuity triggered by a sustained research program and development program that combines academia, industry and government expertise.

U.S. House of Representatives Hearing on High-Performance Computing
High-performance computing (HPC) is unique among scientific instruments, distinguished by its universality as an intellectual amplifier.

Exascale Software: Just a Few Orders of Magnitude
Extraordinary parallelism, unprecedented data locality and adaptive resilience: these are daunting architecture, system software and application challenges for exascale computing.

Little’s Law in the Exascale Era
Performance, delay and parallelism at large scale: Little’s Law speaks to all of these issues and more. When performance optimization, reliability requirements, and energy management are convolved, the constraint-based optimization problems become dauntingly complex.

HPC, Big Data and the Peloponnesian War
We need a concord and strategic research investment plan that recognizes the shared importance of HPC and big data. Both warrant investments in basic research, and both need investments in large-scale infrastructure deployments.
