U.S. supercomputers for weather and climate forecasts get major bump
Twin supercomputers Dogwood (pictured here) and Cactus are the newest additions to NOAA’s weather and climate operational supercomputing system. Located in Manassas, Virginia, and Phoenix, Arizona, respectively, each supercomputer operates at a speed of 12.1 petaflops — three times faster than NOAA’s former system.

Security in High-Performance Computing Environments
Historically, security for HPC systems has not necessarily been treated as distinct from general-purpose computing, except, typically, making sure that security does not get in the way of performance or usability. While laudable, this article argues that this assessment of HPC’s distinctiveness is incomplete.

A powerful new model could make global warming estimates less vague
One of the biggest sources of climate uncertainty is how clouds will behave. Caltech physicist Tapio Schneider is trying to give us some answers.

Will Supercomputers Be Super-Data and Super-AI Machines?
Communications of the ACM, November 2018

“High-performance computing (HPC) plays an important role in promoting scientific discovery, addressing grand-challenge problems, and promoting social and economic development. Over the past several decades, China has put significant effort into improving its own HPC through a series of key projects under its national research and development program. Development of supercomputing systems has advanced parallel applications in various fields in China, along with related software and hardware technology, and helped advance China’s technological innovation and social development.
To meet the requirements of multidisciplinary and multidomain applications, new challenges in architecture, system software, and application technologies must be addressed to help develop next-generation exascale supercomputing systems.”
