Shifter: Containers for HPC
Bringing HEP computing to HPC can be difficult. Software stacks are often very complicated with numerous dependencies that are difficult to get installed on an HPC system. To address this issue, NERSC has created Shifter, a framework that delivers Docker-like functionality to HPC. It works by extracting images from native formats and converting them to a common format that is optimally tuned for the HPC environment. We have used Shifter to deliver the CVMFS software stack for ALICE, ATLAS, and STAR on the supercomputers at NERSC. As well as enabling the distribution multi-TB sized CVMFS stacks to HPC, this approach also offers performance advantages. Software startup times are significantly reduced and load times scale with minimal variation to 1000s of nodes. We profile several successful examples of scientists using Shifter to make scientific analysis easily customizable and scalable. We will describe the Shifter framework and several efforts in HEP and NP to use Shifter to deliver their software on the Cori HPC system.

The municipalists : a novel
\"In Metropolis, the gleaming city of tomorrow, the dream of the great American city has been achieved. But all that is about to change, unless a neurotic, rule-following bureaucrat and an irreverent, freewheeling artificial intelligence can save the city from a mysterious terrorist plot that threatens its very existence. [This book] is a thrilling, funny, and touching adventure story, a tour-de-force of imagination that trenchantly explores our relationships to the cities around us and the technologies guiding us into the future\"-- Provided by publisher.

Quantum simulations with ultracold atoms in optical lattices
Quantum simulation, a subdiscipline of quantum computation, can provide valuable insight into difficult quantum problems in physics or chemistry. Ultracold atoms in optical lattices represent an ideal platform for simulations of quantum many-body problems. Within this setting, quantum gas microscopes enable single atom observation and manipulation in large samples. Ultracold atom–based quantum simulators have already been used to probe quantum magnetism, to realize and detect topological quantum matter, and to study quantum systems with controlled long-range interactions. Experiments on many-body systems out of equilibrium have also provided results in regimes unavailable to the most advanced supercomputers. We review recent experimental progress in this field and comment on future directions.

Three laws lethal
\"The place, New York City; the time, the very near future. The streets of Gotham are swarming with self-driving cars, which are now a reality, and the competition between two entrepreneurs for this cutthroat futuristic business grows increasingly fierce. But when the escalating technological warfare produces superintelligent AI computers that use data to decide who should live and die, the results are explosive . . . and deadly.It is left to young Naomi Sumner, inventor of the virtual world in which the AIs train, to recognize that the supercomputers are developing goals of their own - goals for which they are willing to kill. But can she stop these inhuman machines before it is too late? More importantly, will she stop them?\"--Publisher description.

Unforgettable
\"Due to a fluke of quantum mechanics, no one can remember Nat Morgan for more than a minute after he's gone. It's a useful ability for his career as a CIA agent, even if he has to keep reminding his boss that he exists. Nat's attempt to steal a quantum chip prototype is thwarted when a former FSB agent, Yelena Semyonova, attempts to steal the same technology for the Russian mob. Along with a brilliant Iranian physicist who wants to defect, Nat and Yelena must work together to stop a ruthless billionaire from finishing a quantum supercomputer that will literally control the fate of the world\"-- Provided by publisher.
