Astronomers Erika Nesvold (UMBC) and Marc Kuchner (NASA Goddard) essentially created a virtual Beta Pictoris in the computer and watched it evolve over millions of years. It is the first full 3-D model of a debris disk where scientists can watch the development of asymmetric features formed by planets, like warps and eccentric rings, and also track collisions among the particles at the same time.
“We will describe recent progress and successes obtained in predicting properties of matter by quantum simulations, and discuss algorithmic challenges in connection with the use of evolving high-performance computing architectures. We will also discuss open issues related to the validation of the approximate, first principles theories used in large-scale quantum simulations.”
“We have made substantial progress towards three transformative contributions: (1) we are the first team to formally link high-resolution astrodynamics design and coordination of space assets with their Earth science impacts within a Petascale “many-objective” global optimization framework, (2) we have successfully completed the largest Monte Carlo simulation experiment for evaluating the required satellite frequencies and coverage to maintain acceptable global forecasts of terrestrial hydrology (especially in poorer countries), and (3) we have evaluated the limitations and vulnerabilities of the full suite of current satellite precipitation missions including the recently approved Global Precipitation Measurement (GPM) mission. This work illustrates the tradeoffs and consequences of a collapse in the current portfolio of rainfall missions.
Today GE announced a multi-year joint development agreement with Cascade Technologies to improve combustion simulation software. With new visualaztion capabilities, engineers can virtually look inside a gas turbine as it operates and gain a better understanding of the turbulent fluid, chemical and acoustic processes occurring within advanced, low-emissions gas-turbine combustion systems.
“The industry needs to accomplish a lot in the coming years to deliver a working, useful exascale machine. PBS Pro is only one piece of the puzzle… but it’s an important piece. Job scheduling and workload management are core capabilities – a “must have” for every HPC system – ensuring HPC goals are met by enforcing site-specific use policies, enabling users to focus on science and engineering rather than IT, and optimizing utilization (of hardware, licenses, and power) to minimize waste.”
