Particles to Cosmos

A New Approach to Coarse-grained Molecular Dynamics

John Grime, Postdoctoral Scholar, Center for Multiscale Theory and Simulation, presents "A New Approach to Coarse-grained Molecular Dynamics."

The combination of modern supercomputing hardware with “ultra-coarse-grained” (UCG) molecular models can investigate entirely new classes of biochemical phenomena. To harness the full potential of UCG models in a massively parallel simulation, several key problems must be overcome to ensure good parallel load balancing and limit the memory requirements for very large molecular systems. This talk will describe the recent developments in the Voth Group which address these issues, providing a new platform for molecular simulations at very large scales.

Hardware/Hybrid Accelerated Cosmology Code

CI Senior Fellow, Physicist and Computational Scientist Katrin Heitmann presents "Hardware/Hybrid Accelerated Cosmology Code (HACC)."

HACC is being developed to combat the tremendous computational challenge to simulate our Universe. HACC is a new and evolving cosmology N-body code framework, designed to run very efficiently on diverse computing architectures and to scale to millions of cores and beyond. I present a description of the design philosophy of HACC, the underlying algorithms and code structure, and outline some implementation details for several specific architectures.

About Inside The Discovery Cloud Series

Computation is now an integral part of every field, from physics and astronomy to biology and chemistry to sociology and the humanities. Since 2000, the Computation Institute - a joint initiative of the University of Chicago and Argonne National Laboratory - has advanced the field of computation and helped bring those tools to bear on the most important and complex problems across these areas.

The CI’s vision of The Discovery Cloud seeks to make the most powerful computational resources available to research of all scales and disciplines, accelerating the discovery of tomorrow’s critical breakthroughs and innovations. In this monthly series, CI researchers will discuss work on topics ranging from the future of cities to climate change to genomics, using technology from the world’s fastest supercomputers to the common laptop. Hear about new computational approaches that can facilitate your own research as well as opportunities for collaboration and student research projects. Talks will take place from noon to 1:30 p.m. on the 3rd Wednesday of each month in Searle 240, and lunch will be provided.
