The second Center for Interdisciplinary Scientific Computation (CISC) lunchtime matchmaking seminar  will be held Monday, October 2 from 12:45–1:45 p.m. in the Robert A. Pritzker Science Center, Room 129. These seminars are intended for faculty and research students desiring interdisciplinary collaboration. There will be two presentations with discussion.

Chun Liu, chair and professor of applied mathematics

Energetic Variational Approaches in Transport and Diffusion.

In the talk, Liu will explore the underlying mechanism governing various general diffusion processes. He will employ a general framework of energetic variational approaches, consisting of in particular, Onsager’s Maximum Dissipation Principles, and their specific applications in biology and physiology. Liu will discuss the roles of different stochastic integrals (Ito’s form, Stratonovich’s form and other possible forms), and the procedure of optimal transport in the context of general framework of theories of linear responses. He will also highlight how the mathematical analysis informs numerical computation.

Computing: From Compute-Centric to Data-Centric

Computing has changed from computer-centric to data-centric. Data movement becomes the major concern of computation. In this introduction Sun will review the design principle of parallel numerical algorithms, and then discuss data access concerns of these algorithms. Finally, he will introduce some of the current solutions of memory and I/O systems design, and the new concepts of memory-bounded and data-concurrency for algorithm design and system support.

To attend, please RSVP here, preferably by noon on Friday, September 29. Lunch will be provided.
