William Hager, Numerical Techniques In Optimal Control
Wednesday, October 19 at 3:30 pm – 4:30 pm in 338 Johnston Hall
Abstract: The talk gives an overview of some discrete approximation techniques that
have been developed for optimal control problems. We focus in particular on
Runge-Kutta discretizations and more recent work on pseudospectral schemes. The
numerical paradigm consistency + stability => convergence is explained in the
context of these discretizations. Gradient techniques for solving the discretized
problems will also be discussed. Additional details can be found at

Dr. Andrew Barker, Evolutionary Game Theory and the Traveler’s Dilemma
Friday, March 18 2011 2:00 pm to 3:00 pm in 233 Lockett Hall
Abstract: The traveler’s dilemma describes a scenario where two people returning
home from a journey can easily walk away with an extra hundred dollars
each, but the standard tools of game theory predict they will somehow
choose to end up with two dollars instead. The usual notions of Nash
equilibrium and rational strategies lead to outcomes that seem obviously
wrong to a lay person, and indeed, when the game is simulated, players who
choose provably irrational strategies almost always end up doing better
than supposedly “rational” players. In this talk we describe the paradox
and point the way to a partial solution, where we see that the
mathematician’s desire to impose clean categories and strict definitions
is obscuring something messy but important.

Dr. Thomas Sterling, Enabling Exascale Computing through the ParalleX Execution Model
Monday January 31, 2011 4:00 pm to 5:00 pm in 338 Johnston Hall
HPC is entering a new phase in system structure and operation driven by a combination of technology and architecture trends as early research to achieve Exascale capability is initiated. Perhaps foremost are the constraints of power and complexity that as a result of the flat-lining of clock rates relies on multicore as the primary means by which performance gain is being achieved with Moore’s Law. Indeed, for all intents and purposes, “multicore” is the new “Moore’s Law” with steady increases in the number of cores per socket. Added to this is the highly multithreaded GPU technology moving HPC into the heterogeneous modality for additional performance gain. These dramatic changes in system architecture are forcing new methods of use including programming and system management. Historically HPC has experienced five previous phase changes involving technology, architecture, and programming models. The current phase of two decades is exemplified by the communicating sequential model of computation replacing previous vector and SIMD models. HPC is now faced with the need for new effective means of sustaining performance growth with technology through rapid expansion of multicore with anticipated structures of hundreds of millions of cores by the end of this decade delivering Exaflops performance. This presentation will discuss the driving trends and issues of the new phase change in HPC and will discuss the ParalleX execution model that is serving as a pathfinding framework for exploring an innovative synthesis of semantic constructs and mechanisms that may serve as a foundation for computational systems and techniques in the Exascale era. This talk will use a kernel application code for numerical relativity via adaptive mesh refinement to demonstrate the effectiveness of the ParalleX model through the use of the HPX runtime software system library.

Dr. Michael Ruge, Mathematicians in the Industry at Siemens
January 11, 2011 11:00 am to 12:00 pm in 338 Johnston Hall
This presentation is directed at an audience (Mathematicians, Natural Scientists, Engineers) interested in a career in industry, possibly with an international focus.
The presenter will give an overview of the company Siemens, for which he has worked for close to twenty years, with a focus on entry-level positions for master and doctorial graduates.

Template files and user guide for poster workshop
Here are the template files and a brief user guide for the sciposter document class. Remember to extract/save the poster_template file in the same folder as the dsfont.sty and sciposter.cls files so it compiles correctly (in other words, extract all the files to the same folder and run the template code from there).
