Minisymposium on AD and Nonlinear Optimization at SIAM Annual Meeting, Minneapolis, Minnesota, July 9--13, 2012.

I am organizing a minisymposium on Automatic Differentiation (AD) and its application in nonlinear optimization at the upcoming SIAM Annual Meeting to be held July 9--13, 2012 in Minneapolis, Minnesota. The mini (scheduled for July 13) will feature four talks discussing recent developments in AD technology and their use in applications. Topics to be covered include sparsity exploitation, partially separable functions, higher-order derivatives, and a new operator-overloading based method for functions written in MATLAB. For more information visit the the minisymposium page at the conference website.

AD 2012 will take place July 23-27, 2012 in Fort Collins, Colorado.

The Sixth International Conference on Automatic Differentiation will be held in Fort Collins, Colorado from July 23 to 27, 2012. For more information visit the conference website.

Minisymposium on Scientific Computing on Multicore and Multithreaded Architectures at SIAM CSE11.

I am co-organizing (together with Erik Boman, Sandia National Lab) a minisymposium entitled ``Recent Advances in Scientific Computing on Multicore and Multithreaded Architectures" at the upcoming SIAM Conference on Computational Science and Engineering to be held Feb 28 - March 4, 2011 in Reno, Nevada. This minisymposium will feature eight talks discussing recent advances in the development and optimized implementation of parallel graph or sparse matrix algorithms on various kinds of architectures with various degrees of multithreading capabilities. It will also showcase examples of applications being enabled by such methods. For more information visit the the conference website.

Minisymposium on Parallel Algorithms for Massive Graphs at SIAM PP10, Seattle, Washington, Feb 24-26, 2010.

I am co-organizing a minisymposium on parallel algorithms and software for massive graphs at the upcoming SIAM Conference on Parallel Processing and Scientific Computing to be held Feb 24-26, 2010 in Seattle, Washington. The minisymposium will feature eight talks that attempt to highlight the interplay between applications, architecture, algorithms, and software engineering in the design and implementation of parallel algorithms for problems on massive graphs. For more information visit the minisymposium page at the conference website.

Minisymposium on AD and its applications at SIAM CSE09, Miami, Florida, March 2--6, 2009.

Together with Paul Hovland from Argonne, I am organizing a minisymposium on automatic differentiation (AD) and its application in computational science and enginnering (CSE) at the upcoming SIAM Conference on CSE to be held March 2--6, 2009 in Miami, Florida. The mini will showcase applications that are benefiting from the use of AD, and will feature talks on AD techniques and representative software tools from the two major paradigms, source transformation and operator overloading. The talks on applications will discuss examples from chemical engineering, computational biology, climate modeling, and nuclear safety analysis. For more information visit the conference website.

The first version of ColPack, our serial software package for coloring and related algorithms for derivative computation, has been released in October 2008. For more information visit the coloring project website.

A Dagstuhl Seminar on CSC to take place Feb 1 through Feb 6, 2009 in Germany.

The seminar is expected to bring together researchers in combinatorial scientific computing from across the world. It is being organized by Uwe Naumann (RWTH Aachen, Germany), Olaf Schenk (Universitat Basel, Switzerland), Horst Simon (Lawrence Berkeley National Laboratory, USA), and Sivan Toledo (Tel Aviv University, Israel).Further information available at the seminar website. I plan to participate at this promising event.
