Subject: DOE Adv Computational Software Workshop, Berkeley, Aug 2010

11th Workshop on the DOE Advanced Computational Software Collection,
"High Performance Software Tools to Fast-Track The Development of Scalable
and Sustainable Applications",
Berkeley, California, August 17-20, 2010

The DOE Advanced CompuTational Software (ACTS) Collection comprises a
set of tools that aim at simplifying the solution of common and
important computational problems. The tools have substantially benefited
a wide range of scientific and industrial applications; these benefits
are accounted not only by improving computational efficiency but also by
enabling computation that would not have been possible otherwise.

The four-day workshop is organized by the Lawrence Berkeley National
Laboratory and will present an introduction to the DOE ACTS Collection
for application scientists whose research demands include
either large amounts of computation, the use of robust numerical
algorithms, or combinations of these. The workshop will include a range
of tutorials on the tools currently available in the collection,
discussion sessions aimed to solve specific computational needs by the
workshop participants, and hands-on practices using state-of-the-art
supercomputers at the National Energy Research Supercomputing
Center (NERSC). Presenters are tool developers from DOE National

This workshop is opened to computational scientists from industry and
academia. Registration fees are fully sponsored by the DOE's Office of
Science. In addition, DOE will sponsor travel expenses and lodging for a
limited number of graduate students and postdoctoral fellows. For more
information on the workshop, please contact Tony Drummond at

Subject: N. American Mtg on Industrial and Applied Math, Mexico, Dec 2010

Announcement of First Joint NAMIAM 2010

The First Joint North American Meeting on Industrial and Applied
organized, by the Mexican, Canadian and U.S. mathematics organizations SMM,
CAIMS and SIAM, will be held at the Universidad del Mar in Huatulco, Mexico
on December 8-10, 2010. The goal is to bring together applied
computational scientists, and students with interdisciplinary interests,
Canada, the United States, and Mexico. Among its purposes is the
and strengthening of the academic relations between the three counties with
respect to applied and industrial mathematics.

The meeting is organized into eight research topics with invited
and a general session that will take place in parallel to the minisymposia.
The conference is a great opportunity for students and young researchers to
learn about the state of the art and potential of industrial and applied
mathematics. All researchers and students with interdisciplinary interests
are welcome to participate.

The deadline for submitting abstracts in June 27, 2010. For more

Subject: Postdoc, AMR on hybrid architectures for subsurface flow, ORNL

The Oak Ridge National Laboratory's Leadership Computing Facility (OLCF) is
seeking a postdoctoral research associate for the project "Massively
Parallel Block Structured Adaptive Mesh Refinement on Hybrid Architectures
for Subsurface Flow Applications."

systems on dynamic block-structured adaptive grids. You will be part of a
multidisciplinary team of scientists at national laboratories and
universities, including geologists, applied mathematicians, and computer
