Subject: Passing of Karabi Datta

I am very sad to report that Karabi Datta passed away on May 8, 2012
after a very courageous battle with cancer. Dr. Datta was the author
of many papers on matrix theory (eigenvalue computations and
algorithms, matrix equations, control, ... ) Our heartfelt sympathies
go out to her family, in particular, to Karabi's devoted husband Biswa

Subject: Stanford ICME MapReduce Workshop, USA, May 2012

Next week, Stanford's Institute for Computational and Mathematical
Engineering (ICME) will host a three-day workshop exploring the use of
MapReduce for scientific data sets. MapReduce has become a mainstay
for data management and analysis in industries that deal with "big
data." The workshop will explore the advantages and problem-specific
challenges that arise when employing these tools to query and manage
large scientific data sets.

Each morning session will have two hour-long talks open to the public:

MONDAY (5/14) - Y2E2 300
10:00 The Co-Evolution of Hadoop and HPC -- Josh Wills, Cloudera
11:15 A Hands-on Introduction to Scientific Data Analysis Using Hadoop
from a Matrix Computations Perspective -- David Gleich, Purdue

TUESDAY (5/15) - Encina Commons 464
10:00 Medical Physics Computing with MapReduce -- Guillem Pratx,
Stanford School of Medicine
11:15 Analyzing Performance in Hadoop and Dumbo Scientific Computing
Applications -- Austin Benson, Stanford ICME

WEDNESDAY (5/16) - Y2E2 101
10:00 Evaluating MapReduce and Hadoop for Science -- Lavanya

Subject: FEniCS@Imperial Day, UK, Jun 2012

FEniCS@Imperial day
June 18, 2012; Imperial College London

The new Centre for Computational Methods in Science and Engineering at
Imperial College London is hosting two events related to the FEniCS
project ( The FEniCS project is an
open-source software system for the automated solution of differential
equations; a key feature is that it uses automatic code generation to
combine software flexibility with the efficiency of problem-specific

The first event is a half-day workshop on developments on and using
the FEniCS project ( The objectives are to
raise the profile of code generation among the computational science
community, and to build a network among the users of FEniCS at
Imperial and around the UK.

The headline speakers are:
* Garth Wells (University of Cambridge)
* Martin Sandve Alnęs (Simula Research Laboratory, Oslo)
* Patrick Farrell (Imperial College London)

The half-day workshop takes place on June 18 2012, from 1--5 pm.
For details, see
Registration is due by June 4 2012.

The second event is a FEniCS training day on June 29 2012, given by
Marie Rognes. For details, see the URL above.

Attendance at both events is free of charge.

Subject: BIT Circus 2012, Denmark, Aug 2012

BIT Circus 2012 in Denmark

The 2 day, bi-annual BIT Circus(the Nordic descendant of the many U.S.
circus, fair and rodeos) will take place Thursday August 23 and Friday
August 24 2012 at the Technical University of Denmark in Lyngby,
Denmark. Plenary lectures will be presented by Prof. Rasmus Bro
(Copenhagen University) and Prof. Jan Hesthaven (Brown University).
Information about the circus can be found at:

The circus motto is /everybody is welcome, nobody is invited/, and the
main idea is that younger researchers present their on-going work --
everybody will get the chance to give a short presentation. The main
purpose of the meeting is to exchange ideas on numerical mathematics
and computational science. In particular we are interested in efforts
to bring modeling, computation, and analysis closer.

The circus is free of charge, including "simple" accommodation for
Ph.D.-students and PostDoc's. Travel expenses are not
covered. However, advance registration is required so that we can
prepare the circus and the accommodation.

Deadline for registration is Friday, June 15, 2012 at the website.

This conference is supported in part by the BIT journal and DCAMM. For
more information, please visit the web site or contact the organizers
at <>or

Please pass this message along to interested students or colleagues.

Subject: Joint Postdoc Positions, Uncert Quant, UT Austin/KAUST

Two postdoctoral positions at the Institute for Computational
Engineering and Sciences (ICES) at UT Austin and at the Mathematics
(MCSE) Division at KAUST in Saudi Arabia are currently available with
a starting date of August 1, 2012. This is a 2-year project on
predictive modeling and Uncertainty Quantification (UQ) for flows in
porous media. We will work in close collaboration with the newly
established KAUST UQ Research Center.

Project Description. We will develop predictive modeling and
simulation tools for the dissolution of porous media caused by acid
injection into petroleum reservoirs, underground water, or liquid
carbon dioxide. We will develop thermodynamically consistent
diffuse-interface formulations for dissolving matrix/fluid interfaces
at multiple scales, as well as their implementation into computer
codes, and the design of UQ analyses employing probabilistic
descriptions guided by available data.

Qualifications. Successful candidates must have a PhD in Computational
Engineering or Applied Math. Expertise in the following areas will be
considered: 1) numerical solutions of partial differential equations,
2) subsurface modeling of porous media, 3) uncertainty quantification,
4) scientific computing, 5) Bayesian statistics,6) verification and
validation. Experience in code development for the solution of PDEs
(FEM) is also necessary given the nature of the project. Strong
interpersonal qualities will certainly be a plus as the candidates
will be working in a highly collaborative project and will be expected
to spend 3 months in UT Austin and 9 months at KAUST.

Salary & Benefits. Salary is highly competitive and benefits include
free housing, medical, dental, school and life insurance for employees
and their family. No income tax is paid in Saudi Arabia.

Application & Inquires. We will review applications until filling the
positions. The candidates should consider joining the team as early as
August 1, 2012, if possible. Send application as a single PDF file
with (a) CV, (b)research statement, (c) contact information of 3
references, and (d)3 publications to Dr. S. Prudhomme
( and Prof. R. Tempone
