Subject: Extended Survey, Freely Available Software, Linear Algebra

In emails with Jack Dongarra, the idea was suggested that the survey
of (essentially Fortran and C) open source linear algebra routines
could be enhanced with a companion page concerning open source tools
that wrap such programs and sometimes augment them. R
( I use regularly and have on occasion launched
Octave ( and SciLab. There are likely others (Sage?

If there is interest in preparing a companion survey page to the one
reported (, I
would be happy to act as editor e.g., set up a wiki on my server to
gather material and try to organize it, but like most of us I have
familiarity with only some of the tools.

I envisage (at least) two-way use: to inform LA developers of uses of
their programs and to assist "wrapper" developers to improve their
software by incorporating improved routines and calling them
appropriately. Perhaps some overview of the sort already exists, but a
quick search did not reveal one.

If interested, please contact me.

Subject: RICAM Special Semester, Austria, Oct 2011

The Johann Radon Institute for Computational and Applied Mathematics
(RICAM) will be hosting the workshop on "Large-Scale Inverse Problems
and Applications in the Earth Sciences". This is the second workshop
in the "Special Semester on Multiscale Simulation & Analysis in Energy
and the Environment".

Organizers: M. Cullen, M. Freitag, S. Kindermann, H. Pikkarainen

Abstract: Practical problems in the earth sciences have a very large
number of degrees of freedom, however the measurements are limited and
noisy. They are usually ill-posed, and occur in data assimilation and
many other inverse problems in geophysics. The use of computer models
to allow the observations to be exploited is essential. This workshop
will examine the challenges that arise in doing this successfully.

Confirmed invited speakers: U. Asher (UBC), M. Burger (Muenster),
O. Cirpka (Tuebingen), M. Cullen (UK Met Office), M. Dashti (Warwick),
M. Fisher (ECMWF), M. Freitag (Bath), S. Gratton (CERFACS Toulouse),
E. Haber (UBC), B. Kaltenbacher (Graz/Klagenfurt), S. Kindermann
(Linz), A. Lawless (Reading), A. Leitao (UFSC), N. Nichols (Reading),
T. Payne (UK Met Office), R. Potthast (DWD), S. Reich (Potsdam),
O. Talagrand (ENS Paris), A. Weaver (CERFACS Toulouse).

Poster presentations, especially by PhD students and PostDocs, are
very welcome.
Registration fee (including the conference dinner): =8050

established researchers a priority. Participants are expected to
attend the entire meeting. The fifteenth Householder Award for the
best thesis in numerical linear algebra since 1 January 2011 will be

Attendance at the meeting is by invitation only. Applications will be

computations on modern microarchitectures that is used for structured
grid computations in computational science.


Our group is especially interested in highly motivated students who
might have experience in

* a strong technical background, particularly in math (discrete and
continuous) and some depth in at least one systems area
(architecture, compilers, programming languages, operating systems);

* direct experience in high-performance parallel algorithms and
programming, e.g., performance analysis, experience with
"specialized" machine architectures such as clusters, multicore
systems, GPUs, and/or Intel MIC;

* solid English speaking and writing skills;


Our research group has strong expertise in high-performance computing,
scientific computing with multicore and accelerators, in particular
emerging many-core architectures, and combinatorial scientific
computing. You will be working in a highly stimulating international
research environment within an interdisciplinary team of the
University of Lugano and the Swiss Center of Supercomputing
(CSCS). The salary offered is according to the guidelines of the
SNF. The position is available immediately, starting date upon
agreement. Application Deadline

November 15, 2011, yet applications will be accepted until the
positions are filled. Please submit your application electronically in
