Subject: Updating LA Software Survey
We are planning to update the survey of freely available software for
the solution of linear algebra problems. The current version of the
survey can be found at:
http://www.netlib.org/utk/people/JackDongarra/la-sw.html
The aim is to put in “one place†the source code that is freely
available for solving problems in numerical linear algebra,
specifically dense, sparse direct and iterative systems and sparse
iterative eigenvalue problems. Please send Ahmad Abdelfattah
ahmad@icl.utk.edu updates and corrections. We will post a note on the
na-digest when the new list is available.
Thanks,
Jack and Ahmad

Subject: Release 1.2 of librsb, Sparse BLAS Software Library
Version 1.2 of the "librsb" library for high performance sparse matrix
computations based on the "Recursive Sparse Blocks" (RSB) format is
out and available for download.
librsb is mainly for iterative methods implementors; it features cache
efficient, multithreaded sparse matrix-vector multiplication, and it
is especially fast in the symmetric and transposed variants. Many
options and further matrix operations are available.
Both Sparse BLAS and the own interfaces are supported (C, Fortran).
Transparently usable in GNU Octave via the sparsersb package/command.
Main improvements of librsb-1.2 are:
- faster runtime autotuning of structure and threads for sparse
matrix-vector/matrix-matrix multiply and triangular solve: now uses
a parallel merge/subdivision based algorithm
- speeded up triangular solution of a matrix by multi-vector
- introduced extension BLAS property blas_rsb_autotune_next_operation
to trigger auto tuning at the next USMV/USMM call
- collection/report of time spent in librsb routines now possible (a
simple built-in profiler)
- further Encapsulated PostScript (EPS) matrix rendering options
- improved benchmark program for large parameter studies (converts and
reuses matrices rather than re-reading them from disk)
- binary performance records write/read/combine support, also with
Intel MKL CSR built-in comparison; LaTeX tables output and stats
Source code (LGPLv3 licensed), documentation, change log and extensive
benchmark results available on: http://sourceforge.net/projects/librsb

Thursday 26 November 2015, Satellite Applications Catapult,
Harwell Oxford, UK
Still time to submit! Science and technology play an increasingly
important role in equipping and supporting the armed
forces. Mathematics is fundamental to these disciplines, providing a
framework for understanding and solving the varied and complex
problems faced, and is used to model military systems and scenarios.
These models can be used to estimate system performance, suggest
improvements, or find weaknesses of real systems.
Conference Topics The conference will cover the following themes: Data
analysis: data and text mining, data fusion, information
visualization, multidimensional data analysis; Modelling and
Estimation: electromagnetic models, estimation theory, Markov models,
non-linear models, mathematical models, simulation; Operational
Analysis: cost benefit analysis, counter-terrorism, risk management,
intelligence analysis, behaviour analysis; Security: cryptography and
coding, security systems, secure communications; Signal Processing:
adaptive processing, computer vision, digital signal processing,
distributed sensor processing, emitter location, image processing,
signal enhancement, super-resolution, synthetic aperture radar, time
series analysis; Statistical Methods: Bayesian techniques,
classification, detection, identification, tracking, Monte Carlo
methods, particle filters, pattern recognition.
Papers or posters will be accepted on the basis of a 300-500 word
abstract which should be submitted by 14 May 2015 by e-mail to
conferences@ima.org.uk.

Subject: Graduate Winter School, Geometric PDEs, USA, Jan 2016
The Department of Mathematics at Texas A&M University is offering a
winter school for graduate students on
"Geometric PDEs and Their Approximations".
January 10 - 16, 2016.
Lecturers: Ricardo H. Nochetto (UMD) and Andrea Bonito (TAMU);
January 11 - 16
Deal.II tutorial: Timo Heister (Clemson); January 10
Short Description: A comprehensive approach to the formulation and
discretization of geometric partial differential equation governing
processes will be provided. The topics discussed will center around
differential geometry, calculus of variations, gradient flows and
discretization using finite element methods. Emphasis will be made to
applications and in particular in biophysics and material science.
Afternoon laboratory sessions will serve as numerical illustration to
the topics discussed in the lectures and will provide insights on the
behavior of the algorithms. During these sessions students will have
the choice of using either MATLAB or deal.ii/C++.
Thanks to the support of the US National Science Foundation and the
Institute for Applied Mathematics and Computational Science, funding is
available to support the travel and local expenses for several participants.
We would appreciate if you could forward this announcement to possibly
interested graduate students.

Subject: Postdoc Position, NA/Operations Research, Univ of Pisa
We announce the immediate availability of a fully-funded, one-year
post-doc position at the Department of Computer Science of the
University of Pisa. This position is funded by the research project
"Mathematical models and computational methods for complex networks",
an interdisciplinary effort between the Department of Computer Science
and the Department of Mathematics of the University of Pisa to foster
stricter collaboration between Numerical Analysis and Operation
Research experts for the solution of complex numerical and
optimization problems related to todays' networks (telecommunication,
transportation, energy, social, ...). The candidate should hold a
Ph.D. in Numerical Analysis, Operations Research or Computer
Science. She/he is expected to choose and carry forward about two
different research lines among the several possible ones proposed by
the 14 participants of the project, typically bringing together
aspects of Numerical Analysis and Operations Research, maybe with a
substantial sprinkle of Computer Science thrown in as appropriate. The
participants of the project span several areas of Numerical Analysis
and Operations Research, so finding good matches is not expected to be
hard. Proposing her/his own research lines with analogous
characteristics is also welcome, provided they pick the (varied)
interest of some of the participants to the project. The position is
funded for one year at the standard rate for Italian "assegno di
ricerca" (23336 EUR gross, with low taxation), and some extra money is
available for travel. Candidates of all nationalities are of course
warmly welcome.
Information about application can be found at
http://www.unipi.it/ateneo/bandi/assegni/pra2015/inform. The deadline
for application is May 14, 2015. Interviews with the candidates are
expected to be held on May 28, 2015. Remote interviews are
possible. Formal start of the position is expected on mid June to
beginning of July. Enquiries can be directed to Antonio Frangioni
(frangio@di.unipi.it).
