Subject: The union of libflame and LAPACK

Sponsored by an NSF Software Infrastructure for Sustained
Innovation grant, we have been developing a new, vertically
integrated dense linear algebra software stack. At the bottom of
this software stack is the BLAS-like Library Instantiation Software
(BLIS). Above this, targeting sequential and multithreaded
architectures is libflame. At the top of the stack is Elemental
for distributed memory architectures.

libflame targets roughly the same layer as does LAPACK, and now we
have incorporated the LAPACK code base into libflame. For those
operations where libflame has the native functionality, the LAPACK
code becomes an interface. For all other operations, the netlib
implementation provides that functionality. We affectionately call
this new union "flapack", which offers the following benefits:

1) The libflame implementation of LAPACK is entirely coded in C.
No Fortran libraries or compilers are required.
2) The libflame library builds upon the BLIS interface. This
interface, unlike the BLAS, allows for arbitrary row and column
stride. While some applications may benefit from this (e.g., those
that perform computation with slices of tensors), from a
development and maintainability point of view it allows more
functionality to be supported with less code.
3) The union of the two libraries allows users to benefit from both
the LAPACK and libflame code base, within one package.
4) "flapack" passes the LAPACK test suite on platforms where we
have tested this. (There is one exception of a test case that
involves packed matrices that we believe is not in general use.)

The library is available under a 3-clause BSD license at:

9th Doctoral Workshop on Mathematical and Engineering Methods in
Computer Science, MEMICS 2014
October 17--19, 2014, Telc, Czech Republic

Since 2005, the aim of MEMICS is to provide a scientific forum for
doctoral and master students interested in applications of
mathematical and engineering methods in computer science. Besides a
rich technical programme (including invited talks, regular papers, and
presentations), MEMICS also offers friendly social activities and
exciting opportunities for meeting like-minded people.

MEMICS submissions are traditionally invited from all areas of
computer science. In line with the tradition of MEMICS, several
different areas are, however, given a special focus each year. In
2014, these areas are:
- Algorithms, logic, and games.
- High performance computing.
- Computer-aided analysis, verification, and testing.
- Hardware design and diagnostics.
- Computer graphics and image processing.
- Artificial intelligence and natural language processing.

Participation: Students are invited to submit a regular paper or a
presentation. A regular paper is a previously unpublished original
work, not exceeding 12 pages in the LNCS style.

deconvolution/signal separation, broadband systems, compressed
sensing and novel sampling schemes. The aim of the conference is to
bring together mathematicians, statisticians and engineers with a
view to exploring recent developments and identifying fruitful
avenues for further research. It is hoped that the meeting will
help to attract more mathematicians into this important and
challenging field.

Contributed papers are invited on all aspects of mathematics in signal
processing and will be accepted on the basis of a 300-500 word
abstract which should be submitted by 30 June 2014 by e-mail to Authors will be advised of acceptance by 31
July 2014. Successful authors will be invited to submit a four page
paper for inclusion in the conference proceedings by 7 November 2014.

Subject: Inverse Problems and Optimal Control, Hong Kong, Dec 2014

International Conference on Inverse Problems and Optimal Control,
The Chinese University of Hong Kong,
December 4-6, 2014

Inverse Problems has become a very active, interdisciplinary and
well-established research area over the past two decades, the same as
Optimal Control. Both areas are closely related to each other and have
found wide applications in engineering, industry, medicine, as well as
life and earth sciences. This international conference aims to
provide a forum for researchers from the world to present and exchange
their latest research achievements on Inverse Problems and Optimal
Control, as well as their applications. It also aims to promote
collaborative research on Inverse Problems and Optimal Control between
China and the rest of the world. This conference will encourage
international collaboration and interactive activities on Inverse
Problems and Optimal Control and provide an opportunity for young
researchers to learn the current state of the art in the fields and
present their recent research results as well.
