Subject: libflame 4.0 now available
We are happy to announce the fourth milestone release (r3815) of
libflame, a modern replacement for the most-used functionality of the
LAPACK linear algebra library.
Some improvements since version 3.0:
- Algorithms-by-blocks for two new operations: (1) LU with partial
pivoting, and (2) Up-and-downdating an upper triangular Cholesky or QR
factor. These new implementations join existing algorithms-by-blocks
for Cholesky factorization, QR factorization via the UT transform, LU
factorization via incremental pivoting, Triangular matrix inversion,
and SPD/HPD matrix inversion.
- New advanced scheduling options for SuperMatrix, libflame's runtime
task scheduling and SMP/multicore parallel execution system.
- A preliminary implementation of a new BLAS-like interface layer,
BLIS, which attempts to remedy deficiencies in the original BLAS
interface, particularly with regard to conjugating (without
transposing) certain matrix and/or vector operands.
- Column-major and row-major storage support for nearly all routines.
- Optimized unblocked C routines for nearly all LAPACK-level operations.
- Independence from LAPACK.
- Independence from Fortran; all libflame code is now written in C and
thus a Fortran compiler is no longer needed to build the library.
- User-friendly solve routines that compliment their corresponding
factorizations.
- Improved support for building under Microsoft Windows (including
Windows 7).
- More robust error checking.
- Continued support for an LAPACK compatibility layer.
For a first introduction to libflame we recommend reading:

S. Quintana-Ortν, and Gregorio Quintana-Ortν. "Introducing: The

Subject: Stephen Smale Prize - call for nominations
The first Stephen Smale Prize will be awarded in the meeting
Foundations of Computational Mathematics (FoCM) in Budapest in July
2011, http://www.damtp.cam.ac.uk/user/na/FoCM11/.
We hereby call for nominations of candidates. Nominations should be sent
by email to the secretary of FoCM
Hans Munthe-Kaas, hans@math.uib.no
Deadline: October 3, 2010.
Full announcement of prize here: http://www.focm.net/smaleprize.pdf .
BACKGROUND: The Society for the Foundations of Computational
Mathematics (www.focm.net) was created in the summer of 1995,
following the month-long meeting in Park City, Utah, which was
principally organized by Steve Smale. The Park City meeting aimed, in
Smale's words from the preliminary announcement, ``... to strengthen
the unity of mathematics and numerical analysis, and to narrow the gap
between pure and applied mathematics." Smale's vision has been the
Society's inspiration these past 15 years. During this period the
journal 'Foundations of Computational Mathematics' was created,
several colloquia and research semesters were organized and six
international conferences were held in what has become a triennial
series. The Budapest meeting in 2011 will be the seventh.
After fifteen years of existence, with an established and recognized
position in the scientific community, the Society has created the
``Stephen Smale Prize" whose objective is to recognize the work of a
young mathematician in the areas at the heart of the society's
interests and to help to promote his or her integration among the
leaders of the scientific community. The first Stephen Smale Prize
will be awarded at the Budapest meeting.
RULES (summary, see www.focm.net/smaleprize.pdf for full details):
* The goal of the Smale Prize is to recognize major achievements in
furthering the understanding of the connections between mathematics
and computation, including the interfaces between pure and applied
mathematics, numerical analysis and computer science.
* To be eligible for the prize a candidate must be in his or her early
to mid career, meaning, typically, removed by at most 10 years of
his/her (first) doctoral degree by the last day of the FoCM meeting
(July 14, 2011). Allowances might be made for atypical life
circumstances.
* Eligible candidates should be nominated (self-nominations excluded)
by sending an email to the secretary of FoCM, Hans Munthe-Kaas,
hans@math.uib.no no later than October 3, 2010. Each nomination
should be accompanied by a brief case for support. There is no
compulsory format for the nomination but it should include at least
three letters of recommendation.
* The recipient of the prize will be expected to give a lecture at the
meeting. A written version of this lecture (tagged as the Smale Prize
Lecture) will be included in the volume of plenary talks.

and about the subject description at these links:
http://www.cnes.fr/web/CNES-en/7432-topics-2009.php?view=item&item=2285
Subject short description :
The candidate will contribute to the development of autonomous orbital
rendezvous guidance algorithms in the general framework of the model
predictive control techniques. To provide rendezvous guidance algorithms
with robustness property, an intuitive idea frequently used in the space
industry consists in the following iterative procedure:
1. Generating a constrained maneuvers plan that leads the deputy vehicle
to reach a final relative state in fixed time from its current state at
the time t0.
2. Performing the first maneuver of the plan at the time t1 > t0.
3. Estimating the new current relative state at the time t2 > t1 (e.g.
just after performing the first maneuver).
4. From this new state, generating a new plan of maneuvers to reach the
target, and return to Step 2.
Although this heuristic method looks like a closed loop strategy, it is
not based upon a formal and rigorous analysis that solely ensures
stability and robustness with respect to uncertainties and allows
performances quantification.
To cope with these issues, we intend to tackle the guidance problem in
the general framework of the model predictive control (MPC) techniques.
Albeit these methods take up the reasoning described above e.g.
optimizing control actuation under constraints on a receding horizon
they are mainly designed to take advantage from the feedback pieces of
information about the gap between nominal and actual positions and also
from the control sequence itself so that it becomes possible to online
adapt the control law, soften the constraints or even evolve the model
used in the algorithm. It is noteworthy that the feedback concept used
in this framework is set upon a specific control structure, adaptive or
not, for which the cost function which quantifies the rendezvous
accuracy will be an influent factor on the stability of the whole
system. The prospective nature of this way of investigation consists in
replacing the previous heuristics by a formal approach that sets the
stability, ensures robustness against uncertainty and provides good
online performances.
Requirements:
For thesis contracts, university candidates or graduates of a Grande
Ecole or engineering school must hold a Master 2 degree awarded by a
university, or a suitable degree enabling them to enrol for their thesis
at the relevant doctoral school. To this subject, knowledge on space
relative dynamics and control techniques will also be appreciated.
Application:
The application deadline is 31th of March 2010 . The successful
candidates might be selected for an interview process in spring and have
to be available for a start between September and December 2010.
