**Subject: New Open-Source Python Textbook**

Dear NA Digesters,

If you have two or three minutes to spend, check out a

new Python programming textbook that is available at

http://femhub.com/textbook-python/.

The book is aimed at high school students, but college

level students who are new to programming can benefit

from it as well. The book contains elements of computational

math and companion Exercise Book and Review Book

are provided.

This is a pilot project to see whether going through

a commercial publisher can be avoided. We do not

see why schools should pay for something that they

can have for free.

BTW, the textbook is written in Latex and it has a public

Git repository "nclab-textbook-python" at Github. Any

contributor becomes automatically a co-author.

It you like the idea, please share the link!

Thank you and best regards,

Pavel

**Subject: Generating and checking units of measure in Fortran**

Dimensions, anyone?

In 1822, Fourier observed that dimensional analysis is important. One

ought not to compare or add apples and oysters, and multiplying length

by area ought to yield volume, not velocity.

Are you eager for programming languages, especially Fortran, to

generate, propagate, and check units of measure? That is, not just

that length and area are different, but so are feet and meters? You

might recall that NASA's Mars Climate Orbiter arrived at Mars 67km

lower than expected, because of an error in units of measure

(pound-seconds that should have been Newton-seconds), at a cost

exceeding $US 300 million.

If you are eager to have such support, now is the time to advocate for

it, at least in Fortran. The US/ANSI Fortran committee is preparing

proposals for incorporation into the next revision of the Fortran

standard, for consideration by the ISO Fortran working group at

meetings in June of 2013 and 2014. I have been advocating

unsuccessfully for this since 1978. Perhaps adding some voices will

improve the prospects.

**Subject: Postdoc Position, LIX, Ecole Polytechnique**

Postdoctoral fellowship on the topic "Optimality for Tough

Combinatorial Hydro Valley Problems" CALL RENEWAL due to some

bureaucracy delays

A postdoctoral position for 12 months, financed by the Fondation

mathematique Jacques Hadamard through the Gaspard Monge Program for

Optimization and Operation Research (see,

http://www.fondation-hadamard.fr/PGMO ) will open at LIX, the

Laboratory for Computer Science at the Ecole Polytechnique (France),

from January 2013 (the position will be open until it is filled). The

project will also involve some researchers from EDF R&D.

In Energy Management, the Unit commitment problem aims at computing

the optimal production schedule for a hydro-thermal energy mix. This

schedule is then executed to meet customer demand in real time the

next day. As such, feasibility of the schedule is a key

requirement. In order to solve the unit-commitment problem efficiently

in finite time, decomposition methods based on Lagrangian relaxation

are employed. These methods then require that various smaller

sub-problems are resolved quickly. One such a sub-problem is

optimization of a hydro valley (on a price signal). When continuous,

such a problem is easily solved to optimality by any current LP

solver. However, the introduction of combinatorial elements as a

result of the quest for feasible schedules, leads to far tougher hydro

valley problems. This is especially true for some of the larger

French Hydro valleys. Indeed, solving some of these up to several % of

optimality might already require several minutes. Multiplying this

with the number of iterations of the global decomposition schedule,

one ends up with too much computation time for the optimization

software to be of operational use. It therefore becomes apparent that

efficient reformulations, or further decomposition should be looked

into. This is exactly the objective of the current post-doc program.

For more details on the project and updates on the position, please

refer to the project web site:

http://www.lix.polytechnique.fr/~dambrosio/PGMO.php

The project involves people from the academia and from EDF:

- Wim van Ackooij, OSIRIS, EDF Research and Development (France)

- Claudia D'Ambrosio, CNRS-LIX, Ecole Polytechnique (France)

- Grace Doukopoulos, OSIRIS, EDF Research and Development (France)

- Antonio Frangioni, DI, University of Pisa (Italy)

- Claudio Gentile, IASI, CNR (Italy)

- Frederic Roupin, LIPN, Paris 13 (France)

- Tomas Simovic, OSIRIS, EDF Research and Development (France)

The candidate should preferably have: a PhD in Operations Research,

Mathematics, Computer Science, Engineering with experience in

mathematical programming, and large-scale mixed integer linear

problems; experience in using and implementing through the most common

OR tools (mathematical programming languages (AMPL/OPL), commercial

and open-source optimization solvers, C/C++ language).

The postdoctoral fellow will work at LIX, Ecole Polytechnique

(www.lix.polytechnique.fr) within the SYSMO team

(http://www.lix.polytechnique.fr/sysmo/) and will interact and

collaborate with all the people involved within the project.

The precise salary is difficult to evaluate. We know the gross salary,

but this also pays for benefits, taxes on the employer's side, taxes

on the employee's side, and revenue tax, which depends on the

individual situation. Experience tells us that the worst case for the

net salary, after all tax, is in the range 1800-2200EUR/month. The

contract comes with funds for buying PCs and for travels.

Please contact Claudia D'Ambrosio (dambrosio@lix.polytechnique.fr) for

questions and to apply for the position.

The required documents (in pdf format) are:

- Detailed CV including a complete list of publications.

- PhD thesis.

- Motivation letter.

**Subject: Postdoc Positions, Lawrence Berkeley National Laboratory**

The Future Technologies Group (FTG) at Lawrence Berkeley National

Laboratory has an immediate opening for two postdoctoral researchers

to work on research in projects to develop, optimize, and deploy

optimized, communication-avoiding sparse linear solvers. This project

will couple traditional performance analysis and optimization arenas

with newly developed variants of the Conjugate Gradient (CG) and

BiConjugate Gradient Stabilized (BiCGSTAB) sparse linear solver

algorithms that minimize data movement and will target supercomputers

built from multi- and manycore processors solving the systems of

linear equations found in AMR Multigrid bottom solvers. As such, the

performance benefits of matrix-free implementations will be evaluated.

Concurrently, this project will parallelize and optimize a newly

developed variant of sparse LU based on a hierarchically semiseparable

representation of the matrix. Deliverables will include both

prototype software distributions as well as publications targeted at

top-tier research conferences.

**Subject: PhD Opportunities, Analysis/Numerics/Probability/Statistics, Warwick**

MASDOC (Mathematics and Statistics Centre for Doctoral Training) is a

4 year graduate programme, 1 year MSc + 3 Year PhD, in Analysis,

Numerics, Probability and Statistics at the Warwick Mathematics and

Statistics Institutes. The four year programme comprises a unique

integraton of innovative taught modules and PhD research of the

highest standard. In their first year students take 6 advanced courses

to deepen their background in these 4 fields, while at the same time

beginning a research project that typically leads on to their PhD

project in years 2-4. PhD projects in MASDOC vary greatly, from Theory

to Methodology to Applications. Students may specialise in one of the

four themes or combine techniques from two or more of the

themes. MASDOC students develop invaluable skills which are applicable

in a broad range of possible careers, from pure academic research

through to scientific modelling in industry.

We offer at least 10 fully funded studentships each year.

The MASDOC Open Day takes place on 21 November 2012; we can reimburse

reasonable travel expenses for students.
