Subject: Re: Fortran vs Matlab
In the same spirit as Tim Davis' enumeration a few weeks back of sparse direct
solver packages written in Fortran vs C/C++, let me also add a few data
points in other areas:
- In sparse linear algebra, the two acknowledged heavyweight Open Source
packages at this time are PETSc and Trilinos. The first is written in C, the
latter mostly in C++.
- Among the more widely used packages that support finite element computations
beyond a single application, I would count DiffPack, PLTMG, deal.II,
FreeFEM++, libmesh, OOFEM, in addition to many others of varying degree of
distribution and open sourceness that could be listed here. Of the ones
listed, only the oldest one (PLTMG) is written in Fortran, all others in
C++. As far as I know, the more modern and more general frameworks that
supersede individual application-specific codes written in the national labs
are also written in C++.
It may be true that there is a large amount of legacy code written in
Fortran out there. However, all the codes listed above also have several
100,000 lines of code and are in no way immature recent inventions. It
therefore seems to me that by teaching Fortran instead of a more modern
programming language, we prepare our students more for conservation of old
codes than for the more far sighted maintenance and creation of current
and future codes.
The issue of Matlab vs compiled languages is a separate one to which
others have already contributed.

Subject: Re: those poor indices (Fortran vs MATLAB discussion)
Regarding Louis Komzsik's comment about Fortran vs MATLAB, and the use of
indices: in my domain (sparse matrix algorithms) we use indices all the time.
There comes a point, however, when indices get in the way, and a higher level
of abstraction is critical.
For example, [L,U,p]=lu(A,'vector') or p=amd(A), both in MATLAB, return a
permutation vector p. For LU, A(p,:)=L*U is computed. This is an index-free
statement. Similarly, a FEM matrix should be considered a sum of cliques, not
as a collection of scalar ij's.
Inside, these codes are chock full of index computations. When I read (or
write) comments in code near where all these indices are flying around, I see
higher level objects being discussed ("compute the set union of clique a and
clique b", "traverse the path from i to e", etc). Scalar "ij" comments do not
abound, even though scalar ij's abound in the code.
I interpret the statement "indices rearing their ugly heads" as the common
problem of introducing scalar indices too early. At some point they are
needed (in thought, in teaching, and in code) but they should always be kept
at the highest level of abstraction possible.

Subject: LaSCoG 3rd Workshop on Large Scale Computations on Grids, Sept 2007
PRELIMINARY CALL FOR PAPERS
3rd Workshop on Large Scale Computations on Grids
Gdansk, POLAND,
September 9-12, 2007
http://lascog07.info.uvt.ro/
Large Scale Computations on Grids (LaSCoG) Workshop will be held in
conjunction with the Seventh International Conference on Parallel
Processing and Applied Mathematics (PPAM 2007, http://ppam.pcz.pl).
The emerging paradigm for execution of large-scale computations, whether
they originate as scientific or engineering applications, or for
supporting large data-intensive calculations, is to utilize multiple
computers at sites distributed across the Internet. In particular,
computational grids are collections of distributed, possibly
heterogeneous resources which can be used as ensembles to execute
large-scale applications. While the vision of the global computational
grid is extremely appealing, there remains a lot of work on all levels
to achieve it. In this context the LaSCoG workshop is envisioned as a
forum to promote exchange of ideas and results aimed at addressing
complex issues that arise in developing large-scale computations on
grids and running applications on them.
Covered topics include (but are not limited to) grid-focused aspects of:
* Large-scale algorithms
* Symbolic and numeric computations
* High performance computations for large scale simulations
* Large-scale distributed computations
* Agent-based computing
* Data models for large-scale applications
* Security issues for large-scale computations
* Science portals
* Data visualization
* Performance analysis, evaluation and prediction
* Programming models
* Peer-to-peer models and services for scalable grids
* Collaborative science applications
* Business applications
Paper submission and publication:
* Papers will be refereed and accepted on the basis of their scientific
merit and relevance to the Workshop topics.
* Papers presented at the Workshop will be included in the Conference
Proceedings and published after the conference by Springer in the LNCS
series (http://www.springer.de/comp/lncs)
* Authors should submit papers (as PDF files) by e-mail to Dana Petcu
(petcu@info.uvt.ro) before April 30, 2007.
* Papers are not to exceed 8 pages and have to be prepared using LNCS
style (http://www.springer.de/comp/lncs/authors.html).
* Extended versions of selected papers will be published in a special
issue of a journal (to be announced later).

Cardiff University, UK.
Duration: 3 years
Project: Modelling of Mantle Convection.
This is an interdisciplinary research project funded by the Leverhulme
Foundation involving the Schools of Mathematics and Earth Sciences at Cardiff
University. All of Earth’s geological activity, including plate tectonics,
earthquakes, volcanism and mountain building, is ultimately driven by
convection in the mantle. To better understand this activity we need a means
to realistically model the mantle’s convection. While there have been recent
significant advances in modelling mantle convection, no realistic models exist
in spherical geometry which mimic both plate tectonics and temperature
dependent viscosity at Earth-like vigour. The primary objective of this
project is to develop a robust implementation of temperature dependent
viscosity, stable at Earth-like vigour. A secondary objective is to
incorporate more sophisticated rheology for the cold near surface boundary
layer to generate self-consistent plates. The ability to have self-forming
plates is absolutely critical for correctly modelling mantle dynamics.
Applicants should have a PhD, or be close to completion, in geophysics,
applied mathematics, engineering or equivalent. The ability to write
numerical software is essential
