Subject: PRIMME Eigensolver

PRIMME: PReconditioned Iterative MultiMethod Eigensolver

We are pleased to announce the release of PRIMME Version 1.1 featuring
enhanced functionality and a year-long testing by several groups.

PRIMME is a C library for the solution of large, sparse, real
symmetric and complex Hermitian eigenvalue problems. It implements a
main iteration similar to Davidson/Jacobi-Davidson, but with the
appropriate choice of parameters it can transform to most known, and
even yet undiscovered, preconditioned eigensolvers. These include the
nearly optimal GD+k and JDQMR methods.

PRIMME implements one of the most comprehensive sets of eigenvalue
techniques, including block methods, locking, locally optimal
restarting, dynamic stopping criteria for inner iteration, and many
correction equation variants. Coupled with the above nearly optimal
methods, PRIMME demonstrates exceptional robustness and efficiency.
Even without preconditioning, PRIMME has proved faster than Lanczos
methods for a small number of eigenpairs of difficult problems.

PRIMME's multi-layer interface allows non-expert, end-users to access
the full power of these methods. Unlike traditional Jacobi-Davidson
methods, where a host of parameters must be tuned, PRIMME has a
sophisticated mechanism for determining appropriate defaults.
Moreover, under a new DYNAMIC mode, the best method can be selected
dynamically based on runtime timings and measurements. Yet, experts
can still control and experiment with numerous tuning knobs.

PRIMME works with any external matrix-(multi)vector and preconditioner
(multi-)vector functions, including indefinite preconditioners; it can
find both exterior and interior eigenpairs; it is both sequential and
parallel (SPMD parallelization); and can be called from any C, C++, or
Fortran program.

Computational Methods with Applications
(Harrachov 2007),
August 19-25, 2007, Harrachov, Czech Republic

Following two previous meetings in computational methods with
applications held in Milovy, Czech Republic in the years 1997
and 2000, we will organize from August 19th to 25th, 2007
the third meeting under the name Harrachov 2007.

The program will be planned for full five days Monday through Friday
(arrival Sunday afternoon, departure Saturday morning) with Wednesday
afternoon devoted to a trip. Thursday afternoon and Friday will be
mostly devoted to lectures of the special event:

The 6th GAMM Workshop on Applied and Numerical Linear Algebra

coorganized with GAMM. The meeting will be held at the hotel Sklar
which is located in the Giant Mountains, approximately 100 kilometers or
65 miles North of Prague (transportation on August 19th and August 25th
will be provided by conference buses).

As in the previous meetings, the program concentrates on computational
methods, namely on methods of numerical linear algebra, their
sequential and parallel implementations and related applications.
Since a considerable part of such applications arise from numerical
solution of partial differential equations, we will support interactions
with application fields by partnership with the series of meetings
ALGORITMY organized by the Faculty of Civil Engineering,
Slovak University of Technology, Bratislava, and by collaboration with
the Necas Center for Mathematical Modelling, Charles University in Prague.

Research Center CRC540 "Model-based experimental analysis of kinetic phenomena
in fluid multi-phase reactive systems". Within this CRC we want to employ a

scientific researcher (PhD or Postdoc).

The position gives the opportunity to work in a highly motivated
interdisciplinary team on a topic on the cutting-edge of applied mathematics
and scientific computing.

Project summary: The project concerns the development and implementation of
numerical methods for the simulation of two-phase incompressible flows. The
candidate becomes a member of a team that is working on the development of a
solver (DROPS, cf. that is used for the
numerical simulation of two-phase flows that are considered in CRC540.

Subject: PhD studentship at the University of Reading (UK)

Changing coastlines: data assimilation for morphodynamic prediction and

A PhD studentship is available in the Department of Mathematics at The
University of Reading,UK, to work on data assimilation for coastal
prediction and monitoring.

The topography of the sea floor, generally known as the bathymetry,
evolves over time as sediment is eroded, transported and deposited by
water action. Improved accuracy of current and predicted future coastal
bathymetry would allow improved flood forecasting, construction of
better sea defences, better management of coastal habitats, and better
understanding of the effects of changes in land use near the coast.

Morphodynamics is the study of the evolution of the bathymetry in
response to the erosion and deposition of sediment. Coastal
morphodynamics presents a challenge to modellers. Observed bathymetric
samples typically only provide partial coverage of the domain of such a
model. Hence, initialisation of such models using only a set of recent
observations is not feasible. The effective and efficient use of limited
data, such as these, requires state-of-the-art mathematical, statistical
and computational methods, known as data assimilation techniques. This
project will use data assimilation techniques with a coastal sediment
transport model to answer questions regarding the uncertainty and
predictability of such a model and to design an optimal observation
strategy for coastal monitoring.

The studentship is available commencing 1 January 2007, or as soon as
possible thereafter. For further details about the project please see
