Subject: ProtoMol, Software for Molecular Dynamics

We are pleased to announce the release of ProtoMol v2.0: a free, open
source, object-oriented, component-based framework for molecular dynamics
(MD) simulations. It supports CHARMM 19 and 28a2 force fields and is able
to read and write PDB, PSF, XYZ, DCD, and several common graphics formats.
ProtoMol is designed for high flexibility, ease of extendibility and
maintenance, and high performance and scalability demands. We use MPI to
implement atom- and force-based decompositions in a manner nearly
transparent to both end-users and developers. The use of fast
electrostatic force evaluation algorithms like particle mesh Ewald (PME),
an O(n log n) method, and multigrid summation (MG), an O(n) method,
further improve performance.

ProtoMol contains many novel MD and Monte Carlo (MC) based methods
suitable for simulation in a variety of ensembles. For example, shadow
hybrid Monte Carlo (SHMC) has been shown to scale with system size and MD
timestep by a factor of 10 or more over hybrid Monte Carlo (HMC).
Multiscale simulations take advantage of longer timesteps by coupling
multiple time-stepping algorithms with advanced integrators. Using
targeted Molly, we have achieved stable timesteps of 16fs for solvated
proteins. In addition, ProtoMol has been designed to interact with VMD, a
visualization engine developed at the University of Illinois, which is
used for displaying large biomolecular systems and running simulations in
3-D.

Highlights of ProtoMol v2.0:
- Average 50% performance increase versus ProtoMol 1.8.3
- Novel integrators including Shadow Hyrid Monte Carlo (SHMC),
isothermal-isobaric MD, and isomolar-semigrand MD.
- An updated interface for adding new forces, integrators, and output methods
- Improved code organization utilizing design patterns

We invite you to visit the ProtoMol home page,
http://protomol.sourceforge.net, where C++ source code, documentation, and
prebuilt binaries may be found. Operating systems natively supported
include Linux, SunOS, Irix, HP-UX and Windows.

We have also configured a new mailing list to better serve our user base.
Please visit the following link and join the list for support and
development news:

Protomol user and development questions can be sent to the list using the
following email address:

Subject: Special Issue on Real Numbers

The dead-line has been postponed to June 15th 2005

REAL NUMBERS
Special issue of the journal

Theoretical Informatics and Applications
http://www.edpsciences.org/journal/index.cfm?edpsname=ita

Guest editors: Vasco Brattka, Christiane Frougny, Norbert Mueller

Efficient manipulation of real numbers in computers is still a
challenge. Many interesting theoretical and algorithmic problems are
linked with that topic and belong to quite distant fields such as
computer science, number theory, numerical analysis, computer algebra
and logics. Several special issues on real numbers and
computers have been previously published in the journal Theoretical
Computer Science, as follow-up to the RNC meetings on these topics.

The last meeting was RNC6 which took place in Dagstuhl, Germany,
in November 2004, see
http://cca-net.de/rnc6/

However, this call for papers is open to authors who did not attend RNC6.

TOPICS
Scientists working on questions related to real computer arithmetic
are encouraged to present the theoretical or algorithmic aspects of
their results, even if they did not attend the RNC6 conference. Survey
and tutorial articles may be suitable if clearly identified as
such. Topics include (but are not restricted to) the following list:

* Foundation and properties of number systems
* Computability and complexity
* Formal aspects and automatic proof checking
* Links with number theory and automata theory
* Basic arithmetic operations
* Implementation of the standard and special functions
* Engineering of floating and fixed point algorithms
* Symbolic manipulation of numbers
* Accuracy and reliability for applications and industry
* Robust geometric algorithms and exact geometric computation
* Hardware design support and implementations

HOW TO SUBMIT
Prepare a PostScript or PDF version of your full 10-20 pages paper
preferably using the latex style
LaTeX2e class for RAIRO -Theoretical Informatics and Applications
ftp://ftp.edpsciences.org/pub/ita/.

The file should be sent by e-mail to Christiane.Frougny@liafa.jussieu.fr
before June 15th 2005.
