SIVO personnel will convene the session, "IN15: Emerging Multi-core
Computing Technology
in Earth and Space Sciences" at the 2008 Fall AGU meeting on December 15–19,
2008, in San Francisco, CA. This session will focus on the issues concerning
the impacts of multi- and many-core processors. Please join us to find ways of
taking advantage of multi-core processors in Earth and Space science applications.

The SIVO Seminar Series presents "Interactive Parallel Computing and
Distributed Arrays in Python" by Peter Stoltz (Tech-X) on Wednesday, July 9,
2008, at 10:00 a.m. The seminar will be an informal "brown-bag" format
and attendees are encouraged to participate in the form of questions, discussions,
and recommendations.
Abstract: The IPython project has been developing an open-source architecture
for parallel computing in Python. This architecture 1) has high-level
interfaces that support rapid development, 2) enables all aspects
of
parallel computing to be performed interactively, and 3) supports
many different models of parallelism. Because IPython is fully
open source and built upon a general purpose programming language
(Python) it provides a simple way for users to integrate their
own existing parallel codes into IPython and use them interactively.
After providing an overview of IPython, I will discuss recent NASA-funded
work implementing distributed
arrays and using legacy Fortran codes in parallel from within this
architecture.

From June 1-13, 2008 13 premier international modeling
groups contributed dynamical cores and modeling mentors for the
National Center for Atmospheric Research (NCAR) Advanced Study
Program Summer Colloquium on Numerical Techniques for Global Atmospheric
Models. SIVO and Goddard Institute for Space Studies (GISS) staff
supported three NASA models, the newly developed Finite-Volume
dynamical core on the cubed-sphere grid, the latitude-longitude
based Finite-Volume dynamical core from the NASA Global Modeling
and Assimilation Office (GMAO) Goddard Earth Observing System Model,
Version 5 (GEOS-5) atmospheric model, and the B-grid quadratic
upstream scheme dynamical core from the NASA GISS ModelE. The colloquium
provided a unique opportunity for selected graduate students from
the atmospheric sciences and applied mathematics to get hands-on
experience with the latest numerical methods for dynamical core
components.

The SIVO Fortran 2003 Seminar Series concludes with"Object
Oriented Programming – Polymorphism in F2003" on Tuesday,
May 20, 2008 at 12:00 PM. In this final session we will cover new aspects of
the standard which enable polymorphism, a powerful abstraction from object oriented
programming. Polymorphism allows the behavior of an "object" (variable)
to vary at runtime without altering other portions of code which used that variable.
Both "class" polymorphism
and a limited form of "template" polymorphism will be addressed.
We will provide detailed examples.
The seminar will be an informal "brown-bag" format and attendees
are encouraged to participate in the form of questions, discussions
and recommendations.

SIVO and the NASA Center for Computational Sciences (NCCS)
are pleased to announce an open house to showcase some of the services
available to NASA's research community. The open house will be
held next Thursday,
the 14th of February from 1:30-3:00pm in the SIVO Scientific
Visualization Studio.
The SIVO team will discuss service offerings
in the areas of visualization and analysis as well as their work
done in support of scientific applications and the modeling community. The
NCCS will highlight some of its compute, archive and service capabilities;
all of which are available to researchers who are supported by NASA's Science
Mission Directorate.
The open house will also include a demonstration of the Scientific
Visualization Studio as well as tours of the NCCS compute and storage facility.
Team members from both organizations will be on hand to assist with any
questions concerning both current and future use of these services. The
beginning portion of this forum will also be made available to remote users
via webcast and telecon. Details can be found at http://www.nccs.nasa.gov/user_forum.html

SIVO is pleased to begin a new biweekly series of seminars
on the new Fortran 2003 (F2003) standard beginning in January
2008.
The F2003 standard is a major update to the Fortran standard it
includes a wide variety of new capabilities of relevance to our
community. Many of these features are now available in virtually
all recent releases of Fortran compilers with others only available
from the more progressive vendors. The content of this series will
emphasize relevance of new features to scientific modeling and
best practices for the use of these new features to ensure clean,
portable software. With the exception of the first session which
will be a general introduction to the new Fortran standard, each
subsequent session will cover a separate subset of the new features
in an informal brown-bag format. The attendees are encouraged to
participate in the form of questions, discussions and recommendations.
SIVO will also maintain a web-based discussion area for these topics.
The first session will be on Tuesday, January
29 at 2:00 PM.
