02/07/08: Upcoming User Forum
February 14th from 1:30 to 3:30 in Building 28, room S121.
The NASA Center for Computational Sciences (NCCS) and the Software
Integration and Visualization Office (SIVO) 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 in
building 28, room S121.
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 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 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
01/14/08: Seminar Series Announcement: Fortran 2003 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 in B28-E210.

05/01/07: Halem system is now being retired
After almost five years of dedicated service to NCCS community, the halem system is now being decommissioned. As you may know, the Halem system has been without maintenance for over a year. Starting May 1st, this system will no longer be supported. What this
means to the user is that if the system should fail, there will be no attempt
made to recover it. In addition, any disk or licenses which can be used on the
new discover system will be removed without warning. The system will remain
available in this state for a few additional weeks, at which point logins will
be disabled and the system decommissioned.
Users are welcome to continue to use the Halem system under these conditions as
long as it is up and running, just please ensure any data created is
immediately moved to another location.

03/26/07: March 30, 2007 Deadline for moving /nobackup data.
The NCCS is pleased to announce the availability of a new scratch space
for the explore (Altix) environment. This new scratch space comes in the
form of new nobackup filesystems (these filesystems are not backed up by
the system staff). These new filesystems provide expanded space, better
performance and a new pathname scheme that will help differentiate between
other nobackup filesystems on the other compute environments here at the
NCCS. These filesystems are available on all of the Altix systems as well
as on dirac (via CXFS).
Users of the explore environment and dirac can access these scratch areas
via the following path:
/explore/nobackup/
or via the environment variable:
$NOBACKUP
