The NSCEE has made available to the public four NCD X terminals in the James R. Dickinson library. The X terminals are located in the north-east corner of the second floor computer lab. The terminals provide access to X applications for anyone with an account with NSCEE.
To use the terminals simply enter your login and password at the login screen. This will open a session on the Convex C220, aurora. From there any of the center's resources can be reached.
The NSCEE has established a direct T-1 connection to the Internet through SprintLink. As a result of this, the Internet numbers for all computers managed by the NSCEE will change.
Testing has been completed on the new network connection. On August 11th, the Convex C-220 C, aurora.nscee.edu was moved to the new network segments. Clark and nye were moved shortly after on the 18th. The message of the day on nye will be updated as information about the conversion becomes available.
For those users with domain name service, there will be no impact resulting from this change. However, users who access NSCEE computers by IP number will need to use the new numbers. The following table lists the new IP numbers for the main NSCEE machines.
aurora 199.1.116.3
clark 199.1.115.2
nye 199.1.114.3
The World Wide Web browsing program, Mosaic, is available for public use on any of NSCEE's X terminals located in the James R. Dickinson Library, and the Thomas Beam Engineering Building room B361. Simply login in as user mosaic with the password mosaic. This will startup the mosaic application and allow a user to browse World Wide Web sites. The user will be unable to download or print items from the Web, but the connection is useful for familiarizing yourself with what is available on the net.
The Silicon Graphics workstations at the NSCEE have recently received their long needed upgrade to IRIX 5.2. The new operating system has many nice features like:
The background, or root window, also doubles as a view of a user's home directory. Icons representing files, folders, and devices appear here. This is more like the Macintosh GUI than the Openlook disk tools.
The interface can be set up to remember how you left windows during your previous session. When you log in again, the windows will be as they were. You can also set up the interface so that a default you like will always be used, regardless.
There is a new menu option under the toolbox for showing an overview of the desk. The desk overview is a window that contains icons that represent what is visible on the desk. Each desk is a screen size "canvas" where you place windows and other icons. It is Indigo Magic's representation of a virtual desktop. The icons are interactive, so you can move a window by dragging it around the icon. You can even drag windows between desk icons, and that window will appear on that desk. A big improvement over most virtual desktops is the idea of the global desk. Windows that appear here are shared by all of the desks. Thus, you could have your favorite editor open to all windows at all times.
We are still in the process of rebuilding many of the public domain tools and installing the commercial packages we have come to rely upon. We have installed the latest versions of emacs, flex, bison, gzip, groff, HDF, forms, PVM, and Nekton, to name a few. Many of the packages from SGI, like C++ (called CC, that's uppercase `C', uppercase `C'), impressario, inventor, explorer, and performer have also been installed.
We hope you find your use of our SGI's enjoyable and productive, and if you have any questions, comments, or SGI related bugs or problems, please send e-mail to root@saturn.nscee.edu.
cp $FIDAPROOT/resources/Fidapgl7 $HOME
This command copies the new version of the Fidapgl7 resource file to your home directory. If you have used one of the other resource files provided, rather than the default file Fidapgl7, you should copy the appropriate file to your home directory with the name Fidapgl7.Dr.
Dr. Yuan's main research interests are in the remote sensing and
GIS applications in environmental monitoring and computer and
mathematics applications in earth sciences. Dr. Yuan has been the key
participant of U.S. EPA's North American Landscape Characterization
project. He has developed a number of techniques for multitemporal
image normalization and change detection. Now Dr. Yuan is teamed with
NSCEE scientists working on research projects that involve prototyping
remote access of remote sensing data, evaluating scientific
visualization tools for environmental data, and developing an
intelligent classification system for remote sensing data.
Richard Marciano joined NSCEE on August 1, 1994 in the capacity of
Computational Scientist.
Richard Marciano joined NSCEE on August 1, 1994 in the capacity
of Computational Scientist. He joins the User Support Division and
will be responsible for assisting NSCEE users in their research,
providing help with application codes, algorithm development, training
with application software, code optimization, and training in parallel
and distributed processing.
Richard has been involved with scientific program development, scientific data visualization, and parallel and distributed computing for over seven years. He completed his Ph.D. in computer science from the University of Iowa in 1992, specializing in parallelizing compilers, and holds a Master's Degree in Electrical Engineering.
Richard worked as a supercomputer and parallel processing research consultant for the "Advanced Research Computing Services" group at the University of Iowa. In that capacity he wrote technical reports, developed and taught a series of short courses and seminars on parallel programming, conducted collaborative research, and published extensively.
He has developed codes on: (1) distributed systems like the 64 processor Intel iPSC/860, the 128 processor Kendall Square Research machine (KSR), and networks of heterogeneous workstations using Network Linda and PVM; (2) data parallel systems like the 16K processor Goodyear Aerospace Massively Parallel Processor (MPP), the 32K processor Connection Machine (CM2) at the Pittsburgh Supercomputer Center and 128 processor CM5, the 16K processor MasPar MP-1 and 4K processor MP-2 at the Ames Scalable Laboratory; (3) Cray systems (Cray X-MP, 2, Y-MP, C90); (4) shared memory machines like the 20 processor Encore machine, 8 processor Alliant FX-8 and 24 processor Alliant FX-2800.
In March of 1993 Richard won the First Prize in the MasPar Supercomputing Challenge, an international supercomputing programming contest organized by MasPar Corporation. Richard also conducted work at the four National Supercomputing Centers (Cornell, Pittsburgh, San Diego, Illinois) and NCAR, and has been working with the staff at Cornell to evaluate parallel platforms and parallel debugging tools.
