NIMROD
The principal goal of the NIMROD project
is to develop a modern computer code suitable
for the study of large-scale (order of the machine size) physics in realistic toroidal
geometry in Tokamaks, Spheromaks, Reversed Field Pinches, and Field-Reversed Configurations.
The project makes use of a mult-disciplinary, multi-institutional team to make
the NIMROD code easily accessible to a wide variety of fusion scientists of differing
levels of theoretical and numerical expertise. NIMROD is an acronym for Non-Ideal
MHD with Rotation: Open Discussion.
The Collaboratory intends to hold demonstrations of new capabilities at the
annual Sherwood meeting (April 22-24, 2002 Rochester NY), the annual APS/DPP
meeting (November 11-15, 2002 Orlando FL), and the annual SuperComputing
meeting (November 17-22, 2002 Baltimore).
Note that the NIMROD code is not meant to be run between tokamak pulses.
Instead, it is intended to always be pushing to the largest computers available to
do even more complex physics.
Advanced Scientific Visualization Applications for NIMROD
The main issue here is how to make applications that are extensible
by more than just a few computer science experts. What happens when a
new piece of physics needs a new visualization - who can do the work?
To make this co-development project work the NIMROD team agrees to take
the time to talk with the collaboratory people to define their needs and
to try the new tools providing critical feedback.
Remote Visualization
The core NIMROD team that will be involved in the remote visualization work of
the Collaboratory is listed below. Note that Schnack and Kruger can come to General
Atomics to participate in remote team working meetings and possible use the new tiled
display wall. There would be typically a total of 5 people at GA participating in this meeting.
- Carl Sovinec & graduate student, U. of Wisconsin, 1500 Engineering Drive, Madison, WI
- Scott Parker & graduate student, U. of Colorado, CB 390, Boulder, CO
- Rick Nebel, LANL, K-717, Los Alamos, NM
- Dalton Schnack & Scott Kruger, SAIC, 10260 Campus Point Drive, MS W2M, San Diego, CA
- Eric Held, Utah State University, SER Building, Logan, UT
- David Schissel, General Atomics, 3550 General Atomics Court, Building 13, San Diego, CA
Types of Remote Interactions:
- Team working meetings where the core group will discuss physics and coding issues using
interactive visualization.
- One on one interaction: (a) shared debugging which involves interactive visualization and lines of code,
(b) shared visualization to discuss physics.
The visualization applications and software used during the working group meetings should be applicable
to tiled display walls. Participants coming to General Atomics could use a wall. Do others have walls
on site that they might be able to use? Does it make any sense with CRT monitors so inexpensive to buy
several and have a personalized wall?
