Project proposed as part of the 1994 Research Experiences for
Undergraduates (REU) Program in High-Performance Computing conducted
by the Northeast Parallel
Architectures Center (NPAC) at Syracuse University. The National Science
Foundation provides primary funding for the 1994 NPAC REU Program, through NSF
Grant CDA-9200577. Additional funding is provided by the Vice President for
Research and Computing, the College of Engineering and Computer Science, the
College of the Arts and Sciences, the Graduate School, and NPAC, Syracuse
University.

- ...difference
- An electric potential difference between
two points is the
amount of work per unit charge which must be done to move the charge
through the electric field that exists between the two points.
- ...gradient
- The gradient is a vector which indicates the rate of change of
a function in the
, 
, and 
directions.
- ...radial
- The
radial component is the distance from the origin in the x, y plane:
.
- ...chaotically
- Chaotic motion is characterized
by sensitive dependence on initial conditions, which renders
it unpredictable in the long run; unlike periodic motion, chaotic
motion never repeats itself.
- ...machine
- HPF is currently implemented at
NPAC on a cluster of DEC
workstations and on the Intel iPSC.
- ...hysteresis
- A common property of
chaotic systems is that transitions occur at
different values depending on the history of the system; this
phenomenon is known as hysteresis.
- ...damping
- Damping effects, which
include friction and laser cooling, decrease the energy of the system.
