Plasma physics code

Often I read messages from list members asking about the
availability of applications which can make use of the
computing resources of a contemporary Beowulf cluster.
We have a plasma turbulence code which is by now the state-
of-the-art in the MFE (magnetic fusion energy) program.
It was developed solely on Intel-Beowulf clusters, and
runs around the clock on these clusters mostly in an
attempt to break new "physics ground". However, in this
area of physics, the equations are sufficiently complex
that even areas that are viewed by the community-at-large
as "explored" are badly understood (IMO). To this end,
I wonder if anyone wants to devote spare cycles to a
limited version of the solver (really, a very robust
version of the solver with abiabatic electron physics).
The equations are the so-called "gyro-kinetic Maxwell"
equations. The solver is Eulerian. The grid is five-
dimensional. MPI is the MP library. Meaningful runs
will take on the order of days on a 32-64 processor cluster.
Results are made into MPEG-1 movies, presented at
I won't go into further detail -- if anyone is interested,
please send email to:

and we can discuss the conditions. Some simulation MPEGs
