Accomplishments
We have already made significant progress in several of the areas described
in the overview section.
In particular, we have:
- Developed and released into the public domain a scalable software
package
BlockSolve95 .
which is used to solve large, sparse, symmetric
linear systems. The use of this software package within the two
applications, modeling of vibrational modes of peizoelectric crystals
and high-temperature superconductors, was awarded the 1992 Gordon Bell
Prize for scalable performance.
BlockSolve now has more than 150 external users.
- Designed and implemented a provably fast, highly efficient parallel
adaptive refinement
algorithms
for triangular meshes in two dimensions,
- Created a new
partitioning heuristic that uses geometric
information to equally divide the unknowns across the processors and
reduce the interprocessor communication costs, and
- Collaborated with scientists in other disciplines to solve challenging
application problems
in the numerical modeling of
high-temperature superconductors.
and
piezoelectric crystals on parallel computers.
