Computing in Chemical Engineering Award for work using intervals
Professor Mark Stadtherr from Notre Dame University has won this award
for his work in solving nonlinear problems in computational chemistry. In
part, this work was funded by Sun as part of the interval R & D projects.
For more information, see:
1) press
release and
2) talks given by Mark's students at the award banquet:

-
Applications exploiting the parallel structure of interval algorithms for
solving nonlinear systems and global optimization:
slides
and
pres. record.
The two example problems
used here are not that interesting in themselves (because if one is clever
they can be done fairly fast on a serial machine), but the superlinear
speedups seen in some cases were impressive (speedup of about 40 on 2
processors; of over 100 on 16; etc.). The student (Tony Gau) is using an
asynchronous diffusive load balancing strategy, which is not subject to the
bottleneck effects that can occur in a master-slave scheme.
