An Overview of High Performance and Grid Computing.

Jack Dongarra

In this talk we will look at how High Performance computing has changed over
the last 10-year and look toward the future in terms of trends. In addition,
we advocate the  `Computational Grids' to support `large-scale' applications.
These must provide transparent access to the complex mix of resources  -
computational, networking, and storage - that can be provided through
aggregation of resources. The vision is of uniform, location independent, and
transient access to the

resources of contemporary research activity in order to facilitate the
solution of large-scale, complex, multi-institutional/multidisciplinary data
and computational based problems. It envisages these resources being
accessible through a Problem Solving Environment appropriate to the target
community.
