16h30 Sala F-210 Yuefan Deng Stony Brook University Architectures, algorithms, and applications of supercomputers: challenges and solutions
Supercomputers
are capable of performing 1016 floating-point operations per second
(34 PFlops). The greatest challenges facing computer and
computational scientists are to further increase the computer speeds
and, more challengingly,
to develop programming models to enable realization of the potentials
of such massive systems. We
will discuss three related topics. First, we review the latest
innovations in interconnection networks and processor technologies
for achieving ever increasing raw computing speeds. Second, we
analyze a parallel computing algorithm, task mapping, for helping
minimize and balance data movement over a complex network of
processors. Third, we discuss several computational science projects
including study of the mechanisms of human blood platelet
activations, causing heart attacks and strokes, by multiscale
discrete particle dynamics and molecular dynamics.
