Abstract
Achieving petaflop performance across a range of scientific applications
will require not only breakthroughs in computing hardware, but also
innovative advances in systems software, compilers, algorithms, and software
environments. Although the challenges to crossing the petaflop/s barrier
within the next decade are rather daunting, a number of software and
hardware technologies are emerging that could be important to achieving
this goal. This paper reviews these technologies and their current status,
and then goes on to consider in more detail new algorithms capable of
exploiting the architecture of a petascale computer.
