Title: Single-chip multiprocessors: a new landscape for computer
architecture and beyond
Professor Guri Sohi
Computer Sciences Department
University of Wisconsin-Madison
The past 25 years have been a very exciting time for computer architecture.
A lot of this excitement was due to new opportunities made available by
semiconductor technology: once basic uniprocessor functionality could be
implemented on a chip, additional transistor resources could be used
for innovative uniprocessor microarchitectures. The microarchitecture of
uniprocessors was totally redefined by this wave of innovation.
The net result is that the microarchitecture of a high-performance
uniprocessor today barely resembles that of one from 20 years ago.
And the rest of the computing community enjoyed continuous increases
in performance in a completely transparent manner.
Today we are at the cusp of another inflection point in computer
architecture. Technology allows for multiple processing cores to be
put on a single chip; the resulting chip resembles a traditional
small-scale multiprocessor. Going further, we expect a revolution in
the architecture and microarchitecture of multicore chips (also know
as chip multiprocessors (CMPs)), as technology advances provide us
with more transistors with which to innovate. This revolution will
encompass almost every aspect of multiprocessing, including new models
for parallelization, new processor microarchitectures that trade off
instruction-level parallelism for thread-level parallelism, new ways
of allowing reliable operation from unreliable hardware components,
and innovative ways of using storage components to architect memory
hierarchies, among others. Unlike the past, however, software will
not be able to reap the benefits of hardware innovation transparently.
Applications and software will have to be more proactive in availing
of the hardware capabilities, and certain types of applications may
be better enabled than others.
This talk will present some initial results towards components of the
overall revolution: innovations in the microarchitecture of multicore
processors and memory hierarchies, and their likely impact on software
and applications.
