Summary: M U LTI CORE COMPUTING
Rumors of the death of Moore's Law are greatly exaggerated, according to a
team of computer scientists from Lawrence Berkeley National Laboratory (LBNL)
and the University of California (UC)­Berkeley. In their view, Gordon Moore's
observation that the amount of computing power packed onto a chip doubles
about every 18 months while the cost remains flat is alive and well. But the
physics is changing.
Industry clung to the single-core model for as
long as possible, arguably over-engineering the
cores to eke out a few percentage points of
increased performance. But the complex core
designs of the past required enormous area,
power, and complexity to maximize serial per-
formance. Now, heat density and power con-
straints have all but ended 15 years of exponential
clock frequency growth. The industry has
responded by halting clock rate improvements
and increases in core sophistication, and is
instead doubling the number of cores every 18
months. The incremental path towards "multi-
