SPEC CPU2000: Measuring CPU Performance in the New Millennium
John L. Henning
Reprinted from COMPUTER, July 2000
As computers and software have become more powerful,
it seems almost human nature to want the biggest and fastest toy you
can afford. But how do you know if your toy is tops? Even if your application
never does any I/O, it's not just the speed of the CPU that dictates
performance. Cache, main memory, and compilers also play a role. Software
applications also have differing performance requirements. So whom
do you trust to provide this information?
The Standard Performance Evaluation Corporation (SPEC)
is a nonprofit consortium whose members include hardware vendors, software
vendors, universities, customers, and consultants. SPEC's mission is
to develop technically credible and objective component- and system-level
benchmarks for multiple operating systems and environments, including
high-performance numeric computing, Web servers, and graphical subsystems.
On 30 June 2000, SPEC retired the CPU95 benchmark
suite. Its replacement is CPU2000, a new CPU benchmark suite with 19
applications that have never before been in a SPEC CPU suite. This
article discusses how SPEC developed this benchmark suite and what
the benchmarks do.
