SUMMARY:
Thanks to all respondents, especially to Victor Fieldhouse for sending
me a copy of the SPEC FAQ. This can be retrieved by anonymous ftp
(file://ftp.nosc.mil/pub/aburto/spec.faq). Anyone wanting information
on SPEC would do well to begin with the FAQ. Basically, the SPECrate
int and fp are produced from a suite of benchmarks which are
themselves measures of CPU, memory, and compiler code generation
performance. Disk and other I/O effects are negligible factors.
