Description:

     A relative performance measure and characteristics of 209 CPUs.

Usage:

     data(cpus)

Format:

     The components are:

     'name' Manufacturer and model

     'syct' cycle time in nanoseconds

     'mmin' minimum main memory in kilobytes

     'mmax' maximum main memory in kilobytes

     'cach' cache size in kilobytes

     'chmin' minimum number of channels

     'chmax' maximum number of channels

     'perf' published performance on a benchmark mix relative to an IBM
          370/158-3

     'estperf' estimated performance (by Ein-Dor & Feldmesser)
