NAME
mhz - calulate processor clock rate
SYNOPSIS
mhz [-c]
DESCRIPTION
mhz calculates the processor clock rate and megahertz. It uses an
unrolled, interlocked loop of adds or shifts. So far, superscalarness
has been defeated on the tested processors (SuperSPARC, RIOS, Alpha).
OUTPUT
Output format is either just the clock rate as a float (-c) or more
verbose
39.80 Mhz, 25 nanosec clock
mhz is described more completely in ‘‘mhz: Anatomy of a
microbenchmark’’ in Proceedings of 1998 USENIX Annual Technical
Conference , June 1998.
