mhz - calulate processor clock rate
mhz [-c]
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 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.
