And HP hasn't mix/matched processor clock frequency's in one box either.
870 (4-way/PA1.0/CIO) I think had something funny about the clocks which
I think was repeated in the T-class and possible planned in newer
architectures. Can anyone shed more light on this?
Minimizing clock drift of the various processors in an SMP box is
a difficult problem. Keeping accurate time is important but
synchronization of processors too often can really hurt performance.
