Hi John, Here is the 2-cpu AlphaServer ES45 at 1000 MHz. This run uses the same binary as the 4-cpu run (mailed separately). -john Script started on Tue Jun 5 11:05:25 2001 % /usr/sbin/psrinfo -v Status of processor 0 as of: 06/05/01 11:05:32 Processor has been on-line since 06/05/2001 11:02:37 The alpha EV6.8CB (21264C) processor operates at 1000 MHz, has a cache size of 8388608 bytes, and has an alpha internal floating point processor.
