I was curious to note that there did not appear to be any laptop results (some
of us wind up running fairly heavy code on our laptops :} since while docked
they're also our office machines).
Anyway, the system is a Dell Latitude CPx, 500 MHz Mobile PIII, Intel Mobile
440BX, 128MB 100MHz SDRAM, running the standard NT executable (wstream.exe).
Results (347; 337; 412; 407) are within experimental error of Mason Cabot's
numbers for "BX Katmai 600/100" (342; 340; 412; 409), indicating that whatever
changes Intel made for the Mobile 440BX didn't affect any of the core
performance paths.
-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 999936
Total memory required = 24.9 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 38035 microseconds.
(= 38035 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.
