I am pleased to announce the release of cpuburn-1.3 with
a very much improved `burnMMX` program.
This program now uses the MMX unit to shuffle memory similar
to burnBX as well as doing some math to keep the adders and
multiplier busy. I was very surprised when I had to downclock
my BP6 from 2 * 5.5 * 97 MHz to 94 MHz because of memory errors.
burnMMX appears to be generate more errors than burnBX even
though it generates slightly less memory bandwidth. It
also runs almost as hot as burnP6 when run out of L1 cache
`burnMMX d`. Running from L2 cache `burnMMX f` is the default,
and is also very hot. It should be good for AMD K7 (Athlon,
Thunderbird, Duron) system, although I don't have access to
any of these fine CPUs for proper testing.
Both burnMMX and burnBX now take a letter parameter give finer
control of memory size tested. Other pgms unchanged.
Enjoy,
