multicore processors in DOS (Developers)

Japheth wrote an example of DOS long 64 bit EXE,
But has anobody tried to create a DOS program using more CPU cores?
Something like "Hello from core 0" -- "Hello from core 1"

Because I don't see any benefit from 64 bit mode in DOS but I could imagine some from using of two CPU cores. (like one for TSR, another one for program)

Well I forgot the HX feature - delete this

Long story short, Japheth has/had an example and did some work for HX, but it got scrapped due to his legal (?) concerns.

Indeed: 7-ZIP or some other compression :-)

What does your TSR do that it needs that much CPU ???

Japheth's 4486 (2008-Jun) apparently didn't work :-|

(I don't need it that badly, removing some bugs would be maybe a better idea ...)
