iForth (and tForth) have them, since about 1998.

#100000000 VALUE #runs
0 VALUE sum1
#1024 ALLOT ( you figure it out :-)
0 VALUE sum2

: PERF ( -- )
	PAR
	 STARTP  #runs 0 ?DO  1 +TO sum1  LOOP   ENDP
	 STARTP	 #runs 0 ?DO  2 +TO sum2  LOOP   ENDP
	ENDPAR
	sum1 sum2 + ." sum = " . ;

The two STARTP's run on different cores. And yes, PERF runs twice as fast
as the same computation on a single core.
