RTIME: Task to test compute times
INPUTS
NCOUNT 0.0 Number of 2-millions of ops
0 => 50
HELP SECTION
RTIME
Type: Task
Use: RTIME is used to relative computer performance. It does
3 operations in floating point and then repeats them in
integer. Each operation has an outer loop repeated
NCOUNT times and an inner loop repeated 2000000 times.
The 1st and 4th loops are simple sums of a constant. The
2nd and 5th loops are sums of
RSUM = RSUM + CONSTA - RSUM / CONSTB
and the 3rd and 6th loops are sums of the form
RSUM = RSUM - RSUM/CONSTB + ARRAY(i) + ARRAY(2000000-i)
Adverbs:
NCOUNT.....The numbers of 2-millions of ops. <= 0 => 50.
