xlf 2.1 pre-processor experience?

[Vic Abell]

I would be interested to hear others' experience with the Fortran
preprocessor in xlf 2.1.  My experience so far has been that two
local codes each got about a 10% speed improvement, while two
benchmarks (Linpack and Whetstones) each got a much higher boost.


			xlf 1.1			xlf 2.1
						+ preprocessor

Local code 1		43 CPU sec.		39 CPU sec.
Local code 2		1001 CPU sec.		910 CPU sec.
Linpack			13 MFLOPS		18 MFLOPS
Whetstones		33,000 Whetstones/sec.	49,000 Whetstones/sec.

(I used the "-P -Wp,-ew" options to xlf.)
