a problem about compilation on SUN & SGI# Unix - 噫吁兮，危乎高哉
s*s
1 楼
I have F77 codes. On SGI Indigo2 R10000,
the comilation option in makefile is -O -mips4.
It ran very well.
But when I move to SUN blade2000,
I use comilation option:
-fast -xprefetch -xtarget=ultra3 -xchip=ultra3 -fns=yes -fsimple=2
it could pass compilation and generate excutable file. but when I run
it, it always show the fowlling info at the end:
Note: IEEE floating-point exception flags raised:
Inexact; Underflow;
Nonstandard floating-point mode enabled
See the Numerical Computation
