Hi Guys:
I have a question about running the same program (written by
Fortran 77)in different platform using different compiler. In Linux
platform, I run my program compiled by PGF77 and in Windows 2k
platform, I run my program compiled by Compaq Visual Fortran 6.6; in
Sun Solaris 8 platform, I run my program compiled by Sun Fortran 95
compiler. The results caculated by Compaq 6.6 and Sun Fortran 95 are
the same, but the output by PGI compiler is different. I try to use
GNU f77 and IBM ifc to compile my problem. However, neither of them
works. So, I suspect the reliability of PGI compiler and the fortran
compiler under Linux platform. Is there any suggestion to fix this
problem? Thanks in advance!
