ifort on Xeon

[swang]

I am compiling a Fortran program. The make file I used is like:

FCFLAGS = -I(LIBINCLUDE) -O2 -tp p6 -pc 32 convert big_endian
LDIOTUIBS = -O2 -tp p6 -pc 32 -convert big_endian


The above is for a IA32 machine. What should I change so that the same make file can be used on a Xeon(EMT64) machine.

Thank you for your help.

If you are switching to the 64-bit ifort for EM64T, the -tp option would be meaningless, and the -pc32 option would be unlikely to be useful. If you are having specific difficulties, please describe them.

Dear Tim:

Thank you for your help.

I compiled with the original flag. Howver, when I run the execution file, I got bus errors. I don't know whether this is caused by the compiler or the fortran code.

If -tp is meaningless, what option should I use for Xeon?
