What does the option

march=core2

mean in a compilation and linking stage for an Intel Processor?

Also, does

DSSE_SUPPORT

mean sse3 instruction support or something else?

Any help appreciated. Thanks in advance.

Hi James,

This isn't a PGI flag. Please check your compiler's documentation for the definition.

Quote:
DSSE_SUPPORT
Define flag (-D) are preprocessor macro settings that enable or disable conditional compilation within a program. The exact meaning of the macro will be within the source code.
