compiler and linker options

What does the option


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

Also, does


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.


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.
