ARCHIVED: On IU's research systems, should I use a vendor-provided compiler or a third-party compiler instead of the GNU compiler?

While the GNU compiler available on Indiana University's research systems is designed for portability, it does not necessarily optimize your code for a specific vendor system. Vendor-supplied or third-party compilers typically offer options for optimization and may offer superior math accuracy in addition to improved performance. Third-party compilers may also be particularly well suited for porting codes from another vendor platform.
