Debugging OpenMP Code

Darryl Gove, October 10, 2007

The compiler flag -xopenmp enables the recognition of OpenMP directives. As a side effect it also raises the optimization level to -xO3. If you're trying to debug the code, then you'll not want the optimisation level raised then you can use the option -xopenmp=noopt which enables the recognition of OpenMP directives but does not increase the optimisation level.
