High-level Language Optimizations

Option	Description
-openmp	Enables the parallelizer to generate multi-threaded code based on the OpenMP* directives. Enables parallel execution on both uni- and multiprocessor systems.
-openmp_report{0\|1\|2}	Controls the OpenMP* parallelizer's diagnostic levels 0, 1, or 2: 0 - no information 1 - loops, regions, and sections parallelized (default) 2 - same as 1 plus master construct, single construct, etc.
-unroll[n]	Set maximum number (n) of times to unroll loops. Omit n to use default heuristics. Use n =0 to disable loop unrolling. For Itanium®-based applications, -unroll[0] used only for compatibility.

Description

-openmp

Enables the parallelizer to generate multi-threaded code based on the OpenMP* directives.
Enables parallel execution on both uni- and multiprocessor systems.

-openmp_report{0|1|2}

Controls the OpenMP* parallelizer's diagnostic levels 0, 1, or 2:

0 - no information
1 - loops, regions, and sections parallelized (default)
2 - same as 1 plus master construct, single construct, etc.

-unroll[n]

Set maximum number (n) of times to unroll loops. Omit n to use default heuristics. Use n =0 to disable loop unrolling. For Itanium®-based applications, -unroll[0] used only for compatibility.
