Parallelization Options by Language

Option	Meaning
-mt	Indicates compilation and linking for multithreaded code.
-xautopar	Turns on automatic parallelization for multiple processors.
-xcheck	Enables a runtime check for stack overflow.
-xdepend	Analyzes loops for inter-iteration data dependencies and performs loop restructuring.
-xexplicitpar	Parallelizes the loops that are specified.
-xloopinfo	Shows which loops are parallelized and which are not.
-xopenmp	Enable explicit parallelization with OpenMP directives.
-xparallel	Parallelizes loops both automatically (by the compiler) and explicitly (as specified by the programmer).
-xreduction	Analyzes loops for reduction in automatic parallelization.
-xsafe	Allows the compiler to assume that no memory protection violations occur.
-xthreadvar	Works in conjunction with the __thread declaration specifier to take advantage of the compiler's thread-local storage facility.
-xvpara	Show parallelization warning messages.
-Zll	Creates the program database for lock_lint, but does not generate executable code.
