Abstract
The present disclosure is directed to a method for providing an OpenMP reduction implementation. The method may comprise creating an aggregate of at least one reduction variable in a parallel region or a work-sharing construct; defining a pointer variable, the pointer variable pointing to a dynamic array of the aggregate; creating an initialization routine, an outlined routine and a reduction accumulation routine; replacing the parallel region or the work-sharing construct with a runtime routine, the runtime routine taking a plurality of arguments including an address of the initialization routine, an address of the outlined routine, an address of the reduction accumulation routine, an address of the pointer variable, and a size of the aggregate; and executing the runtime routine when the at least one reduction variable is in the parallel region or the work-sharing construct.
