A computer-implemented method for determining whether an array within a loop can be privatized for that loop is presented. The method calculates the array sections that require first or last privatization and copies only those sections, reducing the privatization overhead of the known solutions.

Method of partially copying first and last private arrays for parallelized loops based on array data flow

A method, apparatus, and computer program product are provided by the present invention for a programming framework for easy pattern matching and transformation of intermediate language expression trees. With expression matching and transformation framework (EMTF) of the present invention, pattern matchers may be defined and embedded in a C++ program code in a manner that resembles their intermediate representation. EMTF also provides capabilities for unification, unbinding, transformation, intra-pattern referencing, common operators, creation of pattern objects in a storage pool. Recursive sub-expression matching and recursive transformation are also included.
