Abstract
A computer implemented method, system and computer program product for accessing threadprivate memory for threadprivate variables in a parallel program during program compilation. A computer implemented method for accessing threadprivate variables in a parallel program during program compilation includes aggregating threadprivate variables in the program, replacing references of the threadprivate variables by indirect references, moving address load operations of the threadprivate variables, and replacing the address load operations of the threadprivate variables by calls to runtime routines to access the threadprivate memory. The invention enables a compiler to minimize the runtime routines call times to access the threadprivate variables, thus improving program performance.
