Abstract
An automated method of optimizing execution of a program in a parallel processing environment is disclosed. The program has a plurality of threads and is executable in parallel and serial hardware. The method includes receiving the program at an optimizer and compiling the program to execute in parallel hardware. The execution of the program is observed by the optimizer to identify a subset of memory operations that execute more efficiently on serial hardware than parallel hardware. A subset of memory operations that execute more efficiently on parallel hardware than serial hardware are identified. The program is recompiled so that threads that include memory operations that execute more efficiently on serial hardware than parallel hardware are compiled for serial hardware, and threads that include memory operations that execute more efficiently on parallel hardware than serial hardware are compiled for parallel hardware. Subsequent execution of the program occurs using the recompiled program.
