Abstract
A software-implemented method for dynamically and statically privatizing global storage objects in parallel computer programs written in various programming languages. Privatization is accomplished via transformation of these parallel computer programs under the control of a general purpose computer. The privatization method is system-independent and is portable across various computer architectures and platforms since privatization is accomplished via program transformation; thus, the method does not depend on the features of a particular hardware architecture or configuration, operating system, compiler, linker, or thread environment. The inputs to the method are a parallel computer program, comprising parallel regions of execution and global storage objects, and a privatization specification describing the global storage objects to be privatized and the particular parallel regions, and manner, in which each of these objects is to be privatized. The privatization method itself translates the input parallel computer program into a second parallel computer program, according to the privatization specification, such that the second parallel computer program, when executed, accesses …
