Practical parallel remote method invocation for the Babel compiler

Parallel components are types of software components that contain Single Program Multiple Data (SPMD) parallel code and are used and defined by the Common Component Architecture (CCA) component model. Parallel Remote Method Invocation (PRMI) defines a communication paradigm between two parallel components of this kind. Within the CCA community, we define PRMI to include two parts: collective invocations and data redistribution. In this paper, wedevise a way to build PRMI onto the Babel compiler, which is a central supporting technology of CCA. We perform this integration cleanly, by preserving Babel's design principles and allowing user choice in the wire protocol and parallel communication library. In addition to this, we define a novel set of synchronization options for PRMI that allow trading off synchronization for better performance while notendangering the accuracy of the result.
