%T A Model for Concurrency Using Single\-Writer Single\-Assignment Variables %A Matthew Huntbach %E Peter H. Welch, Adam T. Sampson, Jan Bækgaard Pedersen, Jon Kerridge, Jan F. Broenink, Frederick R. M. Barnes %B Communicating Process Architectures 2011 %X This is a description of a model for concurrent computation based on single\-writer single\-assignment variables. The description is primarily graphical, resembling the interaction nets formalism. The model embodies rules in a process which may require two or more communications from other processes to respond. However, these are managed by a partial evaluation response on receiving a single communication.
