The Processing Graph Method (PGM), developed at the Naval Research Laboratory (NRL) in Washington, DC, is an architecture independent method for specifying application software for parallel architectures. The on-going PGM Tool (PGMT) project at NRL will devolop a toolset for rapid, low-cost production of PGM "compilers" for parallel architectures.
A major part of the PGMT effort will be the assignment of processes to processors. This will explore various assignment methods for Dynamic Data Flow (DDF) graphs, where the flow of data between processing nodes is data dependent and thus not predictable at compile time. These assignment methods will be evaluated for there effectiveness in providing high throughput with low memory requirements and low latency.
