PGAS (Partitioned Global Address Space) is an abstract programming model, which presents an abstraction of a single shared address space, but the address space is partitioned into regions based on an underlying NUMA (non-uniform memory access) architecture. There are several PGAS langauges, including X10, Fortress, Chapel, and UPC. APGAS (Asynchronous PGAS) is a variant of PGAS that supports asynchronous operations and control flow. X10 is an APGAS langauge.
