Partitioned Global Address Space (PGAS) library for distributed arrays

The Global Arrays GA toolkit provides a shared memory style programming environment in the context of distributed array data structures called “global arrays”. From the user perspective, a global array can be used as if it was stored in shared memory. All details of the data distribution, addressing, and data access are encapsulated in the global array objects. Information about the actual data distribution and locality can be easily obtained and taken advantage of whenever data locality is important. The primary target architectures for which GA was developed are massively-parallel distributed-memory and scalable shared-memory systems.
