Data diffusion machine

Data diffusion machine is a historical virtual shared memory architecture where data is free to migrate through the machine.

Shared memory machines are convenient for programming but do not scale beyond tens of processors. The Data Diffusion Machine (DDM) overcomes this problem by providing a virtual memory abstraction on top of a distributed memory machine. A DDM appears to the user as a conventional shared memory machine but is implemented using a distributed memory architecture.
