Somewhere between a multi-processor coherent system and a cluster? That sounds somewhat like the "tuple spaces" concept (https://en.wikipedia.org/wiki/Tuple_space).

In that software design, applications running on a cluster of servers can "connect to a shared memory space" using a library. The library api provides some reasonably standard data-structures (particularly key/value maps and queues).

In practice, the storage is usually distributed across the nodes belonging to the cluster (ie there is no "central server" with lots of memory). In the case of "the machine", perhap tuple-spaces might be a useful way to access this central memory (which would _really_ be central rather than distributed), to reduce the problems related to coherency?

Thanks for the pointer. We've got a bunch of people in HP labs figuring out how to get data structures to work on this hardware; will pass this along to them.
