Summary:A status report is provided on the architecture and programming of
a family of concurrent computers that are organized as ensembles of
small programmable computers called nodes, connected by a
message-passing network, each with its own private memory. The
architecture of the multicomputer is described and contrasted with that
of the shared-memory multiprocessor, and the concept of grain size
(which depends on the size of the individual memories) is explained.
Medium-grain and fine-grain multicomputers, with nodes containing
megabytes and tens of kilobytes of memory, respectively, are examined,
and their programming is discussed
