2.1 Machine Model

CONVERSE treats the parallel machine as a collection of nodes, where each node is comprised of a number of processors that share memory In some cases, the number of processors per node may be exactly one (e.g. Distributed memory multicomputers such as IBM SP.) In addition, each of the processors may have multiple threads running on them which share code and data but have different stacks. Functions and macros are provided for handling shared memory across processors and querying node information. These are discussed in section 2.13
