✦ Synopsis

MPOOL is an object-oriented extension to the MPI library, based on three categories of objects, called units, groups and schemes. Units are active objects composed of data (state) and procedures (like traditional passive objects), but with the additional ability to store incoming messages in a queue while they are active and to send messages in parallel to other units; moreover, different units may be active simultaneously. Groups and schemes are passive objects used for the composition of units and the co-ordination of their actions. Groups manage collective communications and synchronization operations such as barriers. Schemes compose units' actions through the use of a set of constructs derived by path expressions.
