....into two threads, which handle control messages and computation respectively, to ensure responsiveness to control messages. This doubling of the number of threads may be too expensive, depending on the system being used. An alternative is available for message passing systems such as PVM 3. 4 [11], where we can interrupt the computation to deal with each control message. Another common structure is a devoted send or receive, that is, a send to or receive from a single process, executed without other choices. While non deterministic choice is a powerful construct, it is not always needed. ....

.... lower level message passing mechanisms, dynamic domain decomposition over virtual machine resources, distributed I O, checkpointing, fault tolerance, adaptive mesh refinement, and computational steering insulate model code from changes in the underlying computational and network hardware [13, 14, 27, 31, 32, 36, 37]. A current example directly applicable to atmospheric codes is the Runtime System Library (RSL) 31, 32] In addition to providing high level communication constructs for parallel atmospheric models, RSL provides dynamic decomposition and automatic state data remapping capabilities. The utility ....
