In this paper we propose to enhance concurrency of compu- tation and communication by means of a coordination model we develop on the base of orthogonal parallel programming abstractions called forc- ing expressions. It is shown that besides efficient synchronization forcing expressions can facilitate formal development of dedicated schemes of efficient data exchanges in multilevel memory environment yielding sys- tematic reduction of slow memory accesses. The coordination program- ming facilities are illustrated by a case study to enhance data parallel paradigm of computation.
