The paper is motivated by eciency considerations about porting mathematical software from Massively Parallel Processors (MPPs) to Networks of Workstations (NOWs). Heterogeneity of the network is the major obstacle to ef-®cient porting: it can be overcome with a specialized system, Programming envIronment for Network of COmputers (PINCO), for monitoring available computational power at dierent nodes, both statically and dynamically. The structure and functionalities of PINCO are outlined, and a
