Efficient use of parallel libraries on heterogeneous Networks of Workstations

A. Clematis, G. Dodero, V. Gianuzzi
2000 Journal of systems architecture  
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  ...  PVM is also upwards compatible with MPI, the standard for parallel applications, which as present has been less used on heterogeneous networks.  ...
