New propositions to improve the efficiency and scalability of DSM systems
Lionel Brunie, Laurent Lefèvre · 2002
This paper describes the DOSMOS parallel programming environment. Based on a DSM layer, this system has been specially designed to ensure scalability and efficiency. Several novel features are introduced as the grouping of processes, the possibility of mixing message-passing (PVM) code and DSM code, the definition of optimized weak consistency protocols, the integration of monitoring facilities. First experiments on networks of workstations show the effectiveness of these features.
