Abstract
Utilization of computing power of idle workstations and tolerating failures of computing nodes running parallel message-passing applications is the research area attracting many research groups in Computer Science. A Channel Memory based approach has shown its capabilities to tolerate faults of tasks of parallel applications. The first work utilizing such approach in conjunction with a specially designed checkpointing and recovery protocol has been resulted in MPICH-V architecture. In this paper, we present Channel Memory based Dynamic Environment (CMDE) – a stand-alone distributed program system based on MPICH-V architecture. We also present an approach to tolerate faults of Channel Memories, based on CMDE architecture and on a Limited Replication of Channel Memories algorithm, introduced in this paper.
