Dynamic node reconfiguration in a parallel-distributed environment

Dynamic Node Recon guration in a Parallel-Distributed Environment

Idle workstations in a network represent a signi cant computing potential. In particular, their processing power can be used by parallel-distributed programs that treat the network as a loosely-coupled multiprocessor. But the set of machines free to participate in load sharing changes over time as users come and go from their workstations. To make full use of the available resources, parallel-d...

Dynamic reconfiguration of node location in wormhole networks

Several techniques have been developed to increase the performance of parallel computers. Recon®gurable networks can be used as an alternative to increase the performance. Network recon®guration can be carried out in di€erent ways. Our research has focused on distributed memory systems with dynamic recon®guration of node location. Brie ̄y, this technique consists of positioning the processors in...

Uniform Execution Environment for Dynamic Reconfiguration

Modern high-performance embedded systems face many challenges. Systems must function in rapidly changing environments. Power/size constraints limit hardware size, while extreme performance requirements demand algorithmspecific architectures. Hardware architectures must structurally adapt to achieve high performance with changing algorithms. Reconfigurable computing devices offer the promise of ...

A Formalization of Autonomous Dynamic Reconfiguration in Distributed Constraint Satisfaction

Parallel Communication in a Large Distributed Environment

In this paper, we describe the evolution of MultiRPC, a parallel remote procedure call mechanism implemented in Unix. Parallelism is ohtained from the concurrency of processing on servers and from the overlapping of retransmissions and timeouts. Each of the parallel calls retains the semantics and functionality of our standard remote procedure calls. The underlying communication medium need not...
