—The increasing demand for resources of the high performance computing systems has led to new forms of collaboration of distributed systems such as interoperable grid systems tha...
1 The unstructured Peer-to-Peer (P2P) systems usually use a “blind search” method to find the requested data object by propagating a query to a number of peers randomly. In or...
—Data replications is a typical strategy for improving access performance and data availability in Data Grid systems. Current works on data replication in Grid systems focus on t...
We address the problem of making online, parallel query plans fault-tolerant: i.e., provide intra-query fault-tolerance without blocking. We develop an approach that not only achi...
Periodic and aperiodic tasks co-exist in many realtime systems. The periodic tasks typically arise from sensor data or control loops, while the aperiodic tasks generally arise fro...
