In order to improve the dynamic and scalability of grid, the paper adopts the way fusing P2P and Grid organically, which resolves the issue that the node can join randomly and the resource-sharing can be dynamic in gird. This paper builds a resource architecture model based on P2PGrid and proposes a resource discovery algorithm fusing DHT and ant colony algorithm. This algorithm can accurately and...
Grid is essential for data-intensive application which involves great data transfer among different storage systems. One fundamental service that could be applied to any grid for reliable, high performance data transmission is discussed. Based upon standard FTP protocol, Grid FTP could be extended to the third-party control data transfer, striped data transfer and parallel data transfer. So a Grid...
In this paper, we present a multi-constraint evolutionary algorithm based scheduler for fuzzy grid job scheduling. A chaotic genetic algorithm (CGA) is proposed to schedule jobs with uncertain operation time and flexible deadline on grid. The uncertainty is modeled by fuzzy set based execution time (FSET) model. Chaos is incorporated into standard genetic algorithm by logistic function, a simple equation...
