Therefore, grid resource selection should take into account the proximity of the computational resources to the needed data in order to reduce the cost of file staging. This fact is specially relevant in the case of adaptive job execution, since job migration requires the transf

Controlling the resource allocation in those networks is nearly impossible using a centralized arbitrator. The network simulation project CATNET will evaluate a decentralized mechanism for resource allocation, which is based o

We present XSQL, a technology that solves the heterogeneity problem but lacks adequate security mechanisms for i
