We establish the following, quite unexpected, result: replication of data for the computational
private information retrieval problem is not necessary. More specifically, based on the …

Data-intensive e-science collaborations often require the transfer of large files with
predictable performance. To meet this need, we design novel admission control (AC) and …

The provision of Quality of Service (QoS) in Grid environments is still an open issue that
needs attention from the research community. One way of contributing to the provision of …

Grid economy provides a mechanism or incentive for resource owners to be part of the Grid,
and encourages users to utilize resources optimally and effectively. Advance reservation …

The advancement of optical networking technologies has enabled e-science applications
that often require transport of large volumes of scientific data. In support of such data …

Recently, the advance reservation functionality gained high importance in grids due to
increasing popularity of modern applications that require interactive tasks, co-allocation of …

In Grids, users may require assurance for completing their jobs on shared resources. Such
guarantees can only be provided by reserving resources in advance. However, if many …

In this paper, we propose a new method for multi-user, multicriteria job scheduling in Grid
environments with QoS guarantees concerning time and cost. The main goal of our method …

In Grid systems, users may require assurance for completing their jobs on shared resources.
Such guarantees can only be provided by reserving resources in advance. In this paper, we …

In most Grid systems, submitted jobs are initially placed into a queue if there are no
available compute nodes. Therefore, there is no guarantee as to when these jobs will be …
