The development of high level abstractions for programming distributed systems is becoming a crucial effort in computer science. Several frameworks have been proposed, which expose simplified programming abstractions that are useful for a broad class of ...

A grid scheduling algorithm inspired on the simulated annealing meta-heuristic (SA) is presented. Guided by predictions about parallel applications resource usage, the algorithm uses SA to find a near-optimal solution which minimizes the overall ...

The development of grid algorithms is frequently hampered by limited means to describe topologies and lack of support for the invasive composition of legacy components in order to pass data between them. In this paper we present a solution to overcome ...

Numerous studies have shown that Operating System (OS)noise is one of the reasons for significant performance degradation in clustered architectures. Although many studies examine the OS noise for High Performance Computing (HPC),especially in multi-...

Over the last years, the issue of reducing energy consumption in hard real-time embedded systems has received considerable attention from the scientific community, since responsiveness and low energy consumption are often conflicting requirements. In ...

Although grid systems have evolved in such a way that they are largely used both in industry and academy, techniques to test and evaluate them, such as simulation and emulation, have limitations on both their applicability and their reliability. We are ...
