Current solutions for hybrid grid/cloud computing have been developed to hide from heterogeneity, dynam-icity, and distributed nature of resources. These solutions are, however, insufficient to support distributedapplications with non-trivial communication patterns among processes or that are structured so as to reflectthe organization of...

Distributed computing environments have evolved from in-house clusters to Grids and now Cloud platforms. We, as others, provide HPC benchmarks results over Amazon EC2 that show a lower performance of Cloud resources compared to private resources. So, it is not yet clear how much of impact Clouds will have in high performance computing (HPC)....

Since the appearance of distributed computing technology, there has been a significant effort in designing and building the infrastructure needed to tackle the challenges raised by complex scientific applications that require massive computational resources. This increases the awareness to harness the power and flexibility of Clouds that have...
