Previous studies have reported that common dense linear algebra operations do not
achieve speed up by using multiple geographical sites of a computational grid. Because …

The aim of the QosCosGrid project is to bring supercomputer-like performance and structure
to cross-cluster computations. To support parallel complex systems simulations, QosCosGrid …

Porting on grids complex MPI applications involving collective communications requires
significant program modification, usually dedicated to a single grid structure. The difficulty …

In this paper, we propose a fine-grained coupling metrics suite for aspect-oriented (AO)
systems, to measure software changes during system evolution. We also present a …

Complex systems modeling and simulation approaches are being adopted in a growing
number of sectors, including finance, economics, biology, astronomy, and many more …

This paper presents the design and implementation of BSP++, a C++ parallel programming
library based on the Bulk Synchronous Parallelism model to perform high performance …

The concept of topology-aware grid applications is derived from parallelized computational
models of complex systems that are executed on heterogeneous resources, either because …

Computational grids present promising computational and storage capacities. They can be
made by punctual aggregation of smaller resources (ie, clusters) to obtain a large-scale …

Nowadays, high performance computing is being improved thanks to different platforms like
clusters, grids, and volunteer computing environments. Volunteer computing is a type of …

This research investigates the potential of the Web services architecture to act as a platform
for the execution of MPI-style applications. The work in this thesis is based upon extending …
