Heterogeneous distributed systems are widely deployed for executing computationally
intensive parallel applications with diverse computing needs. Such environments require …

Independence of special elements, transparency and scalability are very significant features
required from the fault tolerance schemes for modern clusters of computers. In order to …

Mapping applications onto heterogeneous platforms is a difficult challenge, even for simple
application patterns such as pipeline graphs. The problem is even more complex when …

A long-term trend in high performance computing is the increasing number of nodes in
parallel computing platforms, which entails a higher failure probability. Hence, fault …

La tolerancia a fallos se ha convertido en un requerimiento importante para los ingenieros
informáticos y los desarrolladores de software, debido a que la ocurrencia de fallos …

This position paper advocates the need for scheduling. Even if resources at our disposal
would become abundant and cheap, not to say unlimited and free (a~ perspective that is not …

The main objective of this chapter is to show the need for algorithmic and scheduling
techniques. Even if resources at our disposal would become abundant and cheap, not to say …

Clusters with thousand of nodes are a reality and the current trend indicates that they are
becoming larger. Such large clusters are subject to a relatively high fault frequency so a fault …

State-of-the-art dense linear algebra software, such as the LAPACK and ScaLAPACK
libraries, suffer performance losses on multicore processors due to their inability to fully …

Tras la recuperación de un fallo, las aplicaciones pierden prestaciones debido, en gran
parte, a que el número planificado de nodos ha disminuido y de la pérdida que provoca la …
