- Deploying applications in Multi-SAN SMP clustersPublication . Alves, Albano; Pina, António; Rufino, José; Exposto, JoséThe effective exploitation of multi-SAN SMP clusters and the use of generic clusters to support complex information systems require new approaches. On the one hand, multi-SAN SMP clusters introduce another level of parallelism which is not addressed by conventional programming models that assume a homogeneous cluster. On the other hand, traditional parallel programming environments are mainly used to run scientific computations, using all available resources, and therefore applications made of multiple components, sharing cluster resources or being restricted to a particular cluster partition, are not supported. We present an approach to integrate the representation of physical resources, the modelling of applications and the mapping of application into physical resources. The abstractions we propose allow to combine shared memory, message passing and global memory paradigms.
- Mapping application-level components into hierarchical systems resourcesPublication . Alves, Albano; Pina, António; Rufino, José; Exposto, JoséThe appropriate organization of application components and their right mapping into physical resources is fundamental to fully exploit cutting edge technologies especially when hierarchical architectures are used. We present a new approach to combine application modelling with resource management. The proposed programming model allows the mixing of message-passing and global memory facilities and integrates them with the high-level abstractions provided for specifying and organizing application components and resources. The methodologies and tools we had designed pave the way to build complex systems through the use of cooperative applications, executed simultaneously, involving multiple users, thus extending the MPMD model.
- Deploying applications in multi-SAN SMP Clusters (extended version)Publication . Alves, Albano; Pina, António; Rufino, José; Exposto, JoséThe effective exploitation of multi-SAN SMP clusters and the use of generic clusters to support complex information systems require new approaches; multi-SAN SMP clusters introduce new levels of parallelism and traditional environments are mainly used to run scientific computations. In this paper we present a novel approach to the exploitation of clusters that allows integrating in a unique metaphor: the representation of physical resources, the modelling of applications and the mapping of application into physical resources. The proposed abstractions favoured the development of an API that allows combining and benefiting from the shared memory, message passing and global memory paradigms.
