HPC4EAS (High Performance Computing for Efficient Applications and Simulation Research Group)

Our main investigation objectives will address the research and technology challenges of meeting the requirements of next generation Cloud Computing architectures for the efficient execution of compute and data-intensive High Performance Computing services. We have defined four strategic research objectives that correspond with the four architectural layers of HPC for Efficient Applications & Simulation (hpc4eas): Performance and Efficiency in the use of HPC resources, User Availability of HPC Resources, Design and Optimization of HPC Systems for Specific "Workloads" (application-specific domains) and Social Projection Applications. The results of the these research lines will offer a considerable improvement in resource utilization, energy efficiency and cost of current scientific and business infrastructures; will support new provisioning models for computing centres to offer on-demand capacity in order to scale user’s environment and accommodate ongoing growth, and will establish the principals of porting HPC applications to clusters and Clouds.

Predicting robustness against transient faults of MPI based programs / Dias Lima Gramacho, João Artur (Universitat Autònoma de Barcelona. Departament d'Arquitectura de Computadors i Sistemes Operatius) ; Wong, Álvaro (Universitat Autònoma de Barcelona. Departament d'Arquitectura de Computadors i Sistemes Operatius) ; Rexachs del Rosario, Dolores Isabel (Universitat Autònoma de Barcelona.

The evaluation of a program's behaviour in the presence of transient faults is often a very time consuming work. In order to achieve significant data, thousands of executions are required and each execution will have the significant overhead of the fault injection environment. [...]

Executing traditional Message Passing Interface (MPI) applications on multi-core cluster balancing speed and computational efficiency is a difficult task that parallel programmers have to deal with. For this reason, communications on multi-core clusters ought to be handled carefully in order to improve performance metrics such as efficiency, speedup, execution time and scalability. [...]
