It is a matter of consensus that the ability to efficiently use current and future high performance computing systems is crucial for science, however, the reality is that the performance currently achieved by most of the parallel scientific applications is far from desired. [...]

How to use mixed precision in ocean models : Exploring a potential reduction of numerical precision in NEMO 4.0 and ROMS 3.6 / Tintó Prims, Oriol (Universitat Autònoma de Barcelona. Departament d'Arquitectura de Computadors i Sistemes Operatius) ; Acosta, Mario C. (Mario César) (Barcelona Supercomputing Center) ; Moore, Andrew M. (University of California. Ocean Sciences Department (USA)) ; Castrillo, Miguel (Barcelona Supercomputing Center) ; Serradell, Kim (Barcelona Supercomputing Center) ; Cortés Fité, Ana (Universitat Autònoma de Barcelona. Departament d'Arquitectura de Computadors i Sistemes Operatius) ; Doblas-Reyes, Francisco J. (Barcelona Supercomputing Center)
Mixed-precision approaches can provide substantial speed-ups for both computing- and memory-bound codes with little effort. Most scientific codes have overengineered the numerical precision, leading to a situation in which models are using more resources than required without knowing where they are required and where they are not. [...]

NEMO: computational challenges in ocean simulation / Tintó Prims, Oriol ; Cortés Fité, Ana, dir. ; Acosta, Mario C., (Mario César) dir. ; Doblas-Reyes, Francisco Javier, dir. ; Universitat Autònoma de Barcelona. Departament d'Arquitectura de Computadors i Sistemes Operatius
Els oceans juguen un paper molt important modulant la temperatura de la Terra absorbint, emmagatzemant i transportant l'energia que ens arriba del sol. Entendre millor la dinàmica dels oceans pot ajudar a millorar les prediccions meteorològiques i a comprendre millor el clima, qüestions d'especial rellevància per la societat. [...]
The ocean plays a very important role in modulating the temperature of the Earth through absorbing, storing and transporting the energy that arrives from the sun. Better understanding the dynamics of the ocean can help us to better predict the weather and to better comprehend the climate, two topics of special relevance for society. [...]
