BSC - Barcelona Supercomputing Center
Early in 2004 the Ministry of Education and Science (Spanish Government), Generalitat de Catalunya (local Catalan Government) and Technical University of Catalonia (UPC) took the initiative of creating a National Supercomputing Center in Barcelona. BSC-CNS (Barcelona Supercomputing Center – Centro Nacional de Supercomputación) is the National Supercomputing Facility in Spain and was officially constituted in April 2005. BSC-CNS manages MareNostrum, one of the most powerful supercomputers in Europe, located at the Torre Girona chapel. The mission of BSC-CNS is to investigate, develop and manage information technology in order to facilitate scientific progress. With this aim, special dedication has been taken to areas such as Computer Sciences, Life Sciences, Earth Sciences and Computational Applications in Science and Engineering.

YOLO: Speeding Up VM and Docker Boot Time by Reducing I/O Operations
(Springer, 2019)
Part of book or chapter of book
Open AccessAlthough this comes as a surprise, the time to boot a Docker-based container can last as long as a virtual machine in high consolidated cloud scenarios. Because this time is critical as boot duration defines how an application ... -
Introducing the Task-Aware Storage I/O (TASIO) Library
(Springer, 2019-08-09)
Part of book or chapter of book
Open AccessTask-based programming models are excellent tools to parallelize and seamlessly load balance an application workload. However, the integration of I/O intensive applications and task-based programming models is lacking. ... -
On the discretization of the ice thickness distribution in the NEMO3.6-LIM3 global ocean–sea ice model
(European Geosciences Union (EGU), 2019-08-27)
Article
Open AccessThe ice thickness distribution (ITD) is one of the core constituents of modern sea ice models. The ITD accounts for the unresolved spatial variability of sea ice thickness within each model grid cell. While there is a ... -
Nasal sprayed particle deposition in a human nasal cavity under different inhalation conditions
(Public Library of Science, 2019-09-06)
Article
Open AccessDeposition of polydisperse particles representing nasal spray application in a human nasal cavity was performed under transient breathing profiles of sniffing, constant flow, and breath hold. The LES turbulence model was ... -
