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.

Recent Submissions

  • YOLO: Speeding Up VM and Docker Boot Time by Reducing I/O Operations 

    Nguyen, Thuy L.; Nou Castell, Ramon; Lebre, Adrien (Springer, 2019)
    Part of book or chapter of book
    Open Access
    Although 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 

    Roca Nonell, Aleix; Beltran Querol, Vicenç; Mateo Bellido, Sergi (Springer, 2019-08-09)
    Part of book or chapter of book
    Open Access
    Task-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 

    Massonnet, François; Barthélemy, Antoine; Worou, Koffi; Fichefet, Thierry; Vancoppenolle, Martin; Rousset, Clément; Moreno-Chamarro, Eduardo (European Geosciences Union (EGU), 2019-08-27)
    Article
    Open Access
    The 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 

    Calmet, Hadrien; Inthavong, Kiao; Eguzkitza, Beatriz; Lehmkuhl, Oriol; Houzeaux, Guillaume (Public Library of Science, 2019-09-06)
    Article
    Open Access
    Deposition 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 ...
  • Enabling CUDA acceleration within virtual machines using rCUDA 

    Duato, José; Peña, Antonio J.; Silla, Federico; Fernández, Juan C.; Mayo, Rafael; Quintana-Ortí, Enrique S. (IEEE, 2012-02-16)
    Conference lecture
    Open Access
    The hardware and software advances of Graphics Processing Units (GPUs) have favored the development of GPGPU (General-Purpose Computation on GPUs) and its adoption in many scientific, engineering, and industrial areas. ...
  • SmarTmem: Intelligent Management of Transcendent Memory in a Virtualized Server 

    Garrido, Luis A.; Nishtala, Rajiv; Carpenter, Paul (IEEE, 2019-07-29)
    Conference lecture
    Open Access
    Managing memory capacity in virtualized environments is still a challenging problem. Many solutions have been proposed and implemented, including memory ballooning and memory hotplug. But these mechanisms are slow to respond ...
  • Multi-model seasonal forecasts for the wind energy sector 

    Lee, Doo Young; Doblas-Reyes, Francisco J.; Torralba, Verónica; Gonzalez-Reviriego, Nube (Springer, 2019-09)
    Article
    Restricted access - publisher's policy
    An assessment of the forecast quality of 10 m wind speed by deterministic and probabilistic verification measures has been carried out using the original raw and two statistical bias-adjusted forecasts in global coupled ...

    Jordà, Marc; Valero-Lara, Pedro; Peña, Antonio J. (IEEE, 2019-05-24)
    Article
    Open Access
    Convolutional neural networks (CNNs) have recently attracted considerable attention due to their outstanding accuracy in applications, such as image recognition and natural language processing. While one advantage of the ...
  • 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; Acosta, Mario C.; Moore, Andrew M.; Castrillo, Miguel; Serradell, Kim; Cortés, Ana; Doblas-Reyes, Francisco J. (European Geosciences Union (EGU), 2019-07-24)
    Article
    Open Access
    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 ...
