  • Aeneas: A tool to enable applications to effectively use non-relational databases 

    Cugnasco, Cesare; Hernández, Roger; Becerra Fontal, Yolanda; Torres Viñals, Jordi; Ayguadé Parra, Eduard (Elsevier, 2013)
    Conference report
    Open Access
    Non-relational databases arise as a solution to solve the scalability problems of relational databases when dealing with big data applications. However, they are highly configurable prone to user decisions that can heavily ...
  • A framework for multidimensional indexes on distributed and highly-available data stores 

    Cugnasco, Cesare; Becerra Fontal, Yolanda (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    No-relational databases are nowadays a common solution when dealing with a huge data set and massive query workload. These systems have been redesigned from scratch in order to achieve scalability and availability at ...
  • BIGNASim: a NoSQL database structure and analysis portal for nucleic acids simulation data 

    Hospital, Adam; Andrio, Pau; Cugnasco, Cesare; Codo, Laia; Becerra Fontal, Yolanda; Dans, Pablo D.; Battistini, Federica; Torres Viñals, Jordi; Goñi, Ramon; Orozco, Modesto; Gelpi, Josep Lluis (2016-01-04)
    Article
    Open Access
    Molecular dynamics simulation (MD) is, just behind genomics, the bioinformatics tool that generates the largest amounts of data, and that is using the largest amount of CPU time in supercomputing centres. MD trajectories ...

  • Exploiting key-value data stores scalability for HPC 

    Cugnasco, Cesare; Becerra Fontal, Yolanda; Torres Viñals, Jordi; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    BigData revolutionised the IT industry. It first interested the OLTP systems. Distributed Hash Tables replaced Traditional SQL databases as they guaranteed low response time on simple read/write requests. The second wave ...
  • A framework for multidimensional indexes on distributed and highly-available data stores 

    Cugnasco, Cesare (Universitat Politècnica de Catalunya, 2019-03-22)
    Doctoral thesis
    Open Access
    Spatial Big Data is considered an essential trend in future scientific and business applications. Indeed, research instruments, medical devices, and social networks generate hundreds of peta bytes of spatial data per year. ...
  • ParaView + Alya + D8tree: Integrating high performance computing and high performance data analytics 

    Artigues, Antoni; Cugnasco, Cesare; Becerra Fontal, Yolanda; Cucchietti, Fernando; Houzeaux, Guillaume; Vázquez, Mariano; Torres Viñals, Jordi; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Elsevier, 2017)
    Article
    Open Access
    Large scale time-dependent particle simulations can generate massive amounts of data, making it so that storing the results is often the slowest phase and the primary time bottleneck of the simulation. Furthermore, analysing ...
