The continuous increase in the data produced by simulations, experiments and edge components in the last few years has forced a shift in the scientific research process, leading to the definition of a fourth paradigm in Science, concerning data-intensive computing. This data deluge, in fact, introduces various challenges related to big data volumes, formats heterogeneity and the speed in the data production and gathering that must be handled to effectively support scientific discovery. To this end, High Performance Computing (HPC) and data analytics are both considered as fundamental and complementary aspects of the scientific process and together contribute to a new paradigm encompassing the efforts from the two fields called High Performance Data Analytics (HPDA). In this context, the Ophidia project provides a HPDA framework which joins the HPC paradigm with scientific data analytics. This contribution presents some aspects regarding the Ophidia HPDA framework, such as the multidimensional storage model, its distributed and hierarchical implementation along with a benchmark of a parallel in-memory time series reduction operator.

Abstract
The continuous increase in the data produced by simulations, experiments and edge components in the last few years has forced a shift in the scientific research process, leading to the definition of a fourth paradigm in Science, concerning data-intensive computing. This data deluge, in fact, introduces various challenges related to big data volumes, formats heterogeneity and the speed in the data production and gathering that must be handled to effectively support scientific discovery. To this end, High Performance Computing (HPC) and data analytics are both considered as fundamental and complementary aspects of the scientific process and together contribute to a new paradigm encompassing the efforts from the two fields called High Performance Data Analytics (HPDA). In this context, the Ophidia project provides a HPDA framework which joins the HPC paradigm with scientific data analytics. This contribution presents some aspects regarding the Ophidia HPDA framework, such as the multidimensional storage model, its distributed and hierarchical implementation along with a benchmark of a parallel in-memory time series reduction operator.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
