Conoscere per innovare: formazione per biblioteche e bibliotecari nell'esperienza CILEA
Get PDFSince 1975, CILEA offers innovative services to its customers - especially for universities and even for libraries.
Starting from 2009 there are two novelties their make different the usual training offer: a) a wider and variegated activities annual calendar; b) the decision to supply courses in the new office of CILEA in Rome, with a room equipped for training.Da ormai oltre un trentennio CILEA fornisce ai suoi utenti servizi innovativi, anche nel campo delle biblioteche, in particolare per le Università. A partire dal 2009, tuttavia, due novità hanno reso significativamente diversa rispetto agli anni precedenti l’offerta formativa di CILEA: a) la strutturazione di un portfolio formativo ampio e variegato, con la predisposizione di un calendario annuale delle attività; b) la decisione di erogare corsi anche nella nuova sede romana del Consorzio, attiva proprio dai primi mesi di quest’anno e dotata di una sala attrezzata per la formazione
Corsi CILEA on-line di programmazione Fortran
Get PDFThe High performance Computing team together with the E-learning Management and Assistance team are realising on-line lessons about programming and efficiently using the high performance computing platforms. The introduction to Fortran programming lessons are a reality already and several students have already joined them. New in-depth modules are going to be offered soon, so that participants will have the opportunity of learning the most modern and efficient Fortran programming techniques.Il gruppo di Calcolo ad Alte Prestazioni e quello di Assistenza alla Formazione a Distanza del CILEA stanno realizzando corsi di formazione on-line sulla programmazione e l’utilizzo delle piattaforme di calcolo intensivo. Il corso di introduzione al Fortran è già una realtà sperimentata da diversi studenti e presto verranno offerti moduli di approfondimento alla programmazione in Fortran che permetteranno ai sottoscrittori di impadronirsi delle tecniche di programmazione più moderne in questo linguaggio, così importante per generare codici tecnico-scientifici efficienti e affidabili
Progetto emodinamica computazionale @CILEA
Get PDFIn this article the use of computational models for haemodynamics problems is introduced highlighting the scien¬tific network concerning this topic in which the High Performance Computing group of CILEA is involved.In questo articolo viene introdotta la modellazione al calcolatore di problemi di emodinamica al fine di illustrare le potenzialità offerte dall’ampio circuito di collaborazioni scientifiche su questo tema in cui la Sezione Calcolo ad Alte Prestazioni e Applica¬zioni Scientifiche e Ingegneristiche del CILEA è coinvolto

Il modello di tasking in OpenMP
No full textThe widespread adoption of multicore processors in all kind of computing devices is springing interest for parallel computing, which is the only approach to achieve the promised performance boosts. Parallel computing is not easy, and the resulting complexity, which is usually tolerated in the computational science field, must be strictly controlled in commercial software life cycles. OpenMP is a widely supported industrial standard for parallel computing on multiprocessors systems. Its basic principles, simplicity and incremental approach, make it an extremely productive paradigm. Up to version 2.5, OpenMP didn’t directly support parallelization of algorithms in which more work is generated dynamically and with irregular patterns as data are processed. These algorithms are of growing relevance in the scientific realm, and are widespread in most commercial software. OpenMP 3.0 introduced a new tasking model, that allows work to be dynamically generated and assigned to idle processors. CASPUR was a very active contributor to the new model development
Il progetto BISMUTH e la partnership con il CASPUR
No full textMultiferroics (for example materials where ferroelectricity and magnetism coexist) arepresently drawing enormous interests, due to their technologically-relevant multifunctionalcharacter and to the astoundingly rich playground for fundamental condensedmatterphysics they constitute. Our project, named BISMUTH and financed as a StartingGrant by the European Research Council, is based on a theoretical and computationalstudy of multiferroics. In particular, several concepts on how to break inversion symmetryand achieve sizable ferroelectricity in magnets are put forward; our approach iscorroborated via first-principles calculations (performed at CASPUR) as tools to quantitativelyestimate relevant ferroelectric and magnetic properties as well as to reveal abinitiothe main mechanisms behind the dipolar and magnetic orders. In closer detail,we focus on the interplay between ferroelectricity and electronic degrees of freedomin magnets, i.e. on those cases where spin- or orbital- or charge-ordering can be thedriving force for a spontaneous polarization to develop. Antiferromagnetism is consideredas a primary mechanism for lifting inversion symmetry; however, the effects ofcharge disproportionation and orbital ordering are also being studied by examining awide class of materials, including ortho-manganites with E-type spin-arrangement,non-E-type antiferromagnets, nickelates, etc. The link between electronic degrees offreedom and ferroelectricity in collinear magnets is an almost totally unexplored fieldby ab-initio methods; indeed, its clear understanding and optimization would lead toa scientific breakthrough in the multiferroics area. Technologically, it would pave theway to materials design of magnetic ferroelectrics with properties persisting at hightemperatures and, therefore, to a novel generation of electrically-controlled spintronicdevices
Stare su Google ma non solo: OJS per l'editoria scientifica e accademica periodica
Get PDFScientific journals have been the only broadcasting system for research results for centuries, but today scholarly communication is turning towards more innovative paradigms. Open Access publishing provides authors with a competitive advantage as for visibility, impact, reputation, and positive consequences on carriers and research funding. OJS - Open Journal Systems is a widespread open-source software that allows to go online, to be ranked high by search engines, to manage the editorial workflow reducing costs and enhancing quality.Le riviste scientifiche sono state per secoli l'unico canale di diffusione dei risultati della ricerca, ma la comunicazione scientifica è orientata verso paradigmi innovativi. Pubblicare ad accesso aperto procura agli autori un vantaggio competitivo in termini di visibilità, impatto, reputazione, con conseguenze positive sulla carriera e i finanziamenti. OJS - Open Journal Systems è il diffusissimo software open source che consente di andare online, essere indicizzati efficacemente dai motori di ricerca generalisti e specializzati, organizzare il processo editoriale riducendo i costi e aumentando la qualità
