Koha: un software gestionale open source per le biblioteche
No full textKoha is an open-source Integrated Library System (ILS) developed in New Zealand and deployed for the first time in January of 2000 for Horowhenua Library Trust. Koha is a full-fledged software with basic and advanced features. It fits the needs of libraries of any size for its easiness and versatility. In particular, Koha is suitable to all institutions who want to automate their libraries using a system that allows a complete control over data and software itself.Koha è un software gestionale di biblioteca open source sviluppato in Nuova Zelanda e messo in linea per la prima volta nel gennaio 2000 per il Horowhenua Library Trust. Completo di tutti i principali moduli per la gestione di una biblioteca e con funzionalità sia di base che avanzate, Koha si adatta alle esigenze di realtà bibliotecarie di ogni dimensione, grazie alla sua estrema facilità di utilizzo e versatilità. In particolare, esso è rivolto a tutti gli enti che, per esigenze diverse, vogliano automatizzare le proprie biblioteche utilizzando un software che permetta un controllo completo sia sui dati che sul software stesso
Almanacco SBN. News sui servizi CILEA per i Poli SBN: luglio-settembre 2008
No full textIn the quarter just ended, a lot of activities were carried out by CILEA team providing support to SBN poles. In particular, for the Polo USM, that is moving to Sebina OL, CILEA has made the first and important activity essential to the success of the process. Other important activities were carried out for the pole Unix client / server (two UNIMARC imports, both completed successfully) and the pole LO2 (customization of the OPAC for the Library of the Regional Council of Lombardia).Nel trimestre appena trascorso, diverse attività sono state svolte dai team CILEA che forniscono servizi ai poli SBN. In particolare, per il Polo USM (in procinto di passare a Sebina OL) il CILEA ha effettuato le prime operazioni indispensabili per il buon esito del passaggio. Altre attività importanti sono state svolte per i poli Unix client/server (due importazioni UNIMARC, entrambe conclusesi con successo) e per il polo LO2 (la personalizzazione dell’OPAC per la biblioteca del Consiglio regionale della Lombardia)
IPDPS 2009: 23rd IEEE International Parallel & Distributed Processing Symposium
No full textIPDPS is an important international event for engineers and scientists to present their latest research findings in the fields of parallel processing and distributed computing. The themes of IPDPS 2009 were tied together by the great interest of the scientific community for the GPU computing. This kind of technology seems very promising because GPUs are intrinsically and massively parallel with a consequent tremendous computing power if compared to a modern single CPU.IPDPS costituisce un importante evento internazionale dedicato alla divulgazione e promozione dei molteplici aspetti del calcolo e dei processi paralleli e distribuiti. I temi trattati nell’edizione di Roma 2009, erano accomunati dal notevole interesse della comunità scientifica verso il calcolo ad alte prestazioni eseguito sulle GPU, ovvero le Graphical Processing Unit, di cui sono costituite le schede grafiche. Questo tipo di tecnologia sembra essere molto promettente, poiché le GPU sono intrinsecamente e massicciamente parallele e pertanto in grado di fornire singolarmente la potenza di calcolo di svariate CPU
Il Conferencing Service Center del CASPUR: un integratore di servizi per la comunicazione avanzata
No full textIn the past years, several relevant projects in education and communication environmenthave contributed to develop and deploy modern videoconference infrastructures.In this framework CASPUR is playing a significant role, promoting and diffusing videoconferencetechnologies among its scientific partners and public administration. ConferencingService Center (CSC) is an innovative solution for integrating communicationand collaboration services, which promotes audio media as the main communicationchannel. A CSC user gets benefits from audio and data communications using a virtualroom for his meetings, eliminating or lowering barriers of distance and cost of travel.In this way, CSC helps public and private organizations to improve efficiency of internalcommunication and to reduce costs.The CSC web portal service is accessible at http://csc.caspur.it, seven days a weekand 24 hours a day; through this portal, conferencing services can be planned, managedand controlled. It encompasses the following features:• Accounts management in organizational hierarchy• Services booking and scheduling• On line service management• Activity analysis and reportsAs far services are concerned, CSC comprises the following ones:• Audioconferencing: accessing a virtual room using a telephone for voice and a pcor mobile device for data• VideoConferencing: IP/ISDN based virtual rooms for audio and video conference• Webconferencing: a java application built to share data in combination with oneof the two services above• Webstreaming: a customizable live or on demand video broadcastFurther any technological consideration, teleconferencing and related travels reductioncontributes to lower CO2 production.Ing.

L'acquisizione di sistemi HPC: un caso ed alcune note generali
No full textAt the end of 2008, CASPUR has released to its users a new HPC system. The new system,built-up by ClusterVision, has 258 nodes with two quad-core AMD Opteron processors,for a total of 2.064 cores. Nodes are linked through a broad band and low latencyInfiniband switch and have a total of 4.5Tbyte of dynamic memory. The system delivers17.3 TFlops (Rpeak) and 13.6 TFlops (Rmax). Performances and total core-hours peryear have grown 15 and 12 times respectively whilst cost/GFlops has declined to 1/40of the previous one. According to CASPUR, the process adopted to acquire the systemhas been a best practice, with respect of technology and economics results, suitablefor being used in future procurements. The article intends to illustrate such process, underliningmain considerations and motivations in terms of technology, innovation, userneeds adopted to define kind and size of the system as well as the parameters usedto perform the choice. Some more is reported about world-wide HPC innovation scenario,stressing differences between HPC procurement in Europe and in the USA. Eventually,a couple of draft proposals to improve the effectiveness of overall HPCinvestments in Italy
