It contains large data sets for I/O in scientific applications. The analysis demonstrates that the scalability of the system gets worse as we increase the number of cores per machine, with greater impact on output operations. We also demonstrate poor capacity of the multicore system for providing high aggregate I/O bandwidth and that the scalability is not improved when I/O operations are running trough a parallel file system neither running on local disk. %@mirrorrepository sid.inpe.br/mtc-m19@80/2009/08.21.17.02.53 %T I/O performance evaluation on multicore clusters with atmospheric model environment %@isbn 978-076954276-8 %@secondarytype PRE CI %K Atmosphere models, Atmospheric model, Climate simulation, I/O bandwidth, I/O operations, I/O performance, Large datasets, Multi-core cluster, Multi-core systems, Parallel file system, Scientific applications Engineering controlled terms: Climate models, Computer simulation, File organization, Scalability. %8 27 - 30 Oct. 2010 %@usergroup administrator %@usergroup marciana %@group %@group %@group CPT-CPT-INPE-MCT-BR %@secondarykey INPE--PRE/ %2 sid.inpe.br/mtc-m19/2011/02.18.11.28.32 %@affiliation a Laboratório Nacional de Computação Científica (LNCC), Caixa Postal 25651 - 075, Petrópolis - RJ, Brazil %@affiliation b Instituto de Inforḿ %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation %@affiliation a Laboratório Nacional de Computação Científica (LNCC), Caixa Postal 25651 - 075, Petrópolis - RJ, Brazil %@affiliation b Instituto de Inforḿ %@affiliation atica, Universidade Federal do Rio Grande do sul (UFRGS), Caixa Postal 15.064 - 91.501-970, Porto Alegre - RS, Brazil %P 49-54 %4 sid.inpe.br/mtc-m19/2011/02.18.11.28 %@documentstage not transferred %D 2010 %1 FAPERJ, Cons.
