This work shows how a Hybrid MPI/OpenMP implementation can improve the performance
of the Ocean-Land-Atmosphere Model (OLAM) on a multi-core cluster environment, which is …

Reliable distributed data storage systems have to employ redundancy codes to tolerate the
loss of storages. Many appropriate codes and algorithms can be found in the literature, but …

This paper presents the use of trace-based performance visualization of a large scale
atmospheric model, the Ocean-Land-Atmosphere Model (OLAM). The trace was obtained …

This thesis focuses on I/O scheduling as a tool to improve I/O performance on parallel file
systemsby alleviating interference effects. It is usual for High Performance Computing (HPC) …

Weather forecasts for long periods of time has emerged as increasingly important. The
global concern with the consequences of climate changes has stimulated researches to …

Atmospheric models usually demand high processing power and generate large amounts of
data. As the degree of parallelism grows, the I/O operations may become the major …

For a long time, data I/O and storage has been a source of performance contention for HPC
applications: the limited bandwidth to transfer data in and out of processing nodes and …

Nowadays has been observed a large increase in the volume of images generated by
medical devices. The manipulation of medical images has one known as DICOM standard …

The DIODE-A project associate the INRIA project-teams Mescal and Moais, as well as the
