We propose and analyze threading algorithms for hybrid MPI/OpenMP parallelization of a
molecular-dynamics simulation, which are scalable on large multicore clusters. Two data …

Client-side caching is an effective technique to improve I/O performance in network-based
file systems. However, current block-indexed caching structure suffers from cache efficiency …

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 …

Forecast precisions of climatological models are limited by computing power and time
available for the executions. As more and faster processors are used in the computation, the …

Client-side caching is an effective technique to hide network latency and improve I/O
performance in network-based file systems. Current methods mainly adopt block-indexed …

Numerical models have been used extensively in the last decades to understand and
predict weather phenomena and the climate. In general, models are classified according to …

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 …

Elasticity is considered one of the fundamental properties of cloud computing, and can be
seen as the ability of a system to increase or decrease the computing resources allocated in …

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) …

This work discuss the parallel performance of a global numerical simulation model, Ocean-
Land-Atmosphere Model (OLAM), on a hybrid multicore/GPU cluster environment, under the …
