A growing disparity between supercomputer computation speeds and I/O rates makes it
increasingly infeasible for applications to save all results for offline analysis. Instead …

The Coupled Model Intercomparison Project (CMIP) is one of the biggest international efforts
aimed at better understanding the past, present, and future of climate changes in a multi …

The growth of computing power on large-scale systems requires commensurate high-
bandwidth I/O systems. Many parallel file systems are designed to provide fast sustainable …

High performance computing (HPC) architectures have been adding new layers of storage,
such as burst buffers, to tolerate latency between memory and disk-based file systems …

Modern HPC systems are collecting large amounts of I/O performance data. The massive
volume and heterogeneity of this data, however, have made timely performance of in-depth …

The growing computing power on leadership HPC systems is often accompanied by ever-
escalating failure rates. Checkpointing is a common defensive mechanism used by scientific …

Earth system models have considerably increased their spatial resolution to solve more
complex problems and achieve more realistic solutions. However, this generates an …

Scientific applications frequently spend a large fraction of their execution time in reading and
writing data on parallel file systems. Identifying these I/O performance bottlenecks and …

Although using ontologies to assist information retrieval and text document processing has
recently attracted more and more attention, existing ontologybased approaches have not …

I/O is often a performance bottleneck in global ocean circulation models with fine spatial
resolution. In this paper, we present an asynchronous parallel I/O framework and …
