Performance prediction across platforms is increasingly important as developers can choose
from a wide range of execution platforms. The main challenge remains to perform accurate …

Modern High-Performance Computing (HPC) systems are adding extra layers to the memory
and storage hierarchy named deep memory and storage hierarchy (DMSH), to increase I/O …

There is growing concern that I/O systems will be hard pressed to satisfy the requirements of
future leadership-class machines. Even current machines are found to be I/O bound for …

Collective I/O, such as that provided in MPI-IO, enables process collaboration among a
group of processes for greater I/O parallelism. Its implementation involves file domain …

Current leadership-class machines suffer from a significant imbalance between their
computational power and their I/O bandwidth. I/O forwarding is a paradigm that attempts to …

We have developed a threaded parallel data streaming approach using Globus to transfer
multi-terabyte simulation data from a remote supercomputer to the scientistýs home …

Parallel file systems (PFS) are widely-used in modern computing systems to mask the ever-
increasing performance gap between computing and data access. PFSs favor large …

Range lock enables concurrent accesses to disjoint parts of a shared storage. However,
existing range lock managers rely on centralized CPU resources to process lock requests …

Abstract Modern High-Performance Computing (HPC) systems are adding extra layers to the
memory and storage hierarchy, named deep memory and storage hierarchy (DMSH), to …

Client-side file caching has long been recognized as a file system enhancement to reduce
the amount of data transfer between application processes and I/O servers. However …
