We present a comprehensive survey on parallel I/O in the high-performance computing
(HPC) context. This is an important field for HPC because of the historic gap between …

The imbalanced I/O load on large parallel file systems affects the parallel I/O performance of
high-performance computing (HPC) applications. One of the main reasons for I/O …

HPC systems are composed of multiple tiers of storage, from the top high performance tier
(high speed SSDs) to the bottom capacitive one (tapes). File placement in such architecture …

In the big data era, data unavailability, either temporary or permanent, becomes a normal
occurrence on a daily basis. Unlike the permanent data failure, which is fixed through a …

The performance gap between processor and storage device has continuously increased
during the past few decades. The gap is further exacerbated recently because applications …

To meet ever increasing capacity and performance requirements of emerging data-intensive
applications, parallel file systems (PFSs) have been employed in large-scale computing …
