High performance computing (HPC) applications have a high requirement on storage speed
and capacity. Non-volatile memory is a promising technology to replace traditional storage …

This paper presents an initiative data prefetching scheme on the storage servers in
distributed file systems for cloud computing. In this prefetching technique, the client …

On large-scale clusters, tens to hundreds of applications can simultaneously access a
parallel file system, leading to contention and in its wake to degraded application …

This paper presents an adaptive replica synchronization mechanism among storage servers
(SSs) without the interference from the metadata server (MDS) in a distributed file system …

AbFS is a distributed file system that makes it possible to efficiently share the inexpensive
devices attached to the commodity computers of a cluster. The implementation of AbFS …

This paper presents an effective method of metadata rebalance in exascale distributed file
systems. Exponential data growth has led to the need for an adaptive and robust distributed …

Large-scale scientific and business applications require data processing of ever-increasing
amounts of data, fueling a demand for scalable parallel file systems comprising hundreds to …

With MPI-IO we see various alternatives for programming file I/O. The overall program
performance depends on many different factors. A new trace analysis environment provides …

This paper presents a proactive data prefetching mechanism on storage servers for
distributed file systems to achieve better input/output (I/O) performance. This mechanism …

In this paper we present a study of I/O access patterns of scientific and general applications
on a parallel file system. Understanding I/O access patterns is an essential condition to …
