With the explosive growth of genomic information, the searching of sequence databases has
emerged as one of the most computation and data-intensive scientific applications. Our …

As the number of nodes in cluster systems continues to grow, leveraging scalable algorithms
in all aspects of such systems becomes key to maintaining performance. While scalable …

This paper presents the integration of two collective I/O techniques into the Clusterfile
parallel file system: disk-directed I/O and two-phase I/O. We show that global cooperative …

This paper presents the design and implementation of a new file system independent
collective I/O optimization based on file views: view-based collective I/O. View-based …

It is often the case that MPI‐IO performs poorly in a Lustre file system environment, although
the reasons for such performance have heretofore not been well understood. We …

It is widely known that MPI-IO performs poorly in a Lustre file system environment, although
the reasons for such performance are currently not well understood. The research presented …

Lustre is becoming an increasingly important file system for large-scale computing clusters.
The problem is that many data-intensive applications use MPI-IO for their I/O requirements …

Lustre is becoming an increasingly important file system for large-scale computing clusters.
The problem, however, is that many data-intensive applications use MPI-IO for their I/O …

In this paper we present the novel design, implementation, and evaluation of an ad-hoc
parallel I/O system (AHPIOS). AHPIOS is the first scalable parallel I/O system completely …

This paper presents the design and implementation of a portable ad-hoc parallel I/O system
(AHPIOS). AHPIOS virtualizes on-demand available distributed storage resources and …
