Characterizing the I/O behavior of scientific applications on the Cray XT

Content Provider ACM Digital Library
Author Roth, Philip C.
Abstract Scientific applications use input/output (I/O) for obtaining initial conditions and execution parameters, as a persistent way of saving program output, and for safeguarding against system unreliability. Although system sizes are expected to continue increasing, I/O performance is not expected to keep pace with system computation and communication performance. Understanding application I/O demands and system I/O capabilities is the first step toward bridging this gap between them. In this paper, we present our approach for characterizing the I/O demands of applications on the Cray XT. We also present preliminary case studies showing the use of our I/O characterization infrastructure with climate studies and combustion simulation programs.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
