Input/Output Characteristics of Scalable Parallel Applications

Rapid increases in computing and communication performance are exacerbating the long-standing problem of performance-limited input/output. Indeed, for many otherwise scalable parallel applications, input/output is emerging as a major performance bottleneck. The design of scalable input/output systems depends critically on the input/output requirementsand access patterns for this emerging class of large-scale parallel applications. However, hard data on the behavior of such applications is only now becoming available. In this paper, we describe the input/output requirements of three scalable parallelapplications(electron scattering,terrain rendering, and quantum chemistry) on the Intel Paragon XP/S. As part of an ongoing parallel input/output characterization eort, we used instrumented versions of the application codes to capture and analyze input/output volume, request size distributions, and temporal request structure. Because complete traces of individual application input/output r...
