ABSTRACT: PetaScale computing platforms need to be coupled with efficient IO subsystems that can deliver commensurate IO throughput to scientific applications. In order to gain insights into the deliverable IO efficiency on the Cray XT platform at ORNL, this paper presents an in-depth efficiency evaluation of its parallel IO software stack. Our evaluation covers the performance of a variety of parallel IO interfaces, including POSIX IO, MPI-IO, and HDF5. Moreover, we describe several tuning parameters for these interfaces and present their effectiveness in enhancing the IO efficiency.

KEYWORDS: Cray XT, Parallel IO, Efficiency, ROMIO, Lustre 1 Introduction

High Performance Computing (HPC) is soon approaching the era of PetaScale computing. Massive Parallel Processing (MPP) platforms such as Lawrence Livermore National Lab’s (LLNL) BlueGene/L [4] and Oak Ridge National Lab’s (ORNL) XT4 (Jaguar) [18] have already reached 100s of TFLOPS. Large-scale data-intensive scientific applications on these platforms demand increasingly higher IO throughputs as well as higher computational capacity. Correspondingly, scalable parallel IO needs to be available for these applications to perform well. In fact, aggregated IO throughput ranging from 10-100 GB/s has been reported for Red Storm and Thunderbird at Sandia National Laboratory, and Tera-10 at CEA in Europe [6], among many others. However, such performance marks are the systems’ peak IO bandwidth, which are usually measured with best suitable parameters for the IO subsystem, while what matters the most to the end users is the deliverable IO bandwidth to their respective scientific applications.

Parallel File Systems ADIOData Models (HDF, PnetCDF)Applications

MPI-IOInterconnects Figure 1 Parallel IO Software Architecutre For the reasons of portability and convenient data representation, HPC systems are often deployed with a varying depth of software stacks such as the basic POSIX syscall interfaces, MPI-IO and HDF5 as shown in Figure 1. Collectively, these layers provide portable abstractions for IO accesses. At the top end, scientific applications perform IO through middleware libraries such as Parallel netCDF [9], HDF [23, 24] and MPI-IO [22], often cooperatively among their processes. Parallel file systems, towards the bottom of the stack, directly serve IO requests by striping file extents and/or IO blocks across multiple storage devices. Obtaining a good collective-IO performance across many processes on top of these software layers is a complex task. It requires not only awareness of the processes' collective data access patterns, but also a thorough understanding of the entire software stack and in particular, the behavior of underlying file systems.

MPI-IO [15] is the IO interface for the popular message passing parallel programming model. It is also a frequently used IO programming interface in scientific applications. As shown in Figure 1, MPI-IO is layered on top of file systems. ADIO [19] is the abstract IO interface of MPI-IO, which is typically implemented with specializations for specific file systems. Together, these programming stacks offer crucial avenues for efficient storage accesses. Numerous techniques have been investigated and implemented to improve the scalability of MPI-IO data operations, such as two-phase IO [20], data sieving [21], and data shipping [13]. Along with these techniques, there is an assortment of tuning parameters for improving the efficiency of different IO access patterns.

All these different IO possibilities raise really important questions to both the application scientists and system designers: what IO interface is appropriate to choose from the portfolio? How to gain the best IO efficiency for a given IO interface? In this paper, we tackle on these questions and present our recent evaluation of IO efficiency of parallel IO stacks over Jaguar. Our evaluation covers the performance of a set of common parallel IO interfaces, including POSIX IO, MPI-IO, and HDF5. Moreover, we describe a variety of tuning parameters and their effectiveness in enhancing the IO efficiency for these interfaces.
