Abstract: "Scientific computation has always been one of the driving forces behind the design of computer systems. As a result, many advances in CPU architecture were first developed for high-speed supercomputer systems, keeping them among the fastest computers in the world. However, little research has been done in storing the vast quantities of data that scientists manipulate on these powerful computers. This thesis first characterizes scientists' usage of a multi-terabyte tertiary storage system attached to a high-speed computer. The analysis finds that the number of files and average file size have both increased by several orders of magnitude since 1980. The study also finds that integration of tertiary storage with secondary storage is critical. Many of the accesses to files stored on tape could have easily been avoided had scientists seen a unified view of the mass storage hierarchy instead of the two separate views of the system studied. This finding was a major motivation of the design of the RAMA file system. The remainder of the thesis describes the design and simulation of a massively parallel processor (MPP) file system that is simple, easy to use, and integrates well with tertiary storage. MPPs are increasingly commonly used for scientific computation, yet their file systems require great attention to detail to get acceptable performance. Worse, a program that performs well on one machine may perform poorly on a similar machine with a slightly different file system. RAMA solves this problem by pseudo-randomly distributing data to a disk attached to each processor, making performance independent of program usage patterns. It does this without sacrificing the high performance that scientific users demand, as shown by simulations comparing the performance of RAMA and a striped file system on both real and synthetic benchmarks. Additionally, RAMA can be easily integrated with tertiary storage systems, providing a unified view of the file system spanning both disk and tape systems. RAMA's ease of use and simplicity of design make it an ideal choice for the massively parallel computers used by the scientific community."

Introduction To Scientific Computing

Part I describes the digital computer in terms of technology and systems design concepts. Chapters 1 and 2 provide certain background information necessary to understand and recognize the characteristics of a computing system designed to solve scientific computing problems, and they also define the role of the digital computer as a modern problem-solving tool. Chapter 3 comprises material helpful for a clear understanding of the remaining chapters, especially those m Part III, and it is presented principally for the sake of definitions and uniform terminology. The material on operating systems has been included since students who have had an introduction to programming may not necessarily have an understanding of operating systems, monitor programs, and such related concepts as input-output control, throughout, turnaround-time, and operating efficiency. This chapter also deals with properties and characteristics of high-level programming languages suitable for scientific problem solving. It is assumed that the reader already knows one of these languages and is familiar with its syntax and external specifications. The intent is to enhance and complement this basic information rather than to teach how to design an artificial language or construct a compiler. An abridged version of Part 1 was taught to students ranging in level from second-year undergraduates in engineering and science and third- and fourth-year undergraduates in applied mathematics to graduate students in engineering.
