  • Multiple Instruction Issue in the Nonstop Cyclone System
    ~TANDEM Multiple Instruction Issue in the NonStop Cyclone System Robert W. Horst Richard L. Harris Robert L. Jardine Technical Report 90.6 June 1990 Part Number: 48007 Multiple Instruction Issue in the NonStop Cyclone Processorl Robert W. Horst Richard L. Harris Robert L. Jardine Tandem Computers Incorporated 19333 Vallco Parkway Cupertino, CA 95014 Abstract This paper describes the architecture for issuing multiple instructions per clock in the NonStop Cyclone Processor. Pairs of instructions are fetched and decoded by a dual two-stage prefetch pipeline and passed to a dual six-stage pipeline for execution. Dynamic branch prediction is used to reduce branch penalties. A unique microcode routine for each pair is stored in the large duplexed control store. The microcode controls parallel data paths optimized for executing the most frequent instruction pairs. Other features of the architecture include cache support for unaligned double­ precision accesses, a virtually-addressed main memory, and a novel precise exception mechanism. lA previous version of this paper was published in the conference proceedings of The 17th Annual International Symposium on Computer Architecture, May 28-31, 1990, Seattle, Washington.

This chapter presents a historical perspective of the Tandem systems' evolution and provides a synopsis of the company's current approach to implementing these systems. The article does not cover products announced since January 1990. At the hardware level, a Tandem system is a loosely-coupled multiprocessor with fail-fast modules connected with dual paths. A system can include a range of processors, interconnected through a hierarchical fault-tolerant local network. A system can also include a variety of peripherals, attached with dual-ported controllers. A novel disk subsystem allows a choice between low cost-per-byte and low cost-per-access.

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements.

Jim Gray June, 1985 Revised November, 1985 ABSTRACT An analysis of the failure statistics of a commercially available fault-tolerant system shows that administration and software are the major contributors to failure. Various approachs to software fault- tolerance are then discussed notably process-pairs, transactions and reliable storage. It is pointed out that faults in production software are often soft (transient) and that a transaction mechanism combined with persistent process-pairs provides fault-tolerant execution -- the key to software fault-tolerance.

  • Dennis Adams Associates Tandem Concepts
    Dennis Adams a s s o c i a t e s Tandem Concepts: An Introduction for UNIX techies Introduction This document was prepared from some investigation work on the Tandem Non-Stop system. Background to Tandem Tandem was founded as a company to develop fault-tolerant systems in 1976 by ex-Hewlett Packard engineers, and the first Tandem NonStop system was based on HP3000 CPUs with a custom bus called Dynabus to provide fault-tolerance of the I/O and CPU. The Operating System was called Guardian, which implemented message passing on a common stack to ensure resilience. The key architecture of Tandem is the (RPC-like) message-passing mechanism. The kernel automatically re-routes a message from a failing component to a functioning one. This same approach is used both within a system and between systems. In 1983, the FOX fibre-optic interconnect was launched which enabled up to 14 individual nodes to participate in a closely coupled network and share workloads between them. In 1986, FOX II enabled the network to be up to 4 Km distance, as well as introducing NonStop VLX, which increased the Dynabus speed from 13 to 40 MB/s. The same year, NonStop SQL was introduced. 1991 saw the first of several changes of architecture, with the introduction of the MIPS CPU, later replaced by the MIPS R4400 in the NonStop Himalaya K-Series in 1993. Tandem computers introduced the S-Series in 1997. This replaced Dynabus and FOX with a new ServerNet interconnect. ServerNet is a true peer-to-peer network (instead of the ring protocol of the earlier networks) and is the basis of the InfiniBand interconnect architect.

  • Strategic Interactions in Dram and Risc Technology: a Network Approach
    Strategic interactions in dram and risc technology: A network approach Geert Duysters & Wim Vanhaverbeke 93.023 September 1993 MERIT, P.O. Box 616, 6200 MD Maastricht (Netherlands) - telephone (31)43-883875- fax: (31)43-216518 1 STRATEGIC INTERACTIONS IN DRA AND RISC TECHNOLOGY: A NETWORK APPROACH Geert Duysters and WiI Vanhaverbeke1 INTRODUCTION Cooperative agreements have been ignored in business literature for a veiy long time. Only recently, the use of cooperative agreements as part of corporate strategies gained substantial interest. This increase in attention is above all due to the fact that in the last decade the number of cooperative agreements by firms has rocketed. In fact cooperative agreements have outnumbered the fully owned foreign subsidiaries (Contractor and Lorange, 1988). In this paper we will use the term cooperation to denote cooperative agreements between partners which are not connected through (majority) ownership. A cooperative agreement can be seen as an agreement which is positioned between two extremes, arm's length transactions on the one hand and the merger of the two firs on the other hand. Cooperation among companies is usually analyzed in strategic management literature on the dyadic level or on the level of the partcipating firs. Only recently, interest by economists has grown to study cooperative efforts of firs within an inter-organisational network framework (see e.g. Hagedoom and Schakenraad. 1990, 1992, 1993). In high- tech industries where almost all incumbents are linked to each other by means of a network of cooperative agreements, an analysis on the level of the individual players or allances is not appropriate to understand the strategic value of cooperative strategies.

  • Software Fault Tolerance in Computer Operating Systems
    Chapter 11 in Software Fault Tolerance, Michael Lyu, Ed., Wiley, 1995. NASA-CR-1 97999 (NASA-CR-197999) SOFTWARE FAULT N95-24993 TOLERANCE IN COMPUTER OPERATING SYSTEMS (Illinois Univ.) 30 p G3/61 0045355 11 Software Fault Tolerance in Computer Operating Systems RAVISHANKAR K. IYER and INHWAN LEE University of Illinois at Urbana-Champaign ABSTRACT This chapter provides, data and analysis of the dependability and fault tolerance for three operating systems: the Tandem/GUARDIAN fault-tolerant system, the VAX/VMS distributed system, and the IBM/MVS system. Based on measurements from these systems, basic software error characteristics are investigated. Fault tolerance in operating systems resulting from the use of process pairs and recovery routines is evaluated. Two levels of models are developed to analyze error and recovery processes inside an operating system and interactions among multiple instances of an operating system running in a distributed environment. The measurements show that the use of process pairs in Tandem systems, which was originally intended for tolerating hardware faults, allows the system to tolerate about 70% - of defects in system software that result in processor failures. The loose coupling between processors which results in the backup execution (the processor state and the sequence of events occurring) being different from the original execution is a major reason for the measured software fault tolerance. The IBM/MVS system fault tolerance almost doubles when recovery routines are provided, in comparison to the case in which no recovery routines are available. However, even when recovery routines are provided, there is almost a 50% chance of system failure when critical system jobs are involved.

    Fault Tolerance & Reliability CDA 5140 Chapter 3 – RAID & Sample Commercial FT Systems - basic concept in these, as with codes, is redundancy to allow system to continue operation even if some components fail - hot standby refers to components that can fail, being associated with components that run in parallel (i.e. powered up) and can take over upon a failure - cold standby refers to having just one component powered up and others available but powered down (standby) that can be powered up upon detection of failure - once one standby takes over upon failure, either repair the failed unit or replace it, before the new operating component can fail - various techniques for improving system/component reliability: o improve manufacturing or design process to decrease component failure rate o parallel redundancy – sometimes synchronization, if multiple parallel components, can be difficult o cold standby can require complex switching o stage of repairing or replacing components is important RAID - increase of performance for processors & main memory has received considerable attention, unlike secondary storage - secondary storage is primarily a mechanical process & hence performance can only be pushed so far without using multiple parallel components - RAID, redundant arrays of independent disks, provides arrays of disks that can operate independently and in parallel, and is an industry standard so can be used on different platforms and operating systems - if data is on separate disks, then I/O requests can be done in parallel 1 - levels
