Available in PDF, EPUB and Kindle. Book excerpt: "Multithreaded programming requires synchronization, to coordinate access to shared resources. As more and more processor cores become available on a single machine, synchronization tends to be the performance bottleneck of many multithreaded programs. This thesis focuses on two important synchronization scenarios: lock-based critical sections and transactional atomic blocks. Since speculation is a well-known means of increasing parallelism among concurrent executions that are usually but not always independent, this thesis first explores the manual addition of speculation to lock-based critical sections (in concurrent data structures). With simple language extensions accompanied by compiler assistance, a technique which we refer to as CSpec, the programmer can exploit high-level program knowledge to move speculative work out of lock-based critical sections, thereby improving scalability while still maintaining correctness. Speculation is also a major approach to improved parallelism in transactional memory systems. Frequent failures of speculative execution, however, may render the technique unprofitable. In recently emerged best-effort hardware transactional memory, speculation fails mainly due to two reasons: hardware overflow and data conflicts. In this thesis we develop a programming technique and compiler support, ParT, to reduce the duration and memory footprint of hardware transactions, leading to lower abort rates while preserving deadlock-free composability. To reduce the incidence of conflict, we propose an automatic, high-level mechanism, Staggered Transactions, that uses advisory locks to serialize (just) the portions of the transactions in which conflicting accesses occur. In all proposed techniques, compiler assistance is essential to maintaining ease of programming. We thus conclude that compiler assistance can significantly improve speculation in multithreaded systems"--Pages vii-viii.
Download or read book Single program Speculative Multithreading SPSM Architecture Compiler assisted Fine grained Multithreading written by International Business Machines Corporation. Research Division and published by . This book was released on 1995 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Recent limit studies on instruction-level parallel processing, based on non-numeric applications, have reported significant performance gains from speculative execution of multiple control flows. This paper describes a new single-program speculative multithreading (SPSM) architecture, which can be viewed as an extension of any existing single- thread architecture. It enables speculative fetch, decode, and execution from multiple program locations simultaneously. Instruction threads are generated at compile-time using control dependence analysis. Inter-thread data dependences are also analyzed at compile-time. However, resource binding of instructions is performed only at run time, to offer binary compatibility across different implementations. New thread generation algorithms, being prototyped in a version of the TOBEY compiler, are also described. The SPSM architecture includes novel fork/suspend instructions which are used to identify independent instruction threads, and also to specify compile-time control flow speculations associated with inter-thread dependences."

Download or read book Application of Compiler Assisted Multiple Instruction Rollback Recovery to Speculative Execution written by National Aeronautics and Space Administration (NASA) and published by . This book was released on 2018-08-17 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speculative execution is a method to increase instruction level parallelism which can be exploited by both super-scalar and VLIW architectures. The key to a successful general speculation strategy is a repair mechanism to handle mispredicted branches and accurate reporting of exceptions for speculated instructions. Multiple instruction rollback is a technique developed for recovery from transient processor failure. Many of the difficulties encountered during recovery from branch misprediction or from instruction re-execution due to exception in a speculative execution architecture are similar to those encountered during multiple instruction rollback. The applicability of a recently developed compiler-assisted multiple instruction rollback scheme to aid in speculative execution repair is investigated. Extensions to the compiler-assisted scheme to support branch and exception repair are presented along with performance measurements across ten application programs. Alewine, N. J. and Fuchs, W.
