Book excerpt: Excerpt from Efficient Synchronization on Multiprocessors With Shared Memory A new formalism is given for read-modify-write (rmw) synchronization opera tions. This formalism is used to extend the memory reference combining mechan ism, introduced in the nyu Ultracomputer, to arbitrary rmw operations. A for mal correctness proof of this combining mechanism is given. General requirements for the practicality of combining are discussed. Combining is shown to be practical for many useful memory access Operations. This includes memory updates of the form mem_val mem_val op val, where op need not be associative, and a variety of synchronization primitives. The computation involved is shown to be closely re lated to parallel prefix evaluation. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: From driving, flying, and swimming, to digging for unknown objects in space exploration, autonomous robots take on varied shapes and sizes. In part, autonomous robots are designed to perform tasks that are too dirty, dull, or dangerous for humans. With nontrivial autonomy and volition, they may soon claim their own place in human society. These robots will be our allies as we strive for understanding our natural and man-made environments and build positive synergies around us. Although we may never perfect replication of biological capabilities in robots, we must harness the inevitable emergence of robots that synchronizes with our own capacities to live, learn, and grow. This book is a snapshot of motivations and methodologies for our collective attempts to transform our lives and enable us to cohabit with robots that work with and for us. It reviews and guides the reader to seminal and continual developments that are the foundations for successful paradigms. It attempts to demystify the abilities and limitations of robots. It is a progress report on the continuing work that will fuel future endeavors.

This book was released on 2018-02-28 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Efficient Synchronization Algorithms Using Fetch and Add on Multiple Bitfield Integers Harrison (see [harrison 86, has proposed the use of combining positive bitfield increments to special add and X processors which would have been substituted for memory. These add and x processors would directly support synchronizations primitives. The value returned by an add and X operation would indicate the state of some lock rather than the actual value of a memory cell modified by fetch-and-add. In contrast, the algorithms presented in this paper do not utilize any special hardware except fetch-and-add.

This book was released on 2015-08-04 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Efficient and Correct Execution of Parallel Programs That Share Memory In this paper, we consider an optimization problem that arises in the execution of parallel programs on shared memory multiple-instruction stream multiple-data stream (MIMD) computers. A program on such a machine consists of many program segments each executed sequentially by a single processor. The processors have access to shared memory, and can execute standard memory access operations on this shared memory. This memory is distributed among many separate memory modules. A network connects processors to memory modules. Delays on this network arc stochastic. Thus, operations issued by a processor to distinct memory modules may not be executed as memory requests on those modules in the order they were issued. For performance reasons, we want to allow one operation to begin before a previous one in the same instruction Our analysis gives a method for determining which operations in a stream may be issued concurrently without changing the semantics of the execution We also consider code where blocks of operations have to be executed atomically. This introduces the necessity of locks. Wc use a conflict graph similar to that used to schedule transactions in distributed databases. Our graph incorporates the order on operations given by the program text, enabling us to do without locks even when database conflict graphs would suggest that locks are necessary. 1. Introduction Programs on shared memory M1MD computers, e.g. the NYU Uliracomputer -GGK] or the IBM RP3 machine (PBG). consist of many program segments each executed sequentially by a single processor. The memory locations accessed by these programs arc either locations in shared memory modules, ot local memory locations, which we call registers. An operation in agiven processor follows one of four basic patterns: (1) read from registers (in that processor) and write to registers; (2) read from registers (in that processor) and write to a single location in a shared memory module; (3) read a single location from a shared memory module and write to registers (in that processor); (4) force a constant to either a register (in that processor) or a shared memory module location. We call a register or a location in a memory module by the generic name variable Thus, an operation consists of a read of zero or more variables followedby a write to one or more variables.

Download or read book Shared Memory Synchronization written by Michael Lee Scott and published by Springer Nature. This book was released on 2024 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zusammenfassung: This book offers a comprehensive survey of shared-memory synchronization, with an emphasis on "systems-level" issues. It includes sufficient coverage of architectural details to understand correctness and performance on modern multicore machines, and sufficient coverage of higher-level issues to understand how synchronization is embedded in modern programming languages. The primary intended audience for this book is "systems programmers"--the authors of operating systems, library packages, language run-time systems, concurrent data structures, and server and utility programs. Much of the discussion should also be of interest to application programmers who want to make good use of the synchronization mechanisms available to them, and to computer architects who want to understand the ramifications of their design decisions on systems-level code
