Shared memory consistency models: A tutorial

by Sarita V. Adve, Kourosh Gharachorloo - IEEE Computer , 1996
"... Parallel systems that support the shared memory abstraction are becoming widely accepted in many areas of computing. Writing correct and efficient programs for such systems requires a formal specification of memory semantics, called a memory consistency model. The most intuitive model—sequential con ..."

Memory Consistency Models

by David Mosberger , 1993

"... Abstract: The memory consistency model for a shared-memory multiprocessor specifies the behaviour of memory with respect to read and write operations from multiple processors. Relaxed models that impose fewer memory ordering constraints offer the potential for higher performance by allowing hardwar ..."

Two Techniques to Enhance the Performance of Memory Consistency Models

by Kourosh Gharachorloo, Anoop Gupta, John Hennessy - In Proceedings of the 1991 International Conference on Parallel Processing , 1991
"... The memory consistency model supported by a multiprocessor directly affects its performance. Thus, several attempts have been made to relax the consistency models to allow for more buffering and pipelining of memory accesses. Unfortunately, the potential increase in performance afforded by relaxing ..."

A Framework of Memory Consistency Models

by Weiwu Hu, Weisong Shi, Zhimin Tang , 1998
"... Previous descriptions of memory consistency models in shared-memory multiprocessor systems are mainly expressed as constraints on the memory access event ordering and hence are hardware-centric. This paper presents a framework of memory consistency models which describes the memory consistency model ..."

Defining and Comparing Memory Consistency Models

by Lisa Higham, Jalal Kawash, Nathaly Verwaal - In Proc. of the 10th Int'l Conf. on Parallel and Distributed Computing Systems , 1997
"... Because multiprocessors implement sophisticated memory structures in order to enhance performance, processes can have inconsistent views of memory which may result in unexpected program outcomes. A memory consistency model is a set of guarantees that describes constraints on the outcome of sequences ..."

Programming for Different Memory Consistency Models

by Kourosh Gharachorloo , Sarita V. Adve, Anoop Gupta, John L. Hennessy, Mark D. Hill - JOURNAL OF PARALLEL AND DISTRIBUTED COMPUTING , 1992
"... The memory consistency model, or memory model, supported by a shared-memory multiprocessor directly affects its performance. The most commonly assumed memory model is sequential consistency (SC). While SC provides a simple model for the programmer, it imposes rigid constraints on the ordering of mem ..."

Memory Consistency Models of Bus-Based

by Multiprocessors Jalal Kawash, Jalal Kawash, Lisa Higham , 1996
"... The Partial Orders Framework [3] provides a unified way to specify the memory semantics of distributed systems. This report demonstrates the usefulness of this framework for reasoning about the behavior of the shared memory of existing multiprocessors. Three bus-based machine models are examined: ..."
Abstract - Add to MetaCart
: total ordering, total store ordering, and partial store ordering. A formal and unambiguous description of their memory consistency models is established using the unifying framework. The influence of caches on the memory model is also investigated.

Modular Metatheory for Memory Consistency Models

"... We present a framework based on operational semantics for formalizing shared-memory multithreaded programming languages with relaxed memory consistency models. The key feature of our framework is a division of each system’s semantics into two modules, the program semantics and the heap semantics. Th ..."
