Transactional Memory
Shared memory parallel architectures present a single unified address space to each processor. Usually the memory is physically distributed across the system but each processor is able to access any part of it through a single address space. The system hardware is responsible for presenting this abstraction to each processor. Communication between processors is done implicitly through normal me...
متن کاملTransactional Memory
Today's methods of writing programs that are executed on shared-memory multiprocessors systems rely mostly on locking mechanism. On one hand, those methods enable programmers to write correct multi-threaded programs that access shared resources; on the other hand, lock usage reduces performance due to suboptimal use of them. In this survey paper we will show several implementations of Transacti...
متن کاملHardware-Supported Transactional Memory
In this report, we describe a number of Hardware Transactional Memory (HTM) designs and their basic mechanisms used for better programmability and higher performance than conventional synchronization techniques based on locking. We compare the systems considering their programming model, hardware design challenges, transactional dataset constraints and forward progress guarantees. As high-speed...
متن کاملExtensible transactional memory testbed
Transactional Memory (TM) is a promising abstraction as it hides all synchronization complexities from the programmers of concurrent applications. More particularly the TM paradigm operated a complexity shift from the application programming to the TM programming. Therefore, expert programmers have now started to look for the ideal TM that will bring, once-for-all, performance to all concurrent...
متن کاملTransactional Memory Today
The term “Transactional Memory” was coined back in 1993, but even today, there is a vigorous debate about what it means and what it should do. This debate sometimes generates more heat than light: terms are not always well-defined and criteria for making judgments are not always clear. This article will try to impose some order on the conversation. TM itself can encompass hardware, software, sp...
