We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). We consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Our model captures dynamics related to the execution of both (i) transactional read/write memory accesses and ...
The STD experiments in Guatemala from 1946-1948 have earned a place of infamy in the history of medical ethics. But if the Guatemala STD experiments were so "ethically impossible," how did the U.S. government approve their funding? Although much of the literature has targeted the failings of Dr. John Cutler, we focus on the institutional context and research ethos that shaped the outcome of the...
Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway transportation develops increasingly ...
We propose a new design for an energy-efficient hardware transactional memory (HTM) system for power-aware embedded devices. Prior hardware transactional memory designs proposed a small, fully-associative transactional cache at the same level as the L1 cache. We propose an alternative design that unifies the transactional and L1 caches, and provides a small victim cache to reduce effects of cap...
In this paper, Black Scholes’s pricing model was developed to study American option on future contracts of Brent oil. The practical tests of the model show that market priced option contracts as future contracts less than what model did, which mostly represent option contracts with price rather than without price. Moreover, it suggests call option rather than put option. Using t hypothesis test...
Hybrid transactional memory (HyTM) [3] works in today’s systems, and can use future “best effort” hardware transactional memory (HTM) support to improve performance. Best effort HTM can be substantially simpler than alternative “unbounded” HTM designs being proposed in the literature, so HyTM both supports and encourages an incremental approach to adopting HTM. We introduce Phased Transactional...
Concurrent programming holds the key to fully utilizing the multi-core chips provided by CMPs. However, traditional concurrent programming techniques based on locking mechanisms are hard to code and error-prone. Transactional Programming is an attempt to simplify concurrent programming where transactions are the main concurrent construct. Hardware Transactional Memory systems provide hardware s...
With the Internet changing from era Web1.0 of computers’ interaction to era Web2.0 of users’ interaction, the development of transactional community has become the key solution to combine economic value with social value in social commerce. Transactional community is different from traditional social community in its relationship establishment because of the unique motivations of their members....
The principle of voluntarism has essential role in formation of contract, choice of contract party and ascertaining the terms of contract in the law of contract in Iran. However, the position of this principle as for contracts of assignment of government shares in the process of privatization, specifically with respect to the power and authority of contract parties to ascertain the terms of the...
This paper argues that caching, atomicity and layering are fundamental to persistent systems, and that the transactional object cache architecture, as an embodiment of these concerns, provides a foundation for high performance persistent system construction. Central to the paper is a description of the semantics of an abstract transactional object cache architecture that supports a wide range o...
