We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). Unlike existing approaches, we consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Also, our model captures dynamics related to the execution of both transactional r...

BACKGROUND Transactional sex is a risk factor for HIV infection. Alcohol use may increase the risk of transactional sex. No nationally-representative studies have examined the relationship between multiple dimensions of alcohol use and transactional sex in women in South Africa. The aim of the study was to examine the relationship between alcohol dependence, binge drinking and frequency of drin...

We promote the use of transactional attributes for modelling business processes in the service-oriented scenario. Transactional attributes have been introduced in Enterprise JavaBeans (EJB) to decorate the methods published in Java containers. Attributes describe “modalities” that discipline the reconfiguration of transactional scopes (i.e., of caller and callee) upon method invocation. An orig...

In this paper, we present a Haskell Transactional Memory benchmark in order to provide a comprehensive application suite for the use of Software Transactional Memory (STM) researchers. We develop a framework to profile the execution of the benchmark applications and to collect detailed runtime data on their transactional behavior. Using a composite of the collected raw data, we propose new tran...

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 ...
