We address the problem of building scalable transaction management mechanisms for multi-row transactions on key-value storage systems, which are commonly termed as NoSQL systems. We develop scalable techniques for transaction management utilizing the snapshot isolation (SI) model. Because the SI model can lead to non-serializable transaction executions, we investigate two conflict detection techniques...
Investigating the performance of parallel applications at scale on future high-performance computing (HPC) architectures and the performance impact of different architecture choices is an important component of HPC hardware/software co-design. The Extreme-scale Simulator (xSim) is a simulation-based toolkit for investigating the performance of parallel applications at scale. xSim scales to millions...
Due to the increasing complexity of communication infrastructures in the automotive domain, reliable models of embedded system architectures are necessary in order to assist designers in the development process. In this context, transaction level modeling, supported by languages as SystemC, is a promising solution to allow performances of networked architectures to be assessed with different compromise...
Nursing homes usually host large accounts of persons with different levels of dementia. Detecting dementia process in early stages may allow the application of mechanisms to reduce or stop the cognitive impairment. Our ultimate objective is to demonstrate that the use of persuasive techniques may serve to motivate these subjects and induct re-learning mechanisms to stop mental impairment. Nevertheless,...
