Shared memory multiprocessors are widely used as platforms for technical and commercial computing [2]. Performance evaluation is a key technology for design in computer architecture. The continuous growth in complexity of systems is making this task increasingly complex [7]. In general, the problem of developing effective performance evaluation techniques can be stated as finding the best trade...

We investigated adult age-differences in timing control of fast vs. slow repetitive movements using a dual-task approach. Twenty-two young (M = 24.23 yr) and 22 older adults (M = 66.64 yr) performed three cognitive tasks differing in working memory load and response production demands and they tapped series of 550-ms or 2100-ms target intervals. Single-task timing was comparable in both groups....

Effects of hibernation on memory were tested in European ground squirrels (Spermophilus citellus). The animals were trained in summer to successfully accomplish two tasks: a spatial memory task in a maze and an operant task on a feeding machine. One group hibernated normally, and the other was prevented from hibernation by maintaining ambient temperature at 22 degrees C. In spring, the same tas...

The aim of this study was to evaluate motor control activity (active vs. passive condition) with regards to wayfinding and spatial learning difficulties in large-scale spaces for older adults. We compared virtual reality (VR)-based wayfinding and spatial memory (survey and route knowledge) performances between 30 younger and 30 older adults. A significant effect of age was obtained on the wayfi...

Circuit quantum electrodynamics, consisting of superconducting artificial atoms coupled to on-chip resonators, represents a prime candidate to implement the scalable quantum computing architecture because of the presence of good tunability and controllability. Furthermore, recent advances have pushed the technology towards the ultrastrong coupling regime of light-matter interaction, where the q...

We propose two resource management methods; a scheduling policy that re ects resource consumption states and a memory-replacement strategy based on page classi cation under distributed shared memory architecture. The performances of the two mechanisms are evaluated by a probabilistic simulation. An instruction-level simulator simulates variety of process sets with nite resources on proposed res...

Background: Previous researches have provided contradictory results about on working memory performance after the coronary artery bypass graft (CABG). In addition, studies have focused on the elderly community. For this reason and with regard to the importance and direct effects of working memory on the quality of life human. This study was designed to compare working memory of young CABG patie...

Even though shared memory multiprocessors are becoming more and more common, it is still a formidable task to achieve high performance on parallel applications. One of the main reasons for this is a high amount of implicit communication generated by the program due to poor structuring of the program. This article shows the importance of performance visualisation in order to spot and find the so...
