Deriving deadline and period for update transactions has long been recognized as an important problem in real-time database research. Despite years of active study, the state of the art only focuses on scheduling of update or control transaction separately. In this paper, we study the problem of deriving deadlines for update transactions in co-scheduling environment upon uniprocessor platforms. We...
Device-to-device (D2D) communication can effectively meet the demands of high data rate by providing a direct link between two mobile users in cellular networks. In this paper, we analyze the optimal power control for energy efficiency of D2D communication underlaying cellular networks. Based on the stochastic geometry, we firstly use the homogeneous Poisson point process (PPP) to characterize the...
Competition for shared memory resources on multiprocessors is the dominant cause for slowing down applications and making their performance varies unpredictably. It exacerbates the need for Quality of Service (QoS) on such systems. In this paper, we propose a fair-progress process scheduling (FPS) policy to improve system fairness. The strategy is to force the equally-weighted applications to bear...
Dynamic Binary Translation (DBT) has been widely used in various applications. Although new architectures and micro-architectures often create performance opportunities for programmers and compilers, such performance opportunities may not be exploited by legacy executables. For example, the additional general-purpose and XMM registers in the Intel64 architecture do not benefit the IA-32 binaries....
A multi-objective chance constrained programming model (MOCCPM) for electronic reconnaissance satellites scheduling problem (ERSSP) is presented. MOCCPM takes the uncertainties in the course of satellite electronic reconnaissance into account, as well as the capabilities and usage restrictions of the electronic reconnaissance satellites. Then a Monte Carlo simulation based multi-objective extremal...
Binary translation (BT) has been an important approach to migrate application software across instruction set architectures (ISAs). Some architectures, such as X86, allow misaligned data accesses (MDAs), while most modern architectures have the alignment restriction that requires data to be aligned in memory on natural boundaries. In a binary translation system, where the source ISA allows MDA and...
