    A Simulation Accelerating Method Based on CUDA with Kepler GPU by Bingjun Han, Shiming Huang, Ying Du

    Published 2015-10-01
    “…An accelerating method based on CUDA(compute unified device architecture)with Kepler GPU(graphics processing unit)was proposed to speed up the DFT(discrete Fourier transform)processing in the communication simulation platform.Based on this method,the whole DFT processing was split into subtasks named molecular-subtasks corresponding to communication links and a molecular-subtask was further split into smaller parallel subtasks named atomic-subtasks which correspond to the DFT processing in a link.Then,the atomic-subtasks were processed in parallel by the threads in a GPU kernel function,as well as the molecular-subtasks were processed in parallel via several GPU kernel functions to shorter the simulation time.Simulation results show this method can speed up the DFT processing more than 300 times compared with single thread CPU program and 3 times compared with traditional GPU program.…”

    Scheme of virtual machine trusted migration in cloud environment by Jianbiao ZHANG, Yuanxi ZHU, Jun HU, Xiao WANG

    Published 2018-01-01
    “…With the rapid development of cloud computing,as an advantage of cloud services,virtual machine migration technology has been widely noticed and applied.However,there are some problems about VMs migration which should be solved,such as the complication of authentication of platform and the security issues of data transmission,etc.For these problems,firstly,the existing virtual machine migration scheme based on trusted computing technology was analyzed.Secondly,three secure needs that the virtual machine migration scheme which based on trusted computing technology should meet were proposed:the authenticated platform,confidentiality and integrity preserving transfer and atomicity of the vTPCM.Thirdly,a trusted migration scheme of virtual machines for cloud environment was proposed,in which the virtual machine central migration engine and trusted migration agent were introduced to solve the atomicity protection of vTPCM during the migration process.Finally,the concrete scheme was given with verification.…”
