Accelerated computational implementation of reconciliation for continuous variable quantum key distribution on GPU by Shao-ting LIU, Xiao-kai WANG, Da-bo GUO

“…For the low computing speed of reconciliation for current continuous variable quantum key distribution， CPU＆amp;GPU-parallel reconciliation algorithms was designed based on LDPC of SEC protocol to speed up decoding computing.In order to raise decoding speed without sacrifice reconciliation efficiency,a static two-way cross linked list to efficiently store large scale sparse parity matrix was employed.The simulation experimental results show that the speed of the decoding rate reaches 16.4 kbit/s when the channel SNR is over 4.9 dB and the reliability of the 2×10⁵continuous variable quantum sequence,with reconciliation efficiency of 91.71%.The experimental based on the Geforce GT 650 MB GPU and the 2.5 GHz and 8 GB memory CPU hardware platform.Relative to the only CPU platform,computing speed increased by more than 15 times.…”

DESIGN AND TEST OF A MULTI-DIMENSIONAL MICRO-VIBRATION SIMULATOR by WANG Bing, XU ZhenBang, YANG JianFeng, WANG XiaoMing, WU QingWen

“…To simulate the micro-vibration of the space platform such as satellites,space stations and so on,a multidimensional micro-vibration simulator based on the Gough-Stewart configuration was designed.Firstly,the structural design of the multi-dimensional micro-vibration simulator was introduced.The theoretical model of the simulator is established by NewtonEuler’s method.In this model,the situation of misalignment between the origin of the relative reference frame and the barycenter of upper platform and load was considered.Combining with the principle of virtual work,the equations of the natural frequencies and mode shapes could be gained.Secondly,the modal of the simulator was analyzed by the finite element method and the analytical method.The first six natural frequencies and the modal shapes were obtained.The maximum error of FEA simulation is4.17% compared with the mathematical analytical solution.Finally,a prototype of the micro-vibration simulator was manufactured and its performance was testing.The test results indicate that the effective operating frequency of the simulator is up to 100 Hz,meeting the need of the vibration test.…”

Scheduling framework based on reinforcement learning in online-offline colocated cloud environment by Ling MA, Qiliang FAN, Ting XU, Guanchen GUO, Shenglin ZHANG, Yongqian SUN, Yuzhi ZHANG

“…Some reinforcement learning-based scheduling algorithms for cloud computing platforms barely considered one scenario or ignored the resource constraints of jobs and treated all machines as the same type, which caused low resource utilization or insufficient scheduling efficiency.To address the scheduling problems in online-offline colocated cloud environment, a framework named JobFusion was proposed.Firstly, an efficient resource partitioning scheme was built in the cloud computing platform supporting virtualization technology by integrating the hierarchical clustering method with connectivity constraints.Secondly, a graph convolutional neural network was utilized to embed the attributes of elastic dimension with various constraints and the jobs with various numbers, to capture the critical path information of workflow.Finally, existing high-performance reinforcement learning methods were integrated for scheduling jobs.According to the results of evaluation experiments, JobFusion improves the resource utilization by 39.86% and reduces the average job completion time by up to 64.36% compared with baselines.…”

FPGA-Jetson based hardware real-time co-simulation for smart grid by Tong DUAN, Venkata Dinavahi, Tianshi CHENG

“…Smart grid is a power-communication coupled cyber-physical power system (CPPS), where the two-domain coupling features make the real-time simulation difficult.Different from the existing software-based co-simulation methods, a FPGA-Jetson based real-time co-simulation platform for smart grid by leveraging the FPGA’'s programmable computation capability and Jetson’s real-time operating system was designed.The power system simulation was carried out on the FPGA board, the information communication system simulation was completed on Jetson platform, and the two-domain information interaction was simulated through the PCIe channel.By making full use of the computing and data transmission capabilities of each module, the real-time simulation of the combination of power grid and communication network was realized.Finally, the corresponding specific modeling and parameters were designed for the two representative smart grid scenarios: hybrid AC-DC transmission network and micro-grid, the validity and scalability of the proposed real-time co-simulation architecture were verified.…”

Survey of FPGA based recurrent neural network accelerator by Chen GAO, Fan ZHANG

“…Recurrent neural network(RNN) has been used wildly used in machine learning field in recent years,especially in dealing with sequential learning tasks compared with other neural network like CNN.However,RNN and its variants,such as LSTM,GRU and other fully connected networks,have high computational and storage complexity,which makes its inference calculation slow and difficult to be applied in products.On the one hand,traditional computing platforms such as CPU are not suitable for large-scale matrix operation of RNN.On the other hand,the shared memory and global memory of hardware acceleration platform GPU make the power consumption of GPU-based RNN accelerator higher.More and more research has been done on the RNN accelerator of the FPGA in recent years because of its parallel computing and low power consumption performance.An overview of the researches on RNN accelerator based on FPGA in recent years is given.The optimization algorithm of software level and the architecture design of hardware level used in these accelerator are summarized and some future research directions are proposed.…”

Extensible hierarchical codec semantic communication system by Yuyuan ZHANG, Haitao ZHAO, Jibo WEI, Kuo CAO, Yichi ZHANG, Peng LUO, Yueling LIU, Kai MEI

“…Aiming at the problem that most current researches on text semantic communication mainly rely on simulation system for theoretical verification, an extensible hierarchical semantic communication system was proposed by taking advantage of the separation of hierarchical encoding and decoding architecture in semantic level and grammatical level.The system was compatible with the reliable communication technology under the framework of Shannon information through the mode of semantic and syntactic separation, and realized the nested combination of semantic communication and traditional communication.Furthermore, a universal and extensible verification system was built based on the software radio platform to verify the proposed semantic communication system architecture.The verification system took semantic communication software platform as the driving core of hardware drive and algorithm call, integrated the whole process of signal generation, information transmission, data acquisition, decoding and evaluation at the receiving end, and could be further extended for semantic and syntactic level.Finally, the text semantic communication was tested based on this verification system, which verified that it had higher validity and reliability than the traditional communication mode.…”
