广播式共享存储器──一种新的多计算机系统通讯结构

提出一种用于多机系统节．点机间通讯的新结构──广播式共享存储器．每个节点机都有一个双口ＳＲＡＭ，Ａ口供本节点机“只读”，Ｂ口均连到公共“广播写”总线，供争到总线使用权的节点机广播写数，实现数据通讯．这种多机系统既具有共享存储器便于并行编程的优点，又能显著降低访问共享存储器发生冲突的概率，具有很好的性能价格比。本文所提出的通讯方案已用于由８个ｉ８６０微处理器组成的多机系统中（峰值速度达６４０ＭＦＬＯＰＳ）实验的结果表明，这种方案可使节点机间的通讯速率得到大幅度提高。     

Optimization of memory access for the convolutional neural network training

Batch Normalization (BN) can effectively speed up deep neural network training, while its complex data dependence leads to the serious "memory wall" bottleneck. Aiming at the "memory wall" bottleneck for the training of the convolutional neural network(CNN) with BN layers, an effective memory access optimization method is proposed through BN reconstruction and fused-layers computation. First, through detailed analysis of BN’s data dependence and memory access features during training, some key factors for large amounts of memory access are identified. Second, the “Convolution + BN + ReLU (Rectified Linear Unit)” block is fused as a computational block to reduce memory access with re-computing strategy in training. Besides, the BN layer is split into two sub-layers which are respectively fused with its adjacent layers, and this approach further reduces memory access during training and effectively improves the accelerator’s computational efficiency. Experimental results show that the amount of memory access is decreased by 33%, 22% and 31% respectively, and the actual computing efficiency of the V100 is improved by 20.5%, 18.5% and 18.1% respectively when the ResNet-50, Inception V3 and DenseNet are trained on the NVIDIA TELSA V100 GPU with the optimization method. The proposed method exploits the characteristics of memory access during training, and can be used in conjunction with other optimization methods to further reduce the amount of memory access during training.     

Damping performance of Cu-Zn-Al shape memory alloys in engineering structures

The stress strain curves of two CuZnAI shape memory alloys which have the martensltic transformation temperatures of 50℃ and-10℃ respectively, were measured by using electronic material tester after treated by different heat-treatment conditions. The results show that the area enclosed by hysteresis loop of the CuZnAI shape memory alloy in martensltic state is much larger than that of the alloy in austenltic state with super-elasticity at room temperature. Therefore, the former has better vibration attenuation effect. After being oil-quenched, waterquenched, and step-quenched, the CuZnAI alloy takes on more stable shape memory effect, better super-plasticlty and superelasticity (pseudoelasticity). A CuZnAI shape memory alloy damper was designed, produced and installedto a 2-layer frame structure. In addition, the vibration experiments were made by dynamic data collecting analysis meter. The velocity of vibration attenuation of frame structure with CuZnAI shape memory alloy damper is much faster than that without it. And with the help of CuZnAI shape memory alloy damper, the attenuation period reduces to 1/10 of the original.
