The KNL processor is also the first processor to support the new AVX512 instruction set, which has a great acceleration effect for deep learning.While the GPU can also be used as a clustered network, each GPU server is connected via Ethernet or InfiniBand technology, and Intel has developed an Omni-

improve RAC performance, we can start from two aspects: on the one hand, we can improve the cache fusion capability through better interconnected devices, such as G-level private network, you can also use DRA technology such as InfiniBand. On the other hand, you can minimize the cache fusion traffic and reduce the mutual dependencies between instances. Service is developed based on the latter idea. Let's take a look at the partition technology that i

and control the device. Expresscard replaces PCMCIA, which is commonly used in mobile computers. PCI/104, PCI/104-Express, and SCSI are also introduced. Compact PCI should be the plug-in ports that we previously engaged in VxWorks that can be plugged into multiple sections. Its interface is pin and supports hot swapping (hotSwap ). There are three types of hot swapping: 1. Basic hot swapping, which requires operations on the console; 2. Full hot swapping. The system automatically performs hot s

-managed clusters to simplify node management and explore the network plug-and-play function of cluster technology in Oracle Database Grid infrastructure ". Let's face the reality: the Oracle openworld Conference mainly targets technicians, developers, chief information officers, and sales personnel. So what should you do if you are a business engineer and are faced with Oracle experts of up to 50 thousand people and what they say makes you confused? From time to time, the major news announced a

cluster. For random data access, the memory speed is several orders of magnitude higher than that of the hard disk (even the highest-end disk storage system barely reaches 1,000 seek/second ). Second, as the network speed of the data center increases, the cost of memory access is further reduced. Accessing the memory of another machine over the network is cheaper than accessing the disk. As I wrote this article, sun's InfiniBand product line has

However, this solution mainly improves the throughput. The latency improvement may not necessarily meet certain very high requirements. At this time, we should consider a more expensive but more efficient solution: replace the common switch with Inf
