the latter is 10 times faster. It is used to connect GPU nodes in the cluster and provide support for direct access to GPU memory through RDMA. With the latest node Tag feature of YARN, you can specify whether the container runs on the CPU or GPU in the job. Create Caffe-on-Spark: This is a distributed integrated solution they created based on the open source software libraries Apache Spark and Caffe. With it, you can submit deep learning jobs to th

There are many hardware acceleration technologies in the virtualization environment. These technical standards come from industry leaders or various organizations. But what will be enabled when the actual project is implemented? Which of the following features have significantly improved the performance? So what is the significance of the existence of these acceleration technologies? No matter which solution, if you want to enable some acceleration functions, hardware support is required, which

-D technology is a hardware-aided virtualization technology based on the North Bridge Chip, by providing built-in DMA virtualization and IRQ virtualization hardware in the North Bridge, the new I/O virtualization mode is realized, intel VT-D can greatly improve the reliability, flexibility, and performance of I/O in virtual environments. The traditional iommus (I/O memory management units, I/O Memory Management Unit) provides a centralized way to manage all the DMA resources-apart from the tradi

, that is, PCIE, is almost a replica of InfiniBand, and its main strength is still inside the chassis, of course, there can also be standard transfer media extended to the outside of the box. This completely makes InfiniBand a martyr. Just like Christ in Christianity.Later on, InfiniBand was learned by many new technologies, such as using TCP/IP for remote memory access (RDMA). Of course, its Protocol Stack is fixed on dedicated hardware. Nowadays, th

must have at least one Ethernet/TCP connection for synchronous replication, but preferably RDMA. appropriate firewall and router rules to allow for ICMP, SMB (port 445, and 5445 for SMB passthrough) and Ws-man (Port 5985) bidirectional communication between all nodes. The network between servers has sufficient bandwidth to contain the IO write workload and the average round trip delay of 5 milliseconds (for synchronous replication). Asynchronous

The Glusterfs is based on a stackable user space design that provides superior performance for a variety of data loads.Glusterfs supports standard clients running standard applications on any standard IP network, and users can access application data using standard protocols such a

Under the premise of the current network bottleneck, in the nutanix This platform can not fully play the nvme SSD performance, This is also a problem with this system. Flash performance is not good, which means nutanix The future of such platforms may be more appropriate for applications that are not particularly sensitiv

following important benefits: • Almost unlimited capacity: DB2 pureScale Feature provides almost unlimited capacity by supporting on-demand addition and deletion of DB2 members. DB2 pureScale Feature can be expanded to 128 members and has a highly effective centralized management tool that supports a variety of different scaling features. DB2 pureScale Feature also utilizes a technology called Remote Direct Memory Access (RDMA), which provides a very

The update also uses remote Direct memory access (RDMA) technology for the first time, which means that replicas of the virtual machine can be transferred directly from the original server's memory side to the target server's memory without the need for any server
