Combination of cloud computing and High Performance Computing
If cloud computing is first to package IT into a resource pool, HPC will undoubtedly play a role similar to the resource pool. The development of cloud computing will undoubtedly change people's lives. When cloud computing encounters a high-traffic application load, it naturally needs high-performance computers, such as the 12306 ticket booking system mentio
Editor's note: The biggest experience of this Huawei server evaluation can be summarized as three points: independent research and development, demanding requirements of carrier standards, rapid response to customized products, and configuration standards of world-class vendors. Disclaimer: No server optimization was performed during all tests. The obtained value is not the maximum limit.

Red Hat has been working with intel for a long time. Both parties are committed to providing the most advanced performance, flexibility, and reliability for enterprise-level data centers. Looking back over the past decade, RedHat and Intel have been cooperating with each other since RedHatEnterpriseLinux2.1 supports the x86 architecture, not only promoting open-source development together, it also raised computing and processing to a new level, and eventually made red hat the largest Linux provi
In the Linux system, the software and hardware information of proc file system display system is supplied. If you want to understand the system of CPU suppliers and coherent device information, it can be obtained through the process/proc/cpuinfo file. This article makes a brief summary of the file.Unlike the/proc/cpuinfo file generated by the instruction set (ISA) CPU, the/proc/cpuinfo file based on the X86 instruction set CPU contains the following:processor:0Vendor_id:genuineintelCPU Family:6M

Sometimes you need to collect various information about the server, such as CPU information, memory information, Linux version information, and various software information installed. The following describes how to view the main indicators. 1. view the Linux release information [root @ pcmweb ~] # Cat/etc/issue

How to view cpu, memory, hard disk, and other hardware information in linuxNote: in Linux, you can view detailed information about each cpu in/proc/cpuinfo. However, for dual-core CPUs, two CPUs are displayed in cpuinfo. It is often mistaken for two single-core CPUs.I. linux CPU size
