Embedded processors are about to enter the eight-core era-Linux Enterprise applications-Linux server application information. The following is a detailed description. In addition to the desktop fever field, server and workstation market, the Intel Sandy Bridge-EP architecture is still preparing for the war on embedded devices, with a maximum of eight cores. This will be the first time that an x86 embedded processor has received eight cores (the former version of the Power Architecture launched b

Recently, at the 2016 Intel Life Science Information Technology Forum, a bio-computing accelerator platform called GTX one emerged, sparking new insights into the industry's precision healthcare industry. The GTX one acceleration system, which maximizes the computational power of the FPGA through algorithmic innovation, is equivalent to compressing a supercomputer into a small box, and an FPGA accelerator card can achieve the computational performance of 60 high-performance

Of the CPUs currently produced by Intel, Pentium 4 and Celeron are PC-oriented, Xeon, XEONMP, and Itanium are for workstations and servers. Where Itanium is a completely different 64-bit CPU from other CPUs, the design is not considered for existing Windows applications. While other processors vary in their maximum operating frequency, FSB (front bus frequency), and cache size, the internal design is essentially the same while ensuring software compat

In order to use Oracle RAC 11g version 2nd, you must install the Grid Infrastructure. After the setup inquiry process, the configuration Assistant is launched to configure ASM and Oracle Clusterware. Although this combination of product installation is known as the Oracle Grid Infrastructure, Oracle Clusterware and Automatic Storage Manager are still standa
