Intel 8-core 'Nehalem' server processor

Intel is one of the best company that develops the processors for the computers . All the computer uses the Intel processors for the motherboards. so Intel on Tuesday said it will ship a server chip that contains up to eight processing cores later this year, while IBM showed off a high-end server in the works that uses eight such chips, yielding 64 cores.
Nehalem-EX architecture supports up to eight processors and each processor can integrate up to eight cores.

Intel's Nehalem-EX processor, in production later this year and expected to be shipping in high-end server systems by early 2010, will feature up to eight cores inside a single chip that supports 16 threads, according to Boyd Davis, Intel's general manager of the Server Platforms Marketing Group, speaking at a teleconference on Tuesday.

IBM, which participated in the conference, discussed a server currently under development that uses 64 Nehalem-EX cores (eight processors) and can handle 128 threads, according to Alex Yost, vice president IBM BladeCenter. "We're very excited today to be the first to demonstrate Nehalem-EX," Yost said.

Nehalem-EX will increase the memory slots up to 16 memory slots per processor socket, and offer four high-bandwidth "QuickPath" Interconnect links.

Intel also said the currently-shipping Nehalem server chip is making market gains. Intel's currently-available Xeon 5500, the first server processor based on Intel's Nehalem architecture, will be "greater than half of shipments" for Intel's high-volume two-processor server shipments by August, according to Davis.

"Customer acceptance has been quite strong," Boyd said. "From an introduction at the very end of March to representing the majority of our shipments in the market for two-processor servers by the August time frame," he said.

How To Connect Two Home Computers

Connect two computers is the simplest networking in computer field you just need data cable to connect two computers and nothing else , to connect more than two computers you need extra devices for example hub , switch etc.

If you have only internet connection than this technique is very useful for you because you will be able to use internet connection in both computers
Connecting 2 Computers With Cable

The traditional method to network two computers involves making a dedicated link by plugging one cable into the two systems. Several alternatives exist for networking two computers in this manner:

• Ethernet crossover cable
• Null modem serial cable or parallel peripheral cable
• Special-purpose USB cables

Ethernet - Of the above choices, the Ethernet method is preferred as it supports a reliable, high-speed connection with minimal configuration required. Additionally, Ethernet technology offers the most general-purpose solution, allowing networks with more than two computers to be built fairly easily later. If one of your computers possesses an Ethernet adapter but the other has USB, an Ethernet crossover cable can still be used by first plugging a USB-to-Ethernet converter unit into the computer's USB port.


Serial and parallel - This type of cabling, called Direct Cable Connection (DCC) when using Microsoft Windows, offers lower performance but offers the same basic functionality as Ethernet cables. You may prefer this option if you have such cables readily available and network speed is not a concern. Serial and parallel cables are never used to network more than two computers.

USB - Ordinary USB cables must not be used to connect two computers directly to each other.
Attempting to do so can electrically damage the computers! However, special USB cables designed for direct connection exist that can be used safely. You may prefer this option over others if your computers lack functional Ethernet network adapters.

To make dedicated connections with Ethernet, USB, serial or parallel cables requires
1. each computer have a functioning network interface with an external jack for the cable, and
2. the network settings on each computer appropriately configured
One phone line or power cord cannot be used to directly connect two computers to each other for networking.
