Decanal Jin Hai from scholastic major angle communicative AMD Barcelona (1)

High-powered computation, reseau computation and fictitious machine technology on one hand the mark that itself is level of science and technology, on the other hand it returns the research that for a lot of need high-powered calculative domain is like the course such as biology, chemical, nuclear energy, gene to provide a basis to develop platform. Accordingly, regard scientific research of a country as horizontal mark, high-powered computation, reseau and fictitious machine technology always get the attention of each country researcher.

In afore-mentioned domains, science of computer of university of Hua Zhongke ability and the group that golden sea professor heads technical prexy and key laboratory of province of reseau computation Hubei are the person above average of domestic academia. Reseau of scientific research of Yo of the state religion in regarding as (ChinaGrid) the forerunner that studies with fictitious machine technology, jin Hai teachs the evolution that also pays close attention to CPU domain very much. The 4 nucleuses processor that is about to roll out code name to be Barcelona in AMD during, our newspaper reporter interviews Jin Hai solely to teach, understanding teachs the angle from the scholar to Jin Hai how processor of nucleus of look upon AMD4.

Systematic framework and power comsumption advantage

Ask: The AMD4 nucleus processor of code name Barcelona is about to release, its a few data had seen all at of all kinds media. Look now AMD is delayed on 4 nucleuses processor used connect controller of framework, compositive memory continuously, exceed the framework such as transmission bus line. From high-powered calculative angle, what kind of view do you have to the framework of this kind of inheritance?

Jin Hai: From the point of the data that gets at present, same framework from odd nucleus, double nucleus outspread to 4 nucleuses, explain it is a bouncy framework, it is with connecting a framework continuously exemple, it maintained already to it before the compatibility of framework of traditional front bus line, eliminate bottleneck, memory bandwidth can amount to compose of bridge of traditional FSB north again 2 times much, the half that is traditional framework only is delayed when answering. Exceed transmission interconnection technology to be able to offer taller bandwidth and lower defer. Additional, i/O data uses alone bus line, increased the handling capacity of CPU, at the same time memory bandwidth can increase as the addition of CPU. Have apparent help to high density computation so.
