The memory with register must be buffer, and the register memory that can be seen now has ECC function, its main application in high-end server and graphics workstation, such as IBM Netfinity 5000.

In short, cloud computing will turn the Internet into a paradise for super computing. "The basic principle of cloud computing is that by distributing computing on a large number of Distributed Computers, rather than local computers or remote servers, enterprise data centers will run more like the Internet.
