Abstract
The advancement of the computer systems enables researchers to process a huge amount of data for various fields at a reasonable cost. However, the data which should be processed and the calculation performance are also increased rapidly. The "ALL-IP concept" is the idea to connect all computer resources flatly with high performance IP network, and high performance computing system for huge data is achieved by the idea. A high performance IP switch, new storage architecture with autonomic function and grid computing technology are key technologies for the new computer systems with the "ALL-IP concept".
