Author: Laurence Field, Markus Schulz, Felix Ehm, Tim Dyce Grid Information Systems are mission-critical components in todays production grid infrastructures. They enable users, applications and services to discover which services exists in the infrastructure and further information about the service structure and state. As the Grid Information System is pervasive throughout the infrastructure, it is especially sensitive to the size of the infrastructure. As a grid infrastructure grows, so does the usage of the information system and there are currently two factors driving this growth. Grid interoperation activities will bring growth shocks to the existing system both in terms of additional information content and end users queries. The paradigm of multi-core processors has the potential to bring exponential growth to the number of execution environments in the infrastructure and hence the number of simultaneous computing activities which will place a significant additional query load. To ensure that the current information systems are able to handle this increase in scale, it is necessary to reevaluate their architectures. This paper presents an improved information system architecture which has the potential to meet these future requirements.
