A Performance Oriented Migration Framework For The Grid

At least three factors in the existing migrating systems make them less suitable in Grid systems especially when the goal is to improve the response times for individual applications separate policies for suspension and migration of executing applications employed by these migration systems, the use of pre-defined conditions for suspension and migration and the lack of knowledge of the remaining execution time of the applications. In this paper we describe a migration framework for performance oriented Grid systems that implements tightly coupled policies for both suspension and migration of executing applications. The suspension and migration policies take into account both the load changes on systems as well the remaining execution times of the applications thereby taking into account both system load and application characteristics. The main goal of our migration framework is to improve the response times for individual applications. We also present some results that demonstrate the usefulness of our migrating system.
