AgentSphereにおけるマルチスレッド型エージェントの強マイグレーション機構

Abstract

In AgentSphere, in addition to weak migration, strong migration is also adopted as the move manner of the agent. Although the weak migration which saves the information in a heap area and moves to another JVM by using a serialization function is realizable in Java, the function which saves the information in a stack area and program counter is not supported. Therefore, it is necessary to implement the function to save these two important information by a certain means. In the conventional AgentSphere, although strong migration of a single thread agent was implemented using the method of source code conversion, it was not implemented that the multithreaded agents move all together by a strong migration manner. Moreover, reducing the source code conversion overhead as much as possible was required. So, in this paper, in order to reduce the conversion overhead and to implement the strong migration of multithreaded agents, a new strong migration manner which used Javaflow is proposed.
