X10-PM: Transparent and Efficient Place Migration for APGAS Language

This paper presents X10-PM, a framework that provides APGAS-based programs with place migration support for flexible and efficient resource management, such as server consolidation and coarse-grained load balancing. X10-PM makes the first attempt to add migration support at the granularity of a place to the X10 programs, which is transparent to the application developers with the help of the X10-PM compiler and runtime. The evaluation results show that the migration overhead is modest. This is mainly because X10-PM chooses global consistent points to ensure consistency of migration, by leveraging the key features of the APGAS model and the X10 language.
