Abstract
This paper discusses dynamic performance optimization mechanisms for parallel object oriented database programming languages. When a large number of objects are distributed on a distributed-memory parallel processor, referencing a remote object requires inter-processor communication. If those objects are not allocated properly, it may cause total performance degradation. When those objects are allocated with a biased distribution among PEs, it may cause load imbalance. However, the information necessary for relocating objects must be obtained at runtime since the number of objects on a processor and the topology of objects in a database are unknown at compilation time. This paper proposes a new approach to dynamic performance optimization method, and evaluates the results through simulation tests.
