High performance and real-time capability are very important for control systems including load dispatching office systems with energy management system (EMS) functions. Parallel computing and very large memory (VLM) introduced by general purpose symmetric multi-processor (SMP) computers are required to achieve high-performance computing for EMS applications. However, a performance decline was observed on concurrent execution of EMS applications in our early evaluation. VLM may cause non-preemption and I/O inversion problems that interfere with real-time processing. The main issues addressed in this paper are: (1) adoption guidelines of SMP computers to achieve high performance and (2) design guidelines to realize real-time capability with VLM environment from practical points of view. The verification results show that performance can be improved by 2 times by selecting SMP computers appropriately and that real-time processing can be realized by the guidelines. The results of this study are used in the newly developed load dispatching office system that has been in practical operation.
