Evaluation of Load Balancing in Multicore Processor for AnT

Abstract

Operating systems (OSes) that is based on micro kernel architecture have high adaptability and toughness. In addition, multicore processors have been developed along with the progress of LSI technology. By running a micro kernel OS on a multicore processor and distributing the OS server to multiple cores, it is possible to realize load balancing of the OS processing. In this method, transaction processing, which requires a large amount of OS processing, can be provided effectively in a multicore environment. This paper presents evaluations of distributed OS processing performances for various scenarios for AnT operating system that is based on the micro kernel architecture in a multicore environment. In these evaluations, we describe the differences in performance by distribution forms when referring the data in a block. Moreover, we use the Post Mark and Bonnie benchmark tools to evaluate the effects of load balancing for the distribution forms.
