Research Abstract

In this study, a basic programming model for unguaranteed memory areas where the data might be lost in physical memory shortage and the APIs for such memory accesses were developed. In the experiments, the parameter settings under a wide variety of synthetic workloads to improve the stability of performance were investigated. In addition, according to the results obtained from the experiments, a memory management framework for cloud computing environments was proposed, which improved the performance dependability in drastic changes in system-wide memory usage.
