概要

Performance of multiprogrammed memory managment strategies for virtual storage systems is extensively investigated. Detailed simulation models are developed for this purpose. In particular, the working set strategy, which is a representative variable partitioning strategy, is analyzed in the multiprogramming environment approximating the operating conditions of actual systems. Practical usage problems inherent to the strategy are discussed. Investigated are the effect of window size, the performance of the on-demand paging policy compared with that of the pre-loading policy, the effectiveness of controlling the maximum number of pages allocated to a task, etc. In this analysis, the effect of locality set transfers in user programs is evaluated. The local LRU strategy, which is a representative fixed partitioning strategy, is also analyzed for comparison with the working set strategy.
