Balancing Fairness and Efficiency for Cache Sharing in Semi-external Memory System
Shanjiang Tang, Qifei Chai, Ce Yu, Yusen Li, Chao Sun · 2020
Data caching and sharing is an effective approach for achieving high performance to many applications in shared platforms such as the cloud. DRAM and SSD are two popular caching devices widely used by many large-scale data application systems such Hadoop and Spark. Due to the limited size of DRAM as well as the large access latency of SSD (relative to DRAM), there is a trend of integrating DRAM and SSD (called semi-external memory) together for large-scale data caching.
