Metadata performance in distributed file systems (DFS) is critical, due to the following trends: (a) the growing size of modern storage systems is expected to exceed billions of files and most files are small; (b) over half of the file accesses are …
Fast in-memory key value stores are the keys to building large-scale Internet services. The state-of-the-art solutions mainly focus on optimizing the performance for read-intensive workloads. Nevertheless, a wide range of applications demonstrate a …
The increasing capacity of SSDs requires a large amount of built-in DRAM to hold the mapping information of logical-to-physical address translation. Due to the limited size of DRAM, existing FTL schemes selectively keep some active mapping entries in …
For chip multiprocessor systems (CMPs), the interference on shared resources such as on-chip caches typically leads to unbalanced progress among threads. Because of the inherent synchronization primitives, such as barriers and locks, cores running …
