Virtual I/O caching
Michael Frasca, Ramya Prabhakar, Padma Raghavan, Mahmut Kandemir · 2011
A leading cause of reduced or unpredictable application performance in distributed systems is contention at the storage layer, where resources are multiplexed among many concurrent data intensive workloads. We target the shared storage cache, used to alleviate disk I/O bottlenecks, and propose a new caching paradigm to both improve performance and reduce memory requirements for HPC storage systems.
