- Abstract
- In supporting high-performance data processing, performance gap between the computation device and storage prevents the full utilization of the computation resource and causes a system bottleneck. In addition, some big-data applications which require interactive, real-time, and complicated computation need faster data I/O than distributed file systems. So we propose a new cache backend facility called CacheDM for network file system, which utilizes the distributed memory as a cache media in the cluster environment where computing nodes are connected via high speed network. CacheDM can provide low-latency and high-speed cache by supporting direct memory copy based access to the cached data by using RDMA. CacheDM is designed as a cache backend of the FS-Cache, therefore users can use CacheDM and gain its performance advantage without modification of existing application and NFS.
