Abstract
A cluster file system comprises a parallel file system and a plurality of burst buffers, with the burst buffers collectively configured to provide an interface between the parallel file system and compute nodes of a computer system. Each of the burst buffers comprises a virtual file system component and a metadata server component. The virtual file system components of respective ones of the burst buffers collectively implement a virtual file system. Metadata relating portions of the virtual file system to portions of the parallel file system is stored in a distributed manner over the metadata server components of the respective burst buffers. Each burst buffer independently manages its own flash memory, but the burst buffers are configured such that data consistency is ensured across their flash memories. The virtual file system illustratively comprises a parallel log-structured file system (PLFS) and the metadata server components illustratively comprise respective TO forwarding servers.
