Most widely-deployed parallel file systems (PFSs) implement POSIX semantics, which implies sequential consistency for reads and writes. Strict adherence to POSIX semantics is known to impede performance and thus several new PFSs with relaxed consistency ...

Non-volatile main memory, such as memristors or phase change memory, can revolutionize the way programs persist data. In-memory objects can themselves be persistent without the need for a separate persistent data storage format. However, the challenge ...

Existing share access protocols require the client to retrieve all shares even for read accesses in order to achieve atomic semantics. In cloud storage with widely distributed servers, this implies significant communication latency (from client to the ...

A distributed storage service lets clients abstract a single reliable shared storage device using a collection of possibly unreliable computing units. Algorithms that implement this abstraction offer certain tradeoffs and vary according to dimensions ...

Distributed file systems nowadays need to provide for fault tolerance. This is typically achieved with the replication of files. Existing approaches to the construction of replicated file systems sacrifice strong semantics (i.e., the guarantees the ...
