What are XSEDE's working definitions of computational and persistent storage?

On Extreme Science and Engineering Discovery Environment (XSEDE) digital services, the distinction between working storage in support of computation and persistent storage is based on usage patterns. Data associated with computation is considered to require only short-term working storage if it is deleted at the time a researcher's computational allocation is exhausted. If the data remains in storage more than six months after the exhaustion of a project's computational allocation, then it is regarded as residing in persistent storage.
