Abstract

A set of data structures are stored in a distributed shared memory (DSM) component and in persistent storage. The DSM component is organized as a matrix of page. The data structure of the set of data structures occupies a column in the matrix of pages. A recovery file is maintained in the persistent storage. The recovery file consists of entries and each one of the entries corresponds to a column in the matrix of pages by a location of each one of the entries.
