Facilitation of search, list, and retrieval operations on persistent data set using distributed shared memory

A method for facilitating search, list and retrieval operations on a persistent data set using a distributed shared memory (DSM) by a processor device, comprising:

• using the DSM to store a plurality of data structures, such that updates, deletions and insertions are applied to both the persistent data set and the DSM, and the search, list and retrieval operations are processed directly from the DSM;
• and
• storing a data structure of the plurality of data structures in the persistent data set by:
• defining a first DSM page to include an identifying search key of the data structure, and
• defining a second DSM page to include at least one updatable property of at least one of the plurality of data structures;
• wherein the first and second DSM pages are assigned as an occupied column in a two-row matrix in the DSM.
