Abstract: Managing connected data, such as a graph data store, includes a computing device with persistent memory and volatile memory. The computing device stores a graph data store with a plurality of nodes and edges in persistent memory. Each of the edges defines the relationship between at least two of the nodes. The nodes and edges may contain tags and properties containing additional information. In response to a search request query, the computing device generates an iterator object stored in volatile memory with a reference to one or more nodes and/or edges in the graph data store. The split between volatile and persistent memory allocation could be used for other objects, such as allocators and transactions. Other embodiments are described and claimed.

Abstract: A processor includes a processing core to execute an application comprising instructions encoding a transaction with a persistent memory via a near memory cache, wherein the near memory cache comprises a cache line comprising an identifier associated with the transaction and a status flag indicating whether the cache line is committed or uncommitted, and a cache controller operatively coupled to the near memory cache to determine, based on the status flag, what operation is to be performed with respect to contents of the cache line.

Abstract: A processor includes a processing core to execute an application including instructions encoding a transaction with a persistent memory via a volatile cache that includes a cache line associated with the transaction, the cache line being associated with a cache line status, and a cache controller operatively coupled to the volatile cache, the cache controller, in response to detecting a failure event, to, in response to determining that the cache line status that the cache line is committed, evict contents of the cache line to the persistent memory, and in response to determining that the cache line status indicating that the cache line is uncommitted, discard the contents of the cache line.
