The Oxford Dictionary defines provenance as “the place of origin, or earliest known history of something.” The term, when transferred to its digital counterpart, has morphed into a more general meaning. It is not only used to refer to the origin

The emergence of byte-addressable persistent (non-volatile) memory provides a low latency and high bandwidth path to durability. However, programmers need guarantees on what will remain in persistent memory in the event of a system crash. A widely ac

Non-volatile memory (NVM) is emerging as a fast byte-addressable alternative for storing persistent data. Ensuring atomic durability in NVM requires logging. Existing techniques have proposed software logging either by using streaming stores for an u

In this paper we examine opportunities arising from the convergence of two trends in data management: in-memory database systems (imdbs), which have received renewed attention following the availability of affordable, very large main memory systems;

A Comparative Study of Implementation Techniques for Query Processing in Multicore Systems

Autor: Stratis D. Viglas

Publikováno v: IEEE Transactions on Knowledge and Data Engineering. 26:3-15

Multicore systems and multithreaded processing are now the de facto standards of enterprise and personal computing. If used in an uninformed way, however, multithreaded processing might actually degrade performance. We present the facets of the memor
