In recent years, column stores (or C-stores for short) have emerged as a novel approach to deal with read-mostly data warehousing applications. Experimental evidence suggests that, for certain types of queries, the new features of C-stores result in orders of magnitude improvement over traditional relational engines. At the same time, some C-store proponents argue that C-stores are fundamentall...

Purpose: To investigate the levels of store-switching for main food shopping consequent on a change in operator for a major superstore. To account for differences amongst switchers and non-switchers and to confirm/reject previous research findings. Design/methodology/approach: A two-phase random household postal survey on main food shopping behaviour was conducted in a central Scottish city. Th...

This paper presents remote store programming (RSP). This paradigm combines usability and efficiency through the exploitation of a simple hardware mechanism, the remote store, which can easily be added to existing multicores. Remote store programs are marked by fine-grained and one-sided communication which results in a stream of data flowing from the registers of a sending process to the cache ...

The simulation of the store separation using the automatic coupling of dynamic equations with flow aerodynamics is addressed. The precision and cost (calculation time) were considered as comparators. The method used in the present research decreased the calculation cost while limiting the solution error within a specific and tolerable interval. The methods applied to model the aerodynamic force...
