Performance in real-time main-memory databases

Abstract

Applications that involve real-time databases (in which the access to data must satisfy certain time constraints), are difficult to implement on standard architectural platforms. A major reason concerns the limited memory bandwidth available in standard systems which the precludes high performance necessary in "data-intensive" applications. To address this problem, we propose the use of a logic-enhanced memory (hardware memory enhanced with select programmable processing logic) architecture. We describe experimentation with a limited implementation of a real-time database facility for multiprocessors on a logic-enhanced memory system, and our simulations show that such an approach may provide better performance as compared to standard configurations.
