A Compiler-Based Approach for Improving Intra-Iteration Data Reuse
Intra-iteration data reuse occurs when multiple array references exhibit data reuse in a single loop iteration. An optimizing compiler can exploit this reuse by clustering (in the...

A Predicate-based Caching Scheme for Client-Server Database Architectures
We propose a new client-side data-caching scheme for relational databases with a central server and multiple clients. Data are loaded into each client cache based on queries execut...
