Memory Locality in the Age of Virtualization: Optimizing Database Performance in Hidden NUMA Topologies

1. Introduction Modern cloud infrastructure presents a fascinating paradox: as we advance toward more sophisticated hardware architectures, virtualization increasingly obscures these same architectures from the software running within virtual machines. This phenomenon is particularly evident in Non-Uniform Memory Access (NUMA) systems, where memory access times depend on the memory location

Optimizing Range Queries in Search Engines: A Mathematical Framework

Abstract Range queries like value:[0 TO 1000000] present significant performance challenges in search engines. This paper provides a comprehensive mathematical framework for understanding and optimizing range query performance. We present rigorous models for tiered indexing, range decomposition, information-theoretic tier selection, block-skipping probability, and performance optimization in distributed environments. Each
