Polyhedral Modeling and Analysis of Memory Access Profiles
In this paper, we propose to model memory access profile information as loop nests exhibiting useful characteristics on the memory behavior, such as periodicity, linearly linked m...

Reuse-Driven Tiling for Improving Data Locality
This paper applies unimodular transformations and tiling to improve data locality of a loop nest. Due to data dependences and reuse information, not all dimensions of the iteration...

Optimizing Inter-Nest Data Locality Using Loop Splitting and Reordering
With the increasing gap between processor speed and memory latency, the performance of data-dominated programs are becoming more reliant on fast data access, which can be improved...

The Value of Merge-Join and Hash-Join in SQL Server
Microsoft SQL Server was successful for many years for transaction processing and decision support workloads with neither merge join nor hash join, relying entirely on nested loop...
