XPlacer: Extensible and Portable Optimizations of Data Placement in Memory

Chunhua Liao

Executive Summary

We plan to develop a solution to the well-known data placement problem caused by the growing data processing demands of increasingly complex and heterogeneous computing systems. The resulting compiler and runtime techniques will ensure that the applications that support national missions can be adapted to emerging extreme-scale architectures with complex memory hierarchies.
