A Hybrid Query Optimization Engine for GPU accelerated Database Query Processing
M.Sc. Sebastian Breß
Performance demands for database systems are ever increasing and a lot of research focus on new approaches to fulfill performance requirements of tomorrow. GPU acceleration is a new arising and promising opportunity to speed up query processing of database systems by using low cost graphic processors as coprocessors. One major challenge is how to combine traditional database query processing with GPU coprocessing techniques and efficient database operation scheduling in a GPU aware query optimizer. In this project, we develop a Hybrid Query Processing Engine, which extends the traditional physical optimization process to generate hybrid query plans and to perform a cost based optimization in a way that the advantages of CPUs and GPUs are combined. Furthermore, we aim at a database architecture and data model independent solution to maximize applicability.
- HyPE is a hybrid query processing engine build for automatic selection of processing units for coprocessing in database systems. The long-term goal of the project is to implement a fully fledged query processing engine, which is able to automatically generate and optimize a hybrid CPU/GPU physical query plan from a logical query plan. It is a research prototype developed by the Otto-von-Guericke University Magdeburg in collaboration with Ilmenau University of Technology
- CoGaDB is a prototype of a column-oriented GPU-accelerated database management system developed at the University of Magdeburg. Its purpose is to investigate advanced coprocessing techniques for effective GPU utilization during database query processing. It uses our hybrid query processing engine (HyPE) for the physical optimization process.
