This talk discusses the impact of GPUs and hybrid GPU/CPU architectures on data processing. After a brief introduction to databases, we describe several query processing algorithms adapted for GPUs and highlight the challenges that a hybrid system has to address in order to optimize the processing of massively parallel data among CPU and GPU cores. We examine the decision that must be made to determine which part of an algorithm should be executed on the CPUs and which part should be executed on the GPUs. Lastly, we outline several important research challenges in database systems that CPU/CPU architectures could potentially help to overcome, in order to advance the state-of-the-art in query processing.
