Processor manufacturers build increasingly specialized processors to mitigate the effectsof the power wall in order to deliver improved performance. Currently, database engines have to bemanually optimized for each processor which is a costly and error prone process. In this paper, weprovide a summary of our recent VLDB Journal publication, where we propose concepts to adaptto performance enhancements of modern processors and to exploit their capabilities automatically.Our key idea is to create processor-specific code variants and to learn a well-performing code variantfor each processor. These code variants leverage various parallelization strategies and apply bothgeneric and processor-specific code transformations. We observe that performance of code variantsmay diverge up to two orders of magnitude. Thus, we need to generate custom code for each processorfor peak performance. Hawk automatically finds efficient code variants for CPUs, GPUs, and MIC
