Customized OS support for data-processing

For decades, database engines have found the generic interfaces offered by the operating systems at odds with the need for efficient utilization of hardware resources. As a result, most engines circumvent the OS and manage hardware directly. With the growing complexity and heterogeneity of modern hardware, database engines are now facing a steep increase in the complexity they must absorb to achieve good performance. Taking advantage of recent proposals in operating system design, such as multi-kernels, in this paper we explore the development of a light weight OS kernel tailored for data processing and discuss its benefits for simplifying the design and improving the performance of data management systems.
