Abstract

Conventional servers have achieved high performance by employing fast CPUs to run compute-intensive workloads, while making operating systems manage relatively slow I/O devices through memory accesses and interrupts. However, as the emerging workloads are becoming heavily data-intensive and the emerging devices (e.g., NVM storage, high-bandwidth NICs, and GPUs) come to enable low-latency and high-bandwidth device operations, the traditional host-centric server architectures fail to deliver high performance due to their inefficient device handling mechanisms. Furthermore, without resolving the architecture inefficiency, the performance loss will continue to increase as the emerging devices become faster.
