Hardware accelerators implement custom architectures to significantly speed up computations in a wide range of domains. As performance scaling in server-class CPUs slows, we propose the integration of hardware accelerators in the cloud as a way to maintain a positive performance trend. Field programmable gate arrays (FPGAs) represent the ideal way to integrate accelerators in the cloud, since they can be reprogrammed as needs change and allow multiple accelerators to share optimised communication infrastructure. We discuss a framework that integrates reconfigurable accelerators in a standard server with virtualised resource management and communication. We then present a case study that quantifies the efficiency benefits and break-even point for integrating FPGAs in the cloud.
