In this paper we present our ongoing work on implementing the multi-resource server technology in the Linux operating system running on multi-core architectures. The multiresource server is used to control the access to both CPU and memory bandwidth resources such that the execution of real-time tasks become predictable. We are targeting Legacy applications to be migrated from single to multi-core architectures. We investigate the available techniques and mechanisms that can support our multi-resource servers and we discuss the potential problems that needed to be tackled considering the requirements of legacy applications.
