In this paper, the authors present a framework for various multiprocessor scheduling algorithms by minimal modification of current Real-Time Specification for Java (RTSJ). Although the current version of RTSJ provides a secure platform and rich functionalities for real-time Java applications, it lacks multiprocessor support mechanisms, e.g., absence of functions to support processor affinity, to efficiently utilize multiple processing resources. For this reason, they establish a multiprocessor-aware scheduling framework by using system calls of operating systems to make use of processor affinity, FIFO scheduler, scheduling parameter settings, and precision sleep timer functions.
