Abstract (in Japanese) (See Japanese page) 
(in English) In recent multiprocessor platforms in embadded systems are commonly used. Due to this background,
optimal real-time scheduling algorithms which run at full utilization have been proposed, but such algorithms are
not established yet. Meanwhile, a high schedulability and the schedule success ratio cannot be improved by a
existing simple algorithms, for example, RM(Rate Monotonic). To resolve such problems, the RMZL which based
on global RM is proposed. RMZL takes the merit of RM such as high predictability, low jitter, and low overhead,
and also improves the schedulability and schedule success ratio. In this paper we propose the LP-RMZL based on
RMZL which keeps high schedule success ratio under high load. The simulation evaluation shows that our algorithm
outperforms the RMZL under high load situation.
