| Abstract?Scheduling analysis schemes for multiprocessor plat-forms is a very active research area. Among other proposals, the MrsP protocol has acquired academic relevance due to its speci?c bene?ts. In general words, MrsP proposes a spin-based serialization algorithm for shared resources accesses control, emulating the priority ceiling protocol and acquiring its main properties. In this paper we preliminarily explore how the MrsP protocol could be used to build Semi-Partitioned systems. I. INTRODUCTION Several different approaches have been developed for sup-porting multiprocessors real-time systems. However, none of them has acquired enough relevance, development and over-came the common drawbacks of these approaches. Among others, the main drawbacks of proposed multiprocessor ap-proaches include excessive restrictions on the task model, complexity or run-time overheads. Another point is that none of the most extensively developed approaches has aimed to be general purpose. On the contrary, all approaches have focused only on partitioned or global scheduling approaches and only a few of them on semi-partitioned systems. The same way, main approaches have been constrained to speci?c tasks models. The MrsP protocol [1] was conceived to be a protocol solv-ing the main multiprocessor approaches drawbacks without necessarily restricting the scheduling systems to be partitioned, semi-partitioned or globally scheduled, neither restricting the task model. However, only fully partitioned systems with the sporadic task model using ?xed priorities are addressed in [1]. In this paper we explore a possible approach to semi-partitioned systems [2], where tasks can be statically allocated to processors or be shared among all or a set of them, using the MrsP protocol for shared resources control. The rest of the paper is structured as follows. Section II gives a summary of the main characteristics of MrsP refer-enced on this paper. Then section III presents the main lines of the proposals under development, while section IV presents the preliminary scheduling proposals. Finally some conclusions and future work lines are given. | |
