Real-time resource-sharing under clustered scheduling
2011
Proceedings of the ninth ACM international conference on Embedded software - EMSOFT '11
This paper presents the first suspension-based real-time locking protocols for clustered schedulers. Such schedulers pose challenges from a locking perspective because they exhibit aspects of both partitioned and global scheduling, which seem to necessitate fundamentally different means for bounding priority inversions. A new mechanism to bound such inversions, termed priority donation, is presented and used to derive protocols for mutual exclusion, reader-writer exclusion, and k-exclusion.
