Abstract
We consider several object sharing synchronization mechanisms including lock-based, lock-free, and wait-free sharing for LNREF [1], an optimal real-time scheduling algorithm on multiprocessors. We derive LNREF's minimum-required space cost for wait-free synchronization using the space-optimal wait-free algorithm. We then establish the feasibility conditions for lock-free and lock-based sharing under LNREF, and the concomitant tradeoffs. While the tradeoff between wait-free versus the other sharing is obvious, i.e., space and time costs, we show that the tradeoff between lock-free and lock-based sharing for LNREF hinges on the cost of the lock-free retry, blocking time under lock-based. Finally, we numerically evaluate lock-free and lock-based sharing for LNREF. © 2007 IEEE.
