On real-time STM concurrency control for embedded software with improved schedulability

Mohammed El-Shambakey, Binoy Ravindran

Abstract

We consider software transactional memory (STM) concurrency control for embedded multicore real-time software, and present a novel contention manager for resolving transactional conflicts, called PNF. We upper bound transactional retries and task response times. Our implementation in RSTM/real-time Linux reveals that PNF yields shorter or comparable retry costs than competitors.
