On Real-Time STM Concurrency Control for Embedded Software with Improved Schedulability

We consider software transactional memory (STM) concurrency control for embedded multicore real-time software, and present a novel contention manager for resolving transac-tional 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
