Abstract :
Programming GPUs is challenging for applications with irregular fine-grained communication between threads. To improve GPUs´ programmability and thus extend their usage to a wider range of applications, the authors propose to enable transactional memory (TM) on GPUs via Kilo TM, a novel hardware TM system that scales to thousands of concurrent transactions.
