Abstract:
|
Transactional Memory (TM) is a key future technology for emerging many-cores. On the other hand, OpenMP provides a vast established base for writing parallel programs, especially for scientific applications. Combining TM with OpenMP provides a rich, enhanced programming environment and an attractive solution to the many-core software productivity problem.
In this paper, we discuss the runtime environment for supporting our combined TM and OpenMP framework. Through motivating examples, we briefly illustrate how the combined TM/OpenMP can facilitate writing parallel programs. We then discuss issues in runtime environment design. In another contribution, we introduce a set of applications that we specifically developed for our combined TM/OpenMP framework. Using those applications, we show how we can use the rich features provided by TM such as retry to support efficient TM/OpenMP programs. We also include an initial performance analysis of the runtime using the applications. |
