An appropriate automatic thread decomposition approach is critical for pipelined multithreading (PMT) to maximize pipeline performance with balanced thread size on target multi-core processor. This paper presents an automatic thread decomposition approach, which maps the pipeline thread decomposition problem onto a graph-theoretic framework to construct an optimized DAG with minimal bottleneck node...
Multi-core processors have emerged as predominant architecture. Parallelizing applications into multithreaded ones executing on multiple cores is the key to achieving performance improvements. Recently proposed pipelined multithreading (PMT) techniques have shown great promise to parallelizing general applications. However, significant inter-core communication overheads limit the potential performance...
This paper proposes a new, autonomous and dynamic optimization framework, called a meta-level computation. In this framework, a meta-level processor acquires the execution profile of a base-level processor, i.e. a conventional von Neumann machine, produces the optimized base-level configuration and performs the reconfiguration. We define the meta-level computation model based on the considerations...
