In Speculative Multithreading, data dependence that limits the speedup of speculative parallelization needs to be resolved to achieve a high performance. This paper designs a synchronization execution model, with the support of compiler, to synchronize store and load instructions that frequently have data dependence on each other. We use hardware profiler to gather dependence violation information...
Speculative Multithreading (SpMT) technology is an effective mechanism for parallelizing irregular programs which are hard by conventional approaches through allowing multiple threads to execute in the presence of ambiguous data and control dependences while the correctness of the programs is maintained by hardware support. Although speculative parallelization can potentially deliver significant speedup,...
Speculative Multithreading (SpMT) is an effective mechanism for parallelizing irregular programs which are hard by conventional approaches. SpMT technology can be applied to exploit Thread-Level Parallelism effectively through allowing multiple threads executed in the presence of ambiguous data and control dependences while the correctness of the programs maintained by hardware support. This paper...
Speculative Multithreading (SpMT) has been proposed as a perspective method for sequential programs to benefit from the increasing computing resources provided by Chip Multiprocessors (CMP). This paper analyzes the extraction of ihread-level parallelism from general-purpose programs and presents a speculative multi-threading execution model, Prophet. The architectural support for Prophet execution...
