METHOD AND APPARATUS FOR EXPLOITING THREAD-LEVEL PARALLELISM

摘要

According to one example embodiment, there is disclosed herein uses partial recurrence relaxation for parallelizing DOACROSS loops on multi-core computer architectures. By one example definition, a DOACROSS may be a loop that allows successive iterations executing by overlapping; that is, all iterations must impose a partial execution order. According to one embodiment, the inventive subject matter may be used to transform the dependence structure of a given loop with recurrences for maximal degree of thread-level parallelism (TLP), where the threads can be mapped on to either different logical processors (in a hyperthreaded processor) or can be mapped onto different physical cores (or processors) in a multi-core processor.
