Loop recreation for thread-level speculation on multicore processors

Inter‐iteration dependences in loops can hinder loop‐level parallelism. For some loops, existing thread‐level speculation techniques fail to expose their inherent loop‐level parallelism, because some inter‐iteration dependences are too costly to synchronize, predict, pre‐compute and isolate. This pa...
