What is thread-level speculation?
What is thread-level speculation? Thread-Level Speculation (TLS) refers to an environment where execution threads operate speculatively, performing potentially unsafe operations, and temporarily buffering the state they generate in a buffer or cache. At a certain point, the operations of a thread are declared to be correct or incorrect. What is speculation as it relates to parallelization? Abstract. The most promising technique for automatically parallelizing loops when the system cannot determine dependences at compile time is speculative parallelization. Also called thread-level speculation, this technique assumes optimistically that the system can execute all iterations of a given loop in parallel. What is...
