Using Heuristic Value Prediction and Dynamic Task Granularity Resizing to Improve Software Speculation

<table>The state isolation mechanism (in the figure, we assume that the speculative thread 1 has successfully committed, the speculative thread 2 has failed during committing, and speculative thread 3 has just initialized. Therefore, the figure shows the functions of state isolation mechanism in 3 different cases, namely, copying back CVARs to shared space, discarding the CVAR copies, and copying CVAR to private space).</table>
