Our Two-Path Limited Speculation system PALS speculatively executes one of the top two paths of high frequency in loops.
When the size of thread is small on PALS, the overhead of thread control becomes relatively large, and performance degradation is caused by thread control overhead.
We developed a loop unrolling method for the problem.
However, the dependence distance between dependent variables between threads becomes longer by applying loop unrolling, and the waiting time for receiving the dependent data becomes long.
In this paper, we study a scheduling method that makes waiting times to be short.
We show that the scheduling can achieve up to 3.28 times speed-up by the scheduling method. |
