APPARATUS AND METHOD FOR PREDICTING PERFORMANCE ATTRIBUTABLE TO PARALLELIZATION OF HARDWARE ACCELERATION DEVICES

摘要

Disclosed herein are an apparatus and method for predicting performance attributable to the parallelization of hardware acceleration devices. The apparatus includes a setting unit, an operation unit, and a prediction unit. The setting unit divides the time it takes to perform a task into a plurality of task stages and processing stages, and sets one of a parallelization index and target performance. The operation unit calculates the times it takes to perform the stages, and calculates at least one of the ratio of a target parallelization stage in the task and a speed improvement value. The prediction unit calculates an expected performance value or a parallelization index based on at least one of the calculated the times it takes to perform the stages, the calculated ratio of the target parallelization stage, the calculated speed improvement value, and the set target performance.
