We are testing the effectiveness of a branch predictor on the execution of a program. First, we execute the program with the standard branch predictor on the processor, which yields an execution time of 2.25 seconds. Next, we execute the program with our modified (and hopefully improved) branch predictor on the same processor, which produces an execution time of 1.50 seconds. In both cases the execution workload is the same. Using our speedup formula, we know WitrynaTo improve the parallel efficiency (PE) of the ordered-subsets expectation-maximization (OSEM) algorithm for 3D PET image reconstruction, we implemented the algorithm …
