Before revision:  We define BOPS as the average number of BOPs per second, and propose replacing FLOPS with BOPS to measure DC computer systems. On the basis of BOPS, we propose a new Roofline performance model for DC computing , which we call DC-Roofline model, with which we optimize DC workloads with the improvement varying from 119\% to 325\% .
After revision:  We define BOPS as the average number of BOPs is independent of the underlying system and hardware implementation, and can be calculated through automatically analyzing the source code of the workload. Based on the BOPS metric, an upper bound performance model, named DC-Roofline, is proposed for DC computing , which we call DC-Roofline model, with which we optimize DC workloads with the improvement varying from 119\% to 325\% .
