Before revision:  However, for emerging datacenter computing (in short, DC)  workloads, such as internet services or big data analytics, previous work reports on the modern CPU architecture that the average proportion of floating-point instructions only takes 1\% and the average FLOPS efficiency is only 0.1\%, while the average CPU utilization is high as 63\%.
