Before revision:  However, for datacenter (in short, DC) computing workloads, such as Internet services or big data analytics, previous work reports that they have extremely low floating point operation intensity , and the average FLOPS efficiency  is only 0.1\% , while the average IPC is 1.3 (the theoretic IPC is 4 on the Intel Xeon E5600 platform).
After revision:  However, for datacenter (in short, DC) computing workloads, such as Internet services or big data analytics, previous work reports that they have extremely low floating point operation intensity . Our experiments also show that the average FLOPS efficiency is only 0.1\% , while the average IPC is 1.3 (the theoretic IPC is 4 on the Intel Xeon E5600 platform).
