Heterogeneous computing is a new computing model after single-core computing and multi-core parallel computing. The following background description about heterogeneous computing is wrong.

• A.NUMA is a mode of screen structure calculation
• B.Mob's law is getting closer to the physical limit, increasing the difficulty and cost of improving single-core performance
• C.The performance improvement from multi-core practitioners is limited. With the increase in parallelism, the problems of heat dissipation and energy consumption are becoming increasingly prominent
• D.Heterogeneous computing maximizes the performance of each processor, giving the most suitable task to the best computer unit

The following is Engineer A's understanding of LVS cluster, the correct one is.

• A.LVS has three working modes LVS-NAT (address translation), LVS-DR (direct routing), LVS-TUN (tunnel)
• B.LVS commonly used scheduling strategies are, polling scheduling, weighted polling scheduling, minimum number of connections, fast response priority, etc.
• C.LVS cluster is mainly composed of three parts: load scheduler and server pool (server pool/Reslserver) shared storage (shared storage)
• D.LVS is a virtual server cluster, working at the seventh layer of the network system, using IP load balancing technology and the fourth layer based on content request distribution technology

Engineer A first enabled Legacy mode to configure B105. The addressing ability was low and it could not be loaded into more hardware and the boot was slow. Then Engineer A changed to UEFI mode for configuration, which has been significantly improved. Which features of UEFI are highlighted above.

• A.UEFI provides higher performance
• B.UEFI provides greater disk capacity
• C.More convenient batch installation
• D.Faster startup, hibernation recovery
