Revising | We will then discuss the ways in which we measure hardware and software performance before discussing the importance of computing power and how it motivated the switch from a single-core to a multi-core processor. The Classic CPU Performance Equation in terms of instruction count (the number of instructions executed by the program), CPI, and clock cycle time: CPU time=Instruction count * CPI * Clock cycle time or. and a web server benchmark (SPECWeb). The basic idea in this form of Cluster is that if a node fails, then applications and services can be made available to other nodes.
