Performance Evaluation

In this part, we talk about the primary attributes used to measure the performance of a computer system. Unit 2 of block 3 is totally devoted to performance assessment of parallel computer systems. The performance attributes are:

i)  Cycle time (T): It is the part of time for all the operations of a computer system. It is the opposite of clock rate (l/f). The cycle time is represented in n sec.

ii) Cycles Per Instruction (CPI): dissimilar instructions takes different number of cycles for implementation. CPI is dimension of number of cycles per instruction

iii) Instruction count(Ic): No. of instruction in a program is called instruction count.

If we presume that all instructions have same count of cycles, then the total execution

Time of a program = number of cycle required by one instruction*number of instruction in the program*time of one cycle.

Hence, the execution time

                                                 T=Ic*CPI*Tsec.

Basically the clock frequency of the process is specified in MHz. Also, the processor speed is calculated in terms of million instructions per sec (MIPS).
