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).
Define class NP. Problems that can be solved in polynomial time by a nondeterministic TM. Contains all problems in P and some problems possibly outside P.
