Expert Solution & Answer
Chapter 11, Problem 7E
Explanation of Solution
Performance of the system:
- System performance is considered as one of main factor of a processor.
- It is used to determine the speed a problem can be solved.
- It is also used to determine the factors such as number of problems that can be allocated at particular amount of time and also the number of problems that can be handled by the processor.
- The speed of the CPU is a key factor that often decides the performance of the system.
- But this factor speed is applied only to identical architecture and which will be misled at many cases.
- A detailed analysis is made to arrive at a detailed decision for different architecture.
- Ensuring reliability with the users in terms performance certain set of standards are established.
- Benchmarks are being established such that user can compare the metrics to get a clear idea about the performance.
Example:
Whetstone, Dhrystones.
- The main problem with the benchmarks that are obtained is that are very simple in such a way the manufactures are able to optimize their products in a way it is capable to meet their requirements based on the benchmarks derived.
- Thus it would be difficult for its user to obtain a decision because product will be available in the market without any differentiation.
- Thus to make the benchmarks being more meaningful and comprehensive the consortium of computer manufactures created a magazine where the technology are being brought together in the form of SPEC(Standard Performance Evaluation Corporation) in 1988.
- The main objective of the SPEC is to obtain a reasonable and practical means where the performance of the system could be measured.
- SPEC functioned in a structured way such that the functioning was made by splitting them into three thus each committee focused on particular aspect of the process...

If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A.
(a) Give an example of when an application might want to receive such ICMP messages.
(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.
(c) Why might it not be a good idea to send such messages directly back to the originating port P on A?

Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm.
