The question is incomplete. It can be found in search engines. However, kindly find the complete question below:

Question

Cites as a pitfall the utilization of a subset of the performance equation as a performance metric. To illustrate this, consider the following two processors. P1 has a clock rate of 4 GHz, average CPI of 0.9, and requires the execution of 5.0E9 instructions. P2 has a clock rate of 3 GHz, an average CPI of 0.75, and requires the execution of 1.0E9 instructions. 1. One usual fallacy is to consider the computer with the largest clock rate as having the largest performance. Check if this is true for P1 and P2. 2. Another fallacy is to consider that the processor executing the largest number of instructions will need a larger CPU time. Considering that processor P1 is executing a sequence of 1.0E9 instructions and that the CPI of processors P1 and P2 do not change, determine the number of instructions that P2 can execute in the same time that P1 needs to execute 1.0E9 instructions. 3. A common fallacy is to use MIPS (millions of instructions per second) to compare the performance of two different processors, and consider that the processor with the largest MIPS has the largest performance. Check if this is true for P1 and P2. 4. Another common performance figure is MFLOPS (millions of floating-point operations per second), defined as MFLOPS = No. FP operations / (execution time x 1E6) but this figure has the same problems as MIPS. Assume that 40% of the instructions executed on both P1 and P2 are floating-point instructions. Find the MFLOPS figures for the programs.

Answer:

(1) We will use the formula:

CPU time = number of instructions x CPI / Clock rate

So, using the 1 Ghz = 10⁹ Hz, we get that

CPU time₁ = 5 x 10⁹ x 0.9 / 4 Gh

= 4.5 x 10⁹ / 4 x 10⁹Hz = 1.125 s

and,

CPU time₂ = 1 x 10⁹ x 0.75 / 3 Ghz

= 0.75 x 10⁹ / 3 x 10⁹ Hz = 0.25 s

So, P2 is actually a lot faster than P1 since CPU₂ is less than CPU₁

(2)

Find the CPU time of P1 using (*)

CPU time₁ = 10⁹ x 0.9 / 4 Ghz

= 0.9 x 10⁹ / 4 x 10⁹ Hz = 0.225 s

So, we need to find the number of instructions₂ such that CPU time₂ = 0.225 s. This means that using (*) along with clock rate₂ = 3 Ghz and CPI₂ = 0.75

Therefore, numbers of instruction₂ x 0.75 / 3 Ghz = 0.225 s

Hence, numbers of instructions₂ = 0.225 x 3 x 10⁹ / 0.75 = 9 x 10⁸

So, P1 can process more instructions than P2 in the same period of time.

(3)

We recall that:

MIPS = Clock rate / CPI X 10⁶

So, MIPS₁ = 4GHZ / 0.9 X 10⁶ = 4 X 10⁹HZ / 0.9 X 10⁶ = 4444

MIPS₂ = 3GHZ / 0.75 X 10⁶ = 3 x 10⁹ / 0.75 X 10⁶ = 4000

So, P1 has the bigger MIPS

(4)

We now recall that:

MFLOPS = FLOPS Instructions / time x 10⁶

= 0.4 x instructions / time x 10⁶ = 0.4 MIPS

Therefore,

MFLOPS₁ = 1777.6

MFLOPS₂ = 1600

Again, P1 has the bigger MFLOPS

Describe some of the moral, ethical, and legal issues surrounding responsible use of technology (and the information obtained th

rosijanka [135]

Answer:

Technology must be used in the right manner, and for the right purposes. When the latest in image processing is used to find a new planet through machine learning, we are right. However, when we kill somebody with a gun, we are not right. The bullet can be directed to legs rather than heart, and with continuous love and affection, any heart can be won. Sometimes this is allowed legally, Also it can be ethically correct as some institutions might allow it ethically, and it can be for some morally right as well. However, still, this is not right for some, and that is the almighty. And it's hard to match him morally or ethically. And for him nothing wrong is legal. Coming back to the use of technology in the workplace, you will find that you must follow the ethics of that institution, and your moral value must always be subsidiary to their ethics. And in the 21st century, and particularly in developed domains you will never be asked to sacrifice your moral value, and by the end of next quarter, this might be true for the whole world. Hence, ethics and moral values by then can in all cases be used interchangeably, However, when it comes to being legal, your institution will let you know all the laws, and you need to follow them, and these are applicable to all the institutions, and hence you need not require to sacrifice anything for being legal. Always remember that in the 21st century, you might see some very lethal technologies, and your job in the workplace is to study those technologies with your fullest potential. Issues will arise if you do not work with your fullest potential. And if you will, your moral value will be respected, and you will be easily able to obey their ethics, as no company ever think about even a little bad for their employees. And legally even the director is required to be correct just like you. And what is legal is being decided by the court and not any company. Hence, always try to work with your fullest potential, and never think to harm anybody, or your company. If you do this, you will be the hero of your company very soon.

Explanation:

And remember, the information that you get to know in your company is confidential, and you should not leak it to anybody, and even your relatives. Always keep them hidden inside you, and never ever try to leak them.
