The results of the spec cpu2006 bzip2 benchmark running on an amd barcelona has an instruction count of 2.389e12, an execution t
saw5 [17]

Answer:

CPI = 0.94

Explanation:

The formula for execution time is given below:

Execution time = clock cycles * cycle time

As Execution time = 750 s

clock cycle time = 0.333 ns = 0.333 * 10^-9

so putting these values in the above formula, we get

750 = clock cycles * ( 0.333 * 10^-9 )

clock cycles = 750 / ( 0.333 * 10^-9 )

clock cycles = 2.25 * 10^12

As the results of the spec cpu2006 bzip2 benchmark running on an amd barcelona has an instruction count = 2.389 * 10^12

and the formula for clock cycles is:

clock cycles = number of instructions * CPI

CPI = clock cycles / number of instructions

CPI = 2.25 * 10^12 / 2.389 * 10^12

CPI = 0.94

Explain why Windows and Linux implements multiple locking mechanisms. Describe the circumstances under which they use spinlocks,
galben [10]

Answer:

The description for the given question is described in the explanation section below.

Explanation:

Depending on the needs of the device programmers these OS have various locking frameworks. Spinlocks become beneficial for preemptive multitasking processes during which a thread will operate in such an active loop instead of risking a rest queue latency. Mutexes become beneficial to utility lockers.

  • Solaris 2 employs flexible mutexes, indicating something like this on preemptive multitasking computers, the mutex is introduced with either a spinning switch.
  • Semaphores and state variations are much more effective methods for consistency where a commodity needs to be managed for such a prolonged period of time because spinning is unstable over a prolonged time.

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combinin
Dmitry_Shevchenko [17]

Answer:

Follows are the code to this question:

#include<iostream>//defining header file

using namespace std;// use package

int main()//main method

{

int red,green,blue,x;//declaring integer variable

cin>> red >>green>>blue;//use input method to input value

if(red<green && red<blue)//defining if block that check red value is greater then green and blue  

{

x = red;//use x variable to store red value

}

else if(green<blue)//defining else if block that check green value greater then blue  

{

x= green; //use x variable to store green value

}

else//defining else block

{

x=blue;//use x variable to store blue value

}

red -= x;//subtract input integer value from x  

green -=x; //subtract input integer value from x

blue -= x;//subtract input integer value from x

cout<<red<<" "<<green<<" "<<blue;//print value

return 0;

}

Output:

130 50 130

80 0 80

Explanation:

In the given code, inside the main method, four integers "red, green, blue, and x" are defined, in which "red, green, and blue" is used for input the value from the user end. In the next step, a conditional statement is used, in the if block, it checks red variable value is greater than then "green and blue" variable. If the condition is true, it will store red variable value in "x", otherwise, it will goto else if block.

  • In this block, it checks the green variable value greater than the blue variable value. if the condition is true it will store the green variable value in x variable.
  • In the next step, else block is defined, that store blue variable value in x variable, at the last step input variable, is used that subtracts the value from x and print its value.
