Consider a multiprocessor system and a multithreaded program written using the many- to-many threading model. Let the number of user-level threads in the program be greater than the number of processors in the system. Discuss the performance implications of the following scenarios.

1. The number of kernel threads allocated to the program is less than the number of processors.

2. The number of kernel threads allocated to the program is equal to the number of processors.

3. The number of kernel threads allocated to the program is greater than the number of processors but less than the number of user- level threads.

Answer #1

Answer-

1)- The individual processors would keep going since the hardware mappings only kernel threads to processors and non user-level threads to processors.
2)- It is applicant that every the CPUs strength be converted at the same time. Still, when a kernel object blocks inwardly the kernel the related to processor would stay on operation.

3)- A blocked kernel thread could be switched down in prefer to some other kernel thread that is fit to carry through, thereby modifying the utilization of the multiprocessor system.

Use C++ Write a program that first reads in how many whole numbers the user wants to sum, then reads in that many whole numbers, and finally outputs the sum of all the numbers greater than zero, the sum of all the numbers less than zero (which will be a negative number or zero), and the sum of all the numbers, whether positive, negative, or zero.

Consider the human capital growth model. Let us make the following changes. Depending on whether the current calendar year is an odd or even number, the efficiency parameter of the human capital accumulation technology changes between 5.15 and 2.04. In particular, when the calendar year is an odd number (for example in years 1 and 3) the parameter b is 5.15 and z is 6. However, in even years (for example in years 2 and 4) the parameter is 2.04...

Assume each country has the same preferences, and technologies are such that: HOME: 1 unit of B requires 2 units of labor; 1 unit of P requires 18 units of labor FOREIGN: 1 unit of B requires 3 units of labor; 1 unit of P requires 5 units of labor. A. If trade is introduced between these...
