(a) Give the contents of array x after the execution of the following OpenMP code fragment if possible, or give the error if there is one. Assume that there are 5 threads all together:

(b) Give the output of the following OpenMP code fragment if possible, or give the error if there is one. Assume that there are 4 threads all together:

Q2: Consider the loop Is there loop-carried dependence? If there, please identify it occurs. Can you see a way to eliminate this dependence and parallelize the loop?

Q3:

(a) How may as are printed by the program? 1. 10 as

2. 20 as 3. unknown

(b) How may bs are printed by the program? 1. 10 bs

2. 20 bs 3. unknown

Q4: Given the following code fragment, why is this code a faulty MPI program, explain all errors in this program? Assume that it is executed on two processes

Q5:What makes the following code faulty (not producing the apparent desired behavior)? How could it be fixed?

Q6:Given the following code fragment:

i need help with this please with any question
