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:

int i, p, x[5] = {1,1,1,1,1}, 

 y[5]={0,1,2,3,4}; #pragma omp parallel private (p) { 

 p=5; #pragma omp for 

 for (i=0; i<5; i++) x[i]=y[i]+p; 

} /* omp end parallel */ 

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:

int i; double sum = 0.0; #pragma omp parallel for reduction(+:sum) 

 for (i=1; i <= 4; i++) sum = sum + i; 

printf("The sum is %lf ", sum); (c) 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:

 int i; double sum; #pragma omp parallel private (sum) { 

 sum = 0.0; for (i=1; i <= 4; i++) 

 sum = sum + i; printf("The sum is %lf ", sum); 

}

(d) 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:

 int i; double sum = 0.0; #pragma omp parallel shared (sum) { 

 for (i=1; i <= 4; i++) sum = sum + i; 

 } printf("The sum is %lf ", sum); 

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

 int i; double sum = 0.0; #pragma omp parallel private (sum) { 

 for (i=1; i <= 4; i++) sum = sum + 1; 

 } printf("The sum is %lf ", sum);
