Use of parallel construct with private clause, Computer Engineering

Assignment Help:

Q. Use of parallel construct with private clause?

In this example we would see use of parallel construct with private and firstprivate clauses. At end of program i and j remain undefined because these are private to thread in parallel construct.  

#include < stdio.h >

int main()

{

int i, j;

i = 1;

j = 2;

#pragma omp parallel private(i) firstprivate(j)

{

i = 3;

j = j + 2;

}

printf("%d %d\n", i, j); /* i and j are undefined */

return 0;

}

In the subsequent illustration every thread in parallel region determines what part of global array x to work on based on thread number.
