Q. Show the Programmes for Parallel Systems?
Adding elements of an array using two processor
int sum, A[ n] ; //shared variables
void main ( ){
int i ;
for (i=0; i scanf ("%d",&A[i] ); sum=0; // now create process to be executed by processor P1 fork(1) add (A,n/2,n-1, sum); // process to add elements from index n/2 to - 1.sum is output variable // now create process to be executed by processor P0 add (A,0,n/2-1, sum); join 1 ; printf ("%d", sum); } add (int A[ ], int lower, int upper, int sum) { int sum1=0, i; for (i=lower; i<=upper; i++) sum1=sum1+A[i]; lock sum; sum=sum+sum1; unlock sum ; } In this program last half of array is passed to processor P1 that adds them. For the meantime processor P0 adds the first half of array. The variable sum is locked to avoid inconsistency.
scanf ("%d",&A[i] );
sum=0;
// now create process to be executed by processor P1
fork(1) add (A,n/2,n-1, sum); // process to add elements from index n/2 to -
1.sum is output variable // now create process to be executed by processor
P0 add (A,0,n/2-1,
sum);
join 1 ;
printf ("%d", sum);
}
add (int A[ ], int lower, int upper, int sum)
{
int sum1=0, i;
for (i=lower; i<=upper; i++)
sum1=sum1+A[i];
lock sum;
sum=sum+sum1;
unlock sum ;
In this program last half of array is passed to processor P1 that adds them. For the meantime processor P0 adds the first half of array. The variable sum is locked to avoid inconsistency.
