I have a function which I call using for loop. I want that when My
Java program is run on Dual Core its speed increases by twice and when
it run on Quad core its speed increase 4 time.

Here is the Code I am using.

const NUMBER=1000;
Public int int_x;
Public int[] Array1= new int[NUMBER];

init (){
for (int i=0;i<NUMBER;i++){

function_abc(i);
}
}

// function_abc returns same value for a given Value of "i".

function_abc(int i){
int_x++;
...
...
...
Array1[i]=i*5+int_x;
}

So in the end we get an Array[i] with the formula values. On a single
processor it goes through all the for loop in NUMBER times.

I want on Dual Core the Performance doubles by using Threads. So
function_abc(i); is Called in multiple threads and Speed increases X
times depending on number of X Processors the System has.

How can it be done, any idea.

So for Single Core it will have no spped increase.

For Dual Core Twice Speed

For Quad Core 4 Times speed is seen.

Bye
