I have a quad processor. I coded something like that in java;
Some.java;
public class Some extends Thread {
private SharedData sharedVal;
private String name;
public Some(SharedData val, String threadName) {
sharedVal = val;
name = threadName;
}
public void run() {
int temp;
while(true) {
temp = sharedVal.GetValue() + 1;
sharedVal.SetValue(temp);
}
}
}
SharedData.java;
public class SharedData {
private int value;
SharedData() {
value = 0;
}
public void SetValue(int d) {
value = d;
}
public int GetValue() {
return value;
}
}
Program.java;
public class Program {
public static void main(String[] args) {
SharedData test = new SharedData();
Some t1 = new Some(test, "thread1");
Some t2 = new Some(test, "thread2");
Some t3 = new Some(test, "thread3");
Some t4 = new Some(test, "thread4");
t1.start();
t2.start();
t3.start();
t4.start();
}
}
I run program and check processor graphics, each processor part looks working around %90.
My question is; if i can use system resources like this, what is the parallel programming? Am i getting it wrong? I saw an example on c# using processor count, what is the deal with that?
