All asyncCopy methods in the Array class only allow copying data between an Array and RemoteArray.  What specifically makes an array remote?  Must it be stored at a different place?  If that is the case, how exactly do you obtain a reference to an array that is at a remote place?

You have to use an x10.lang.GlobalRef for it.

Check it out and let me know if you want more clarifications.

Hello,

val arr = new Array[Int](1);

arr(0) = 0;

val remArr = new RemoteArray(arr);

Console.OUT.println(remArr(0));

val glob = GlobalRef(remArr);

val home = here;

for(p in Place.places()) {

if(p != home)  {

at (p) {

arr(0) = 1;

Console.OUT.println(arr(0));

finish Array.asyncCopy(arr, at(glob.home()) glob.apply());

}

break;

}

}

Console.OUT.println(remArr(0));

Is the syntax above the one you were looking for? I expected the last println to print 1 but it prints 0. Could you please tell me where I went wrong.
