Originally, I want to do the following.
// Finally, we set up a distribution
// with one point per place
val Dv_tmp:Dist = Dist.makeUnique(D.places());
val v_dst : DistArray[Array[Double]] =
DistArray.make[Array[double]](Dv_tmp);
finish ateach(pt in Dv_tmp ) {
v_dst(pt) = new Array[double](n,
(q:Point) => {(0.0) as double});
}
// Of course the values for v_dst(pt)(q) change later
// but they stay at the same Place.
// Basically one Array[double] at each place.
val v : Array[double] = v_dst.reduce(??, unit);
The ArrayD_add function was supposed to go into the location marked with ??.
But now I am stating that both arguments have home == here, which is definitely
not the case for v_dst(pt), pt in Dv_tmp.
I guess I need to add some communication by hand, say along the lines of
something like Array[double].raw().copyFrom() ? Suggestions welcome !
