Hi,
I was trying to do the equivalent of an MPI_Gather using code like this.
finish for ( pt(i) in v_dst ) {
v_loc(i).copyFrom(0,v_dst(pt),0,vsize);
where
static type Array1D = Array[Double]{rank==1};
global val v_dst: DistArray[Array1D]{rank==1};
global val v_loc: Array[Array1D]{rank==1};
- the region for all objects of type Array1D is [0..vsize-1],
- the region for v_loc and v_dst is [0..number_of_places-1],
- the distribution for v_dst maps exactly one point to each place.
The above code runs fine on one place. But on two places, it throws a
x10.lang.BadPlaceException: point (1) not defined at (Place 0).
pt(1) lives on place 1 by definition, so the exception is thrown correctly.
Means - the above code snippet is wrong. I tried about half a dozen variants
of the above, but no avail.
How to do it right ?
