Effect and Restrictions

Effect:

On exit, the value of

  res [
$x_0, \ldots , x_{\mbox{\tt dim-1}}, x_{\mbox{\tt dim+1}}, \ldots , x_{R - 1}$]

is true if

  source [
$x_0, \ldots, x_{\mbox{\tt dim-1}}, x_{\mbox{\tt dim}},
 x_{\mbox{\tt dim+1}}, \ldots, x_{R - 1}$]

is true for any allowed values of $x_{\mbox{\tt dim}}$. As implied by the replicated alignment of the result array, results are broadcast in the process dimension associated with dimension dim of the source array.

Value restrictions:

The value of dimension must be in the range 0, ...,$R$-1 where $R$ is the rank of the source array.

Shape restrictions:

The shape of the result array must be obtained from the shape of the source array be deleting dimension dimension.

Alignment restrictions:

The result array must be aligned to the source array, with replicated alignment in dimension dimension.

Containment restrictions:

The source array and the result array must be fully contained in the active progess group.

Overlap restrictions:

In-place updates are not allowed.

Replicated data:

If the source array has replicated mapping, values for particular elements are generally taken from the nearest copy. The definition of ``nearest'' is implementation dependent. Consistent replication of copies in the result array relies on consistency of copies in the source array.
