A anyDim() method is a boolean reduction operation for computing the logical disjunction of the elements of a distributed array of its dimensions, yielding a reduced array with the rank one less than the source. The prototype is

$\displaystyle \begin{minipage}[t]{\linewidth}\small\begin{tabbing}
\verb$ void...
...oolean  ...

where the notation boolean # means a multiarray of arbitrary rank with elements of type boolean. The result of this operation is written in res. The reduction occurs in dimension dimension. The anyDim method is implemented by a schedule object with HPspmd class AnyDim. This class has two constructors with arguments identical to the method above, and has one public method with no arguments called execute(), which executes the schedule. The effective public interface of the AnyDim class is

$\displaystyle \begin{minipage}[t]{\linewidth}\small\verb$ public class AnyDim i...
...ublic void execute () { ... }$\\
\verb$ . . .$\\
\verb$ }$

The source array is source and the result array is res. They will both have elements of type boolean. The reduction occurs in dimension dimension.
