Scatter

Syntax

scatter[elements,root]

Semantics

Will send a number of elements (equal to elements) from the root process to all other processes.

Example

var x:array[Int,3]::allocated[multiple[]];
var r:array[Int,12]::allocated[multiple[]];
var p;
par p from 0 to 3
{
   x:(x::scatter[3,1]);
   x:=r;
};

In this example, three elements of array r, on process 1, are scattered to each other process and placed in their copy of r.
