Syntax
broadcast[root]
Semantics
This type will broadcast a variable amongst the processes, with the root (source) being PID=root. The variable concerned must either be allocated to all or a group of processes (in the later case communication will be limited to that group.)
Example
function void main() { var a:Int::allocated[multiple[]]; var p; par p from 0 to 3 { (a::broadcast[2]):=23; }; };
In this example process 2 (the root) will broadcast the value 23 amongst the processes, each process receiving this value and placing it into their copy of a.
