== Semantics ==

The ''ready'' type will force P2P Send to start only if a matching receive has been posted by the target processor. When used in conjunction with the [[nonblocking]] type, communication start will wait until a matching receive is posted. This type acts as a form of handshaking and can improve performance in some uses.

== Example ==

var a:Int::allocated[single[on[1]]];
var b:Int::allocated[single[on[2]]] :: ready[];
var c:Int::allocated[single[on[2]]] :: ready[] :: nonblocking[];
a:=b;
a:=c;

The send of assignment ''a:=b'' will only begin once the receive from process 1 has been issued. With the statement ''a:=c'' the send, even though it is [[nonblocking]], will only start once a matching receive has been issued too.
