BlockingMessagePassing

Blocking Message Passing Ipc

The InterProcessCommunications will be handled by a Blocking Message Passing scheme.

Blocking provides a synchronisation between processes :

• A process sending a message is blocked until a receiver processes the message
• A process waiting for a message is blocked until it is sent a message.

Message are transmitted by copy, that is the message being sent is copied from the sender memory space to the receiver memory space.

Messages are fixed sized and very short, say 32 bytes, which I think should be enough, but this is subject to change if necessary.

Some fields in the message may indicate that a bigger memory area is to be copied fom the sender to the receiver.
