Primitive <strong>channels</strong>: evaluate-update<br />
• A primitive channel is one that sup<strong>ports</strong> the evaluate-update<br />
method of access:<br />
– evaluate-update method is designed for simulating<br />
concurrency<br />
– When simultaneous actions occur on the channel (ex.<br />
concurrent write & read from a channel), they have to be<br />
serialized in reality. However, updates to the channel will take<br />
effect only after all the currently active processes are finished<br />
or have come to a synchronization point
