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
