Tuple Space<br />

Tuples are placed in <strong>and</strong> retrieved from tuple spaces by function calls, previously<br />
described, that match a pattern from a template. A template is essentially a tuple that is<br />
used to express a pattern. The template:<br />
(? A, 12, ? B)<br />
where A is a string <strong>and</strong> B is a double, matches:<br />
(name, number, fraction) = (“Bob”, 12, 34.56)<br />
However, this template will not match the other tuples in the example above. The<br />
general rules for a Linda tuple were stated previously. This is called an associative<br />
memory because elements or tuples in the memory are accessed by associating them,<br />
synonymously, with a pattern in their content as opposed to being referenced by a<br />
memory address or physical location.<br />
Active tuples in Linda are based on the generative communication model, where<br />
dynamically spawned processes are turned into data upon completion of their task. The<br />
eval(“worker”, worker()) function will leave a tuple in the tuple space with two fields<br />
from the called worker function:<br />
worker(){<br />
// perform task<br />
