Abstract
We introduce a Timed Linda language (T-Linda) which is obtained by a natural timed interpretation of the usual constructs of the Linda model and by adding a simple primitive which allows one to specify time-outs. Parallel execution of processes follows the scheduling policy of interleaving, however maximal parallelism is assumed for actions depending on time. We first define the operational semantics of T-Linda by means of a transition system, then we define a denotational model which is based on timed reactive sequences. The correctness of this model is proved w.r.t. a notion of observables which includes finite traces of actions and input/output pairs.
