ABSTRACT
<p><b>Abstract</b>—We study the most general communication paradigm on a multiprocessor, wherein each processor has a distinct message (of possibly distinct lengths) for each other processor. We study this paradigm, which we call <it>chatting</it>, on multiprocessors that do not allow messages once dispatched ever to be delayed on their routes. By insisting on <it>oblivious</it> routes for messages, we convert the communication problem to a pure scheduling problem. We introduce the notion of a <it>virtual chatting schedule</it>, and we show how efficient chatting schedules can often be produced from efficient virtual chatting schedules. We present a number of strategies for producing efficient virtual chatting schedules on a variety of network topologies.</p>
