This function starts a non-blocking receive on a given port port, from a given source node source (or A0AnySource if any node will do), with a given tag tag. A request is posted to receive a message described by format, starting at address, with count elements.
On return of this function, the variable pointed by request contains an opaque request that can be used later to test or wait the completion or check the status of the operation.
