In this example, are these 4 threads all running on different machines?

@afa4 I think these threads may or may not run in different machines. It can be the case that they run on different clusters and need to communicate via network. Or they may be threads of different processes on the same machine each having its own address space. I think the point of this slide is to discuss the abstraction of the message passing model, in which we hope to minimize communication if we cannot share data directly.
