Inter-process communication in PaPy. The possible means of IPC between two linked pipers (${\mathcal{P}}_1$, ${\mathcal{P}}_2$) in a PaPy graph are indicated (A), and the dashed allow (B) denotes the possibility of direct IPC via sockets, pipes, shared memory, etc. (Table 3). Communication between local and remote processes utilizes RPyC, as described in the text.
