-
- Only one transputer is allowed to use the iserver because only one
- transputer should have a link to the host specified in the .cfs-file.
- You **have** to use the reduced library on all nodes **not** connected
- to the host.
-
- If you use the full library on the root transputer you have to use the
- INMOS iserver because it serves the link. In addition you have to take
- care of the two edges connected to the host you find as the first two
- parameters you the process running on the root transputer.
-
- If you use the reduced library on the root transputer you do not need
- the INMOS iserver. There is no more communication between the root
- process and the iserver. You can either send the bootstrap with you own
- server or with the iserver **not** using the option -ss (serve the link).
- In this case the iserver starts the program and terminates.

-
- Yes. That's right. The iserver serves the link and waits on an exit call
- initiated by the root process (exit_terminate()).
