The default for the pvmd-pvmd communication is based on UDP, whereas the pvmd-task
communication is based on TCP. This is section 10.4 in the UG. I think it's detailed
enough, and there's also a (pretty similar) section in the PVM book.

With pvm_setopt(PvmRoute,PvmRouteDirect) you can use the TCP for the task to
task links.

You can also take a look at the "Recent Enhancements to PVM"-paper:

Hope this is enough

Bye
