I have recently been made responsible for supporting PVM at our site which
includes a Paragon. Is there any way that an application can determine using
only PVM how many nodes are available to the application on the Paragon.

I am envisaging that our users will be running pvm (and xpvm) on their
own workstation and adding the paragon to the configuration (using manual
start). pvm_config returns the number of hosts only, and I am reluctant to
require applications to have to check if the paragon is included among the
available hosts and if so to spawn a special task on the paragon to do a 
local check for the number of nodes and pass that back to the parent - I would
like the parent to be able to simply check for the paragon, ask pvm how many
nodes and then pvm_spawn that number of tasks on that node.
