Hi gurus,

I have a question concerning the handling of communication
in PVM.

I have an application running with group functions.
When I do some global communication (pvm_bcast, pvm_reduce),
how is the scheme to ditribute the messages?

Is it groupserver->slave1, groupserver->slave2, groupserver->slave3, ...

or something like a tree
			groupserver
			/	\
		slave1		slave2
		/	\	/	\
	   slave3  slave 4   slave 5 slave6

Routing policy is pvmdirect.

Any hints are welcome.

Thanks, gero
