Hi gurus,

when I have a pvm application that
operates with group functions, how is the communication
done?


Example: I have a pvm-bcast and 7 hosts.

Does the group-root sends to all hosts serial
1-2 1-3 1-4 1-5 1-6 1-7

or is it in a tree structure

1-2 2-3 2-4 4-5 4-6 3-7
so that some communication can be done ''parallel''? (4-5 and 3-7)

How is this done in pvm-mcast and pvm-barrier?


Any hints are welcome.
Thanks,

Gero
