Charm++ parallel programming system

["Evgeniia Belousova -X (ebelouso - AAP3 INC at Cisco)" <ebelouso AT cisco.com>]

Hello again,

I found out about ++nodelist and ++nodegroup options, which must be used
for running an app on several nodes.

Can you explain the way RTS picks nodes from a group? What if I, for
example, have 40 nodes listed, but my app needs only 10 of them? Will it
just pick the first 10 nodes?
