<h3>What if I need more nodes than are free?</h3>
For example, say you need 50 nodes but there are only 40 free. In
general, getting this many nodes is going to require intervention
from Testbed Operations, if only so we can ask other experimentors
to free up nodes, if possible. Please send us email if you are not
able to able to get the number of nodes you need for your experiment.
Another alternative is to use the
<a href="tutorial/tutorial.php3#BatchMode">Batch System.</a>
If your experiment is amenable to being batched (does not require
human intervention to start and stop), then you can submit a batch
request, which will be serviced when enough nodes become
available. Typically, you would start out with a few nodes,
getting used to the batch system and creating whatever scripts are
needed to make the experiment batchable. Then scale up to larger
numbers of nodes. Thats the easiest way of getting a lot of nodes!
