Re: How many nodes can be in Pelican Cluster?
The last releases allow up to 100 nodes. This is set in the variable MAXNODES in the make_pelican script. One could set that to 254, if needed. So you can use any size private class C network. For a larger network, a little more editing would be needed, I think, but there's no reason why it couldn't be done.
If you want to alter a released version to use a larger network, the scripts in /usr/bin/ with names pelican_* would need to be edited before running pelican_setup.
