ORBIT-USER: imaging of nodes.

[Max Ott]

Hi,

Unfortunately you typed something slightly different. You requested
'basline.ndz' which doesn't exist. Now doing that should result in
something a bit more meaningful than a ServiceException with no real
consequences.

As for the duration of imaging. It should really never take more than
20 to 25 minutes to image the entire grid. I just did it and indeed it
got stuck on one node, but the INFO messages were very clear about it:

 INFO exp: Progress(322/0/323): 10/99/100 min(n_17_19)/avg/max (151.971942)

322 of 323 nodes were imaged. The one which didn't make it past the
10% mark was 'n_17_19'.

If you don't need that one, simple ^C out of it. I guess we should add
some more sanity checking code in to do this automatically. But we
first need to fix the reason that 63 nodes didn't come up properly in
the first place.

However, I'm wondering if you really need 400 nodes? If you need less,
and know which ones you want, create a topology file listing all the
nodes you need and then use this one for imaging. Information on that
should be on the wiki somewhere.
