1. I think most of us are in agreement that in the big visualizer the
host/lan icons should be replaced by plain boxes and circles. I
think Chad might have even been convinced before he left, after
seeing how nice the little ones looked.
2. We definitely need some smaller scale options for the big topos
arising from vnodes, the ones that Mike was playing with. There
should be some heuristic to decide what the default should be when the
big viz page is first displayed. Ie, doing the really big one
first (100%) is often just a waste of time and annoys the user
while it loads.
3. Non-tweaks (ie, significant work, but maybe not hard): Really big
topos need something better. The Tamara Munzner/then-CAIDA tool
that lets you zoom in on an area would have been just the thing for
that really dense/overlapping one that was out there a week ago.
To support that we need some kind of export and viewer
configuration capability.
(This fits into my vision for a one-stop shop for network expts, where
people will use Elab even for big pure simuations, because it will be
linked in to great computational resources and have all sorts of handy

Something that I would like to be able to do is to run a batch
experiment that builds a disk image, and and at the end of the
batch script, have the disk image dumped. Any clever ideas about
how one might go about doing this?
* Fix /etc/named.conf problem on RON image and build new image.
* Run neato and the visualization code on ops cause of CPU load on
big experiments.
* Change ISO version number.
* Adjust web page width to actual display width the user is using.

BTW: shouldn't we have a "node types" page where people can find out info
about the various machine types (CPU, memory, etc.)?

If you're going to add one, I'd probably vote for doing it per-type
instead of per-node. So in node_types you could set what things are public
and what aren't. Then we also wouldn't need holding expts for nodes of odd
types, and it would be okay to have some of them sitting around free.

Subject: shell env for startup scripts
Date: Mon, 7 Jul 2003 10:43:38 -0600 (MDT)
The shell environment that the tb-set-node-startup script uses can be
quite a bit different from the one you get when logged in remotely. This
can make things kinda complicated when trying to automate things, since
you don't quite know what you gonna get. I'm particularly interested in
the ACE_ROOT/TAO_ROOT variables that are set by the scripts in
* The routes table is a problem. Currently 129000 rows, averaging 86 bytes,
for a total of almost 12megs. That on main, with no virtnodes (1000 node
experiments!). The representation is also grossly inefficient (like,
pid/eid in every one of those rows!), and using text representation of the
IP addresses (src,dst,nexthop,mask). We could probably cut that back by
60%, but its still too much stuff to keep around for every swapped out
experiment. We should run the route setup at swapin, and if the user
wants to see them when its swapped out, we can run the route
calculator on the fly and dump the output to the web page.
* Add routes/events option to web page, since those are not in the
email any longer.
* Other items. We better start saving the thumbnails in the experiment
archive directory too (expinfo). We should also be re-rendering after a
modify. We should also save the XML representation to avoid having to
