It is better for you and us if you don't just keep hitting the
submit button every few minutes. It wastes your time and floods
us with email (we get every failure message you do!)
Instead, you can now use the
<a href="tutorial/tutorial.php3#BatchMode">Batch System</a>
to queue an interactive job. By submitting your experiment as
a batch job, but without any
<a href="tutorial/tutorial.php3#Startupcmd"><tt>tb-set-node-startcmd</tt></a>
directives in your NS file, the job will be queued until nodes are
available. For most experiments, this means just using your regular
NS file, and checking the Batch Mode Experiment box when you create
the experiment.
When your queued job is swapped in, you will be sent email to
inform you, and you can start working!
<b>Please note</b> that the
experiment will be idle when it is swapped in, and will be
<a href="swapping.html#idleswap">idle swapped</a> if you do not
get things running on the nodes in a short period of time. If your
experiment does get swapped out before you can get to it, you can
always visit the experiment's information page and try again by
using the Queue Batch Experiment menu item.

The batch system may also be used for "queuing" interactive experiments.
By leaving out <tt>tb-set-node-startcmd</tt> commands, an experiment
will be started when enough nodes are available, but then remain active
until you (or the system) swap or terminate it.
