I plotted that log file here:

http://www.ci.uchicago.edu/~benc/tmp/report-test3-20080922-2040-h1383jdc/

The log file seems to suggest that between 5 and 12 jobs are running at 
any one time according to the submit side after about 200 seconds into the 
run.

To begin with, each site will only get two nodes at once; as your run 
progresses successfully on a site, that site will be given more nodes.

Have a look at the graph labelled: 

    execute2 tasks, coloured by site

and you can see how many jobs are sent to each site at once.

You have two sites defined - localhost and teraport. The localhost 
definition looks a bit suspicious, though - the usual swift localhost 
definition never allows more than 2 jobs to run at once, but on your run 
you often have more than that.

What does your sites.xml file look like?
