Hello @chasemp as a matter of fact I can. I had written code for the panoramic image viewer reprojection that utilizes the grid. I should be able to apply the same to the zoomviewer. I'll work on it over the weekend if that's fine.

Thank you, @dschwen

Just a note for posterity, another reason this model is less good than farming out the processes is that the load is difficult to quantify for something like this where SGE only has first class insight into the original lighttpd process.

i.e. during all of that qstat only shows:

tools.zoomviewer@tools-bastion-03:~$ qstat
job-ID  prior   name       user         state submit/start at     queue                          slots ja-task-ID 
-----------------------------------------------------------------------------------------------------------------

All righty! I deployed a new version that uses jsub to deploy the processing tasks on the grid. Unfortunately the -once parameter is still unreliable so I might have to add my own locking if it turns out to be a problem.
