After a long hiatus, Dan and I sat down to look at getting the AliEn system submitting properly into ScotGrid. Battling through OO Perl (yuk!) we found the various points where the system seemed to lack configuration information - this was basically a value for the site BDII to query free slots, a CE queue name and the name of the VO (gridpp). When we'd hacked those values into the LCG.pm AliEn file then things started to look a lot rosier.
However, I think that AliEn is going to want a dedicated queue, because of the way it parses the BDII's output, which inclines us towards setting up a VO for panda sooner rather than later.
