In case of this last issue (which I suspect it is!) the DIRAC administrator of the instance you are using (Daniela / Simon) will be able to tell you exactly what to do. The solution they will probably adopt is to create a new "site" (say for example "LCG.MultiCoreSite.site") for just these multi-core jobs and ask you to submit specifically to this site. This site will automatically have the correct options to request the needed resources (queue length, RAM, # cores, etc) from the site. Then, you will need an additional line in your ganga job along the lines of
j.backend.settings['Destination'] = 'LCG.MultiCoreSite.site'.
Hope this helps!
Yes it does, clarifies a few things and helps me think I'm not too far off the mark! I'd only discovered the Destination setting this morning, which looks like it might be as useful as I'd hoped it would be.
Cheers, Raja.
