Hi all, is there a wiki available to site admins and VO reps alike, for which write access is 'easily' granted as well? I suppose not all site reps have a CERN account (for WLCG, ATLAS or LCG wiki) and not everybody has a EGI wiki account, I guess. --> what is the best place for the documentation to converge to and how can one get write access to it?

My opinion is that some small team should sit down and decide what the desired behavior is, and then work on implementing this behavior on each of the batch systems. It would be really great if this same behavior is reproduced when passing requirements to an ARC CE or a GRAM 5 CE. >> >> The coordination sounds like a job for EGI, however I think the input to this coordination has to come from a discussion between sites and the users; sites should drive the discussion, as the sites are the parties that understand the use cases from multiple user communities. Since the WLCG multicore TF is already working on related issues, we can probably find at least a subset of the right group of people there.
