Dear all I have just recently joined this mailing list, and so maybe the question that I am going to raise have already been discussed: my apologies if this is the case. My question concerns the Resource element ... It is not clear to me if/how it is possible to specify not only requirements, but also preferences on resources, for example to allow a smart brokering service to choose among multiple resources matching the resource requirements. If you are familiar with Condor, I am referring to something similar to Requirements and Rank of Condor classads Thanks Cheers, Massimo \\\|/// \\ ~ ~ // (/ @ @ /) -------oOOo-(_)-oOOo---------------------------------- Massimo Sgaravatto INFN Sezione di Padova Via Marzolo, 8 35131 Padova - Italy Tel: ++39 0498277047 Fax: ++39 0498277102 oooO E-mail: massimo.sgaravatto@pd.infn.it ( ) Oooo Home page: http://www.pd.infn.it/~sgaravat --------\ (----( )---------------------------------- \_) ) / (_/
