Morris, Johannes and all, Concerning the OGF PGI requirements for Job Description : From the EDGI use case 'Marshal Activities from Service Grid to Desktop Grid', the most important requirements, sorted by decreasing priority, are : JD3 (100) The Job Description document MUST reference all grid entities in conformance to the GLUE specification JD11 (107) Job Description should be only used for Job Description not for any kind of feedback. Job status information should not be communicated with a 'changed JSDL' JD4 (101) The Job Description document specification MUST permit the Client to request automatic data stage-in and stage-out JD22 (116) Clearly separate file and directory in the data-stagings. e.g. within the job description the element should be clearly labeled as file or directory, e.g. different aspect of handling directory or a file The other requirements labeled 'yes' are welcome, EXCEPT the 2 following ones, which generate too much COMPLEXITY in the Execution Service : JD6 (103) The Job Description document specification MUST permit the Client to request that at specified Activity states, the Execution service sets the Activity on 'Hold' [NO] JD8 (105) Job Description supports, 1) service-directed data-staging (i.e. specify data-stagings),2) client-initiated data-staging (i.e. specifiy data-staging but service will do nothing only control whether files existing), 3) manual data-staging (i.e. no specification of data-staging elements) [NO] Best regards. ----------------------------------------------------- Etienne URBAH LAL, Univ Paris-Sud, IN2P3/CNRS Bat 200 91898 ORSAY France Tel: +33 1 64 46 84 87 Skype: etienne.urbah Mob: +33 6 22 30 53 27 mailto:urbah@lal.in2p3.fr -----------------------------------------------------
