All, Here is the idea Donal and I had during the JSDL telecon. We make the Resource element into a Resources element, this discribes the overall requirement for the job. Some elements are prepended with Total others with Individual (and some both). This then deals with the majority of job submissions - if you wish to describe different Resource elements then this can be added in as an extension. Outlined are the changes below: <Resources> <CandidateHosts ... />? <CPUArchitecture .../>? vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv <IndividualCPUSpeed .../>? <OverallCPUTime .../>? <TotalCPUCount .../>? <IndividualCPUCount .../>? <TotalResourceCount .../>? <IndividualPhysicalMemory .../>? <TotalPhysicalMemory .../>? <IndividualVirtualMemory .../>? <TotalNetworkBandwidth .../>? <IndividualNetworkBandwidth .../>? <TotalDiskSpace../>? <IndividualDiskSpace .../>? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ <FileSystem .../>* <ExlusiveExecution .../>? <OperatingSystem .../>? <xsd:any##other>* </Resources>* steve..
