Fellow interopers: I mentioned on the call that I have 2 endpoints available, but one of them is still a little raw, so I'll just give out the URL for one and the second will follow next week. The URL is https://wincluster1.cs.virginia.edu/HPCP/HPCPService.asmx The service is a .NET2.0/WSE3 frontend and MS CCS backend. The CA cert for the host is available at: https://www.pki.virginia.edu/ca/rootcert/rootcert.cer Here's an example JSDL doc that can be used: <ActivityDocument> <JobDefinition xmlns="http://schemas.ggf.org/jsdl/2005/11/jsdl"> <JobDescription> <JobIdentification> <JobName>JobName</JobName> <JobProject>JobProject</JobProject> </JobIdentification> <Application> <ApplicationName>ipconfig</ApplicationName> <HPCProfileApplication xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="TaskName" xmlns="http://schemas.ggf.org/jsdl/2006/07/jsdl-hpcp"> <Executable>ipconfig.exe</Executable> <Argument>/all</Argument> <Output>ipconfig.txt</Output> <Error>ipconfig_err.txt</Error> <WorkingDirectory>\\wincluster1\head_node_share\Dev\HPC Profile\HPCP_Out</WorkingDirectory> </HPCProfileApplication> </Application> <Resources> <TotalCPUCount> <UpperBoundedRange>1</UpperBoundedRange> <LowerBoundedRange>1</LowerBoundedRange> </TotalCPUCount> </Resources> </JobDescription> </JobDefinition> </ActivityDocument> *** You can view the resulting output at http://wincluster1.cs.virginia.edu/HPCP-Out/ipconfig.txt All methods are available on this service (though the return from GetFactoryAttributesDocument is a bit sparse). Also, any errors should return SOAPFaults, though their format may be idiosyncratic to my implementation. Glenn
