Malcolm, I am not fully understanding your example. Can you please add what would actually be executed given this piece of JSDL? I am wondering whether a relative path would be "good enough" or what else would be missing? The "other end of the spectrum" would be to use the RPC package but this might be overkill. Curious...

Hi,
My apologies if this is referring to an old discussion, but here goes ...
UNICORE supports the concept of an "abstract" hosted application. This means that an application is installed on a remote execution host, and can be referred to via a name, rather than a path to the executable. In JSDL this would look something like:
================================================== <jsdl:JobDescription> <jsdl:Application> <jsdl:ApplicationName>Bash shell</jsdl:ApplicationName> <jsdl:ApplicationVersion>3.1.16</jsdl:ApplicationVersion> <jsdl1:POSIXApplication xmlns:jsdl1="http://schemas.ggf.org/jsdl/2005/11/jsdl-posix"> <jsdl1:Environment name="SOURCE">input.sh</jsdl1:Environment> </jsdl1:POSIXApplication> </jsdl:Application> </jsdl:JobDescription> ==================================================
Any thoughts of how I could support this at the SAGA level? The SAGA job description defines an EXECUTABLE property, but I'm assuming this has to be an actual path.
Regards, Malcolm.
