[jsdl-wg] g-Eclipse implement sweep extension

[Mariusz Wojtysiak]

Hello!

I'm proud to announce that in g-Eclipse project we are implementing
handling of parametric jobs using JSDL-sweep extension.

Now using our JSDL editor, user can:
1. Create basic JSDL (see 1.CreateJSDL.PNG, 2.CreateJSDLStagers.PNG)

2. Select elements, which will be parametrized using sweep extension
(see 3.CreateParameterSrcURI.PNG, 4.NestedParameters.PNG)

3. As a result user has JSDL with sweep extension (see5.SweepSource.PNG)

Then user can:
4. Submit such parametrized JSDL to any middleware (currently
gLite and GRIA are supported).

As a result individual JSDLs are generated by g-Eclipse and every JSDL 
is submitted to middleware (see 6.SubmittedJobs.PNG)


In first version generation of JSDLs is done on client side, but if
middleware support somehow parametric jobs, we want to send such
parametric-JSDL directly to middleware.

In last g-eclipse release we implemented sweep extension using
http://schemas.ogf.org/JSDL/2007/01/JSDL-sweep what isn't the newest
version of JSDL draft.

There are still missing:
- loops (user can only specify Values in functions)
- error handling (e.g. nothing special happens when user not specify
values for parameter)

In next g-eclipse version we plan to add loops.

What are your plans about sweep specification?

When we can expect specification in stable version, which we could
implement?

If you would like to try g-eclipse, just go to:
