Specification of distributed jobs

I haven't found in the current specification how to define requirements of distributed jobs, e.g. consisting of multiple
 processes and threads requiring multiple resources and/or processors. Has it been moved out of scope of JSDL 1.0 or 
have I missed it? I also guess that a specification of alternative configurations is not possible, e.g. 4 nodes 4 
processors each OR 1 node, 16 processors?
Additionally, there is no element to specify a type of application distribution, e.g. MPI, OpenMPI, however, I remember 
that you considered this rather as an extension.

Distributed Jobs specification

We have moved this out of scope for the definition of distributed jobs. We are looking for the community to show some 
consistency before adopting it.

The ability to specify alternative configurations for number of processors can actually be done with ranges in the 
Resource definitions, with some extensions.

We do have the ability to define alternative application types that will be adopted by the JSDL team in the future. So 
for now you can use the extension mechanism to do what you have discribed.
