[jsdl-wg] GSA scheduling extensions to JSDL

[Ariel Oleksiak]

Hi Donal,

We consider two issues (related to JSDL) in order to make schedulers 
interoperable: JSDL profile and scheduling attributes.
In JSDL profile we are looking for a common subset of JSDL attributes that a 
scheduler must support (e.g. they are needed for scheduling). So far we 
looked at two schedulers only so we definitely need input concerning others.
Second issue, probably more interesting, is definition of scheduling 
attributes. We came to the conclusion that something like scheduling 
description language would be needed. We need to describe requirements 
concerning time constraints, job dependencies, priorities, etc. First of 
all, currently there is no spec that defines how to specify scheduling 
requirements related to time (earliest start time, deadline, daytime windows 
etc.). So far we proposed a draft of time constraints description. This 
might be potentially considered as JSDL extension, however, SDL was decided 
to be out of scope of JSDL :)
These both issues will be discussed on OGF20. Of course, we could also meet 
together (both groups) to talk about it.

Cheers,
Ariel
