[occi-wg] Using OCCI with infrastructure frameworks and local batch adapters [Re: Sessions at OGF 34]

[Alan Sill]

Hi Gregor,

I surveyed a few of the group members and leaders on these topics, and  
the overall sense seems to be that while the interfaces to framework  
projects such as OpenStack, OpenNebula etc. do exist and and maturing,  
there are not yet any projects underway to make direct connections  
from OCCI to local batch resource managers such as the ones that you  
mention.

In other words, there is not yet (and not immediately on the horizon)  
a project to introduce the OCCI equivalent of GRAM for batch job  
submission.

That is not to say that such an interface is impossible, but it might  
require the same sort of care that went into development of LRM  
adapters for GRAM, and possibly is a design project.

Questions b) - d) that you posed relate to some of the above active  
projects.  My understanding is that these topics will be discussed at  
this week's OCCI-WG teleconference, details of which are at the link  
below.

In particular, B) and D) are active, but work across the board on  
Eucalyptus has been hard to motivate, as in most people's experience  
the current Eucalyptus framework has been buggy, hard to work with and  
not very scalable, so has been a low priority to get working.  (If we  
understand this to be a surrogate for working with EC2-style  
interfaces and therefore for working with Amazon, it might be possible  
to generate more enthusiasm, but the work so far has been on truly  
open interfaces.)

The meetings are scheduled  Wednesdays 10am EDT, 4pm CET, 3pm BST,  
Thursday 12am Tokyo according to the group wiki page.  Can I suggest  
that you join them to pursue some or all of these topics with the group?

Thanks!  And hope this helps,

Alan

P.S.: Group members, please feel free to supply any corrections...
