PP-587: Have only one mom report the compute node information to the server


#1

This message is to inform developers that there is a new design document available for review:

Please provide your comments in this community forum.

Thanks.

Since this features is Cray X* specific, I suggest adding “Cray” or “Cray X-series” in the Jira ticket summary. (I was initially confused by the summary as this applying and speeding up all systems with lots of nodes; once I read the full paragraph in the description I finally got that this feature only applies to Cray X* systems.)


#3

Thanks @billnitzberg I have put that information in the “Environment” field in the Jira ticket. And I have also added a sentence at the beginning of the overview section.


#4

The EDD looks good to me.


#5

What happens if the vnode_pool attribute is set to different values within the same Cray system?


#6

Don’t do that! Basically the benefit of setting a vnode_pool to have only one mom report the compute nodes would be negated and PBS’s behavior would be undefined.


#7

OK then, I think the EDD looks good


#8

I made changes to the design:

  1. I numbered the interface changes
  2. I added interfaces 8 and 9

#9

I added a line to state that vnode_pool will only be displayed when it has been set.
This isn’t a change in behavior. I’m making the expected behavior clearer.
Please review.

@lisa-altair, the EDD looks good with the new changes.
