RE: End-of-reservation resource allocation

[Dmitri Chebotarov <dc...@gmu.edu>]

Thank you. 
Could a PML module return "No Image"/4 value, which would shutdown computer? 

Thanks.

Hi Dmitri,

One change that might help is to make sure you using the Predictive
Loading Module 1. It sounds like yours is currently is set to
Predictive Loading Module 0. Predictive Loading Module 1 looks at
historical reservation data and selects a popular image over some time
period X that is not loaded&available. Time period X change vary based
on how busy your system is.

You can change the Predictive Loading Module under Management
Node->Edit Management Node Information->Edit the desired management
node.

I think there are a couple of jira issue that relates to putting a
reload weight on a image which would be used to determine from a admin
if an image should be reloaded or not. Also another jira issue on
developing a power management profile which would could lead
hibernating/unloading & turning off nodes.

Hope this helps,
Aaron

Since the "No Image"/4 value never gets selected by end-users, the
current PLM code would never return it.

Ideally, I think we would want to set a reload policy:

My thoughts are that the reload policy might have the options to:
* always power down after machine is used
* only power down a vm if system is below a certain usage level
* load, but hibernate/suspend the vm or node
* load images based on a image priority or image weight (i.e. a weight
of 0, would never get reloaded)

Thoughts?
