DUCC-Un-managed Reservation??

["reshu.agarwal" <re...@orkash.com>]

Hi,

I am bit confused. Why we need un-managed reservation? Suppose we give 
5GB Memory size to this reservation. Can this RAM be consumed by any 
process if required?

In my scenario,  when all RAMs of Nodes was consumed by JOBs, all 
processes went in waiting state. I need some reservation of RAMs for 
this so that it can not be consumed by shares for Job Processes but if 
required internally it could be used.

Can un-managed reservation be used for this?

Thanks in advanced.

Reshu.

Basically yes. See more info about "Rogue Process" in the duccbook.

Any idea why all process went into waiting state? Did the job details page
show that these JPs were assigned work items?
