ARCHER work allocation request

Reported by: Leighton_Regayre Owned by: um_support
Component: UM Model Keywords: ARCHER allocation work n02
Cc: Platform: ARCHER
UM Version: 11.1

Description

Hello,

In order to make a large ensemble of simulations on ARCHER over the next few weeks, I need to draw on assistance from project colleagues Lucia Deaconu and Chris Symonds.

Could you please increase their ARCHER /work/n02 allocations to make this possible? They'll each need around 58Tb of additional space if possible. Everything else is in place to allow their contribution to making this ensemble.

Lucia's and Chris's ARCHER usernames are:
luciad
chmcsy

Both Lucia and Chris are aware of this ticket and request.

Thanks very much,

Leighton

You have an allocation of 60TB - if you fill that, n02 will have ~30TB spare, that's assuming that no other user writes anything to /work. I can't allocate an additional 116TB - since that much is not available. I can allocate some of the possibly spare 30TB. In doing so, there is still a risk that /work fills up and all jobs stop running.

Hi Grenville,

Thanks for the explanation. I thought my request might be optimistic. The limiting factor for us is the ARCHER queue. As an alternative, could we reduce my allocation to 30Tb (freeing 30Tb) and then increase allocations for Lucia and Chris by 20-25Tb each (using the 30Tb from my allocation and 10-20 of the remaining "spare" 30Tb)?
