estimated cost and run time of running regional UM on ARCHER

Reported by: anmcr Owned by: um_support
Component: UM Mesoscale Keywords: MAUs, regional model, run tim
Cc: Platform: ARCHER
UM Version: 8.2



Could you please give me an estimate of the cost of running the mesoscale model on ARCHER, and also some estimate of run time? The resolution I am thinking of would be 5 km, but I should be able to get an idea for this by scaling previous estimates.

I would really appreciate if this could be done ASAP as it is required for a grant proposal with a deadline of tomorrow.

Many thanks,

Hi Andrew,

A 4km model running over an north Africa domain (SWAMMA) used 12.4 MAU in a 153 model day run producing 52 TB of output. The Africa domain was 1380x1020. This was UM 8.2 on ARCHER. It ran at 10 model days per day.

So if you scale this by your domain size and the number of model days you want you should get a reasonable ball park.

It of course depends on the science you have switched on and the STASH output you need. If you had time you could do a short pilot run with an actual model to get a better estimate.

Dear Willie,

Thanks for the information and for providing it so quickly. It was exactly what I required.

You can now close this ticket.

Best wishes,
