ARC1 to be switched off in May 2017

Advanced Research Computing (ARC) have announce that ARC1 is in its final days and will be switcehd of after 31st May 2017.

That is only 13 weeks away from 21st Feb posting)… Is that long enough for you to ensure your codes will work?

You should consider migrating your cods, workflows and data to another local HPC system such as (ARC2, ARC3, MARC1 or the N8 machines: Polaris or HERC1)

You can ask ARC about the arrangements at

Another thing to note is that the system is approx 8 years old and any failed parts are being replaced with similar age parts and so mean-time-between-failure is shortening. I believe the system availability has been around 60% over the last 12 months.

NERC HPC application for resource deadline approaching (28th Feb 2017)

The deadline for submitting an application to use ARCHER for 2017/2018 is early next week. Our concern is the statement on the NERC site
” Any applications received after this date will only be considered by the HPC Steering Committee if time permits. ”

See :

For example there are two categories ARCHER uses
(i) running under n02-chem (which is managed by Grenville Lister) and used mainly by aerosol and chemical composition groups.
(ii) running under a project account related to a project or proposal.

A) For a project similar to those within n02-chem AU budgets and less than 50 MAU per year:
They can run under n02-chem and they just have to do a brief outline of their work to Grenville.
B) If the user uses > 50 MAU per year, they need to fill out a new project form, and apply for a project code. This is fairly laborious. If you did this last year and want the project to continue you need to fill in a continuation form.

If you want some guidance on calculating the AU budget prediction then let CEMAC know and we can talk you through that section.
