ARC1 switch-off 31 May 2017

Just in case you missed it: ARC1 is being turned off at the end of May 2017.

Hello everyone,

This is another reminder that the ARC1 service closes permanently on May 31st 2017.

If you have not yet made arrangements to migrate your work over to one of the other clusters or you don’t have an account on one of the other machines you need to do this as a matter of urgency.

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.
