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.

For account applications, see here:

Extra HPC provision on Monsoon (NEXCS)

Hi All,
the details are here:

Project resource

Requests for NERC project resource should be made through the regular NERC process – in the early-usage stage (April 2017 – July 2017), access will be open.

Machine access

NEXCS has the same 2-factor security model as does Monsoon2; a fob is required to access a bastion machine (the lander) with subsequent ssh to the xcs. NEXCS maintains accounting groups (projects) to which users are assigned after receipt of a security fob.

Current Monsoon2 users need only be added to an appropriate NEXCS group to use the resource.

Contact NCAS-CMS to request access to NEXCS and/or access to specific projects.

UM Users Monsoon Switch-over has happened

We had plenty of warning.
The umsystems team have consolidated the “lander” user id of those of us with Met Office internal unix IDs. On the new Monsoon (xcs-c) those userids will have no data available unless it was transferred from the previous userid. That includes all data in the /projects/project/useridB working directories (DATADIR). The earlier userid is referred to as UseridB and the consolidated userid is UseridC.
I had to set up a blank key on XCM to add to the authorized_keys on XCSC to allow password-less transfer of data.

For the last week I have transferred data from XCM _to_ XCSC by pushing with:
scp -p A useridC@xcslc0:A

Now I find I should have also made a reverse key (oops) as I can only log into my earlier user id (Monsoon terminology useridB) with a password. Which I do not know.

This link is to instructions on the collaboration Twiki which requires a separate login (which hopefully you already know).

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.

Software Sustainability Institute Collaborations Workshop – Hosted here at Leeds!

From March 27th to 29th 2017, the Software Sustainability Institute’s Collaborations Workshop 2017 (CW17) will be here at the University of Leeds.

The workshop is now open for registration at It will focus on hot topics, sharing of best practice and tools and approaches in research software.

This year’s topic is Internet of Things (IoT) and Open Data: implications for research.

CW17 is an ‘unconference’ event, which means that you get to control the direction of the workshop by voting for the topics we discuss. The
workshop’s themes will run through the schedule. They will be discussed in keynotes, lightning talks, and demos, and debated during discussion

Read the SSI blog post for more reasons why you should attend CW17 (

We look forward to seeing you there!

We would greatly appreciate if you forwarded this email to all your relevant contacts.

Thank you very much in advance.

Martin Callaghan, ARC, Leeds.

[Event] Research Data Leeds 26th October

Support Icon

I have been informed of an event that might be of interest to SEE.
The event will be held on the newly refurbished Research Hub on Level 13 of the Edward Boyle Library. Come and have a look!

There will be short talks showcasing some of the data we have in the data repository and a chance to discuss what you’d like to see in terms of the research data service and research data oriented events and training.

Come and scribble your thoughts on our white board wall and think about how you and your colleagues might make use of the Research Hub.

Drinks and biscuits provided.

Please register on Eventbrite so we know how many biscuits to get.

ARCHER information about Intel Knights Landing (KNL)

The new generation Intel Xeon Phi is more widely known as “KNL”. The ARCHER service are commissioning a test and development small system. It is expected to be available for early adopters in late October with a month of FoC use with a subsequent step up to an AU charge.

More details can be found on this page in the webinar “Using KNL on ARCHER” (12th October 2016)

Archer Training Information

The slides are probably good enough information on their own but there is a video on the Archer Youtube channel.
