Requesting credits for the free standard service
Please email email@example.com with a conservative estimate of the number of credits or CPU hours you require to run your jobs, along with a brief description of the research project that ARC will be supporting. One of the team will respond promptly and add the credits to your ARC project.
Purchasing credits for the priority services
If you would like to purchase credits with funds from a research grant please contact us first to discuss your requirements.
Once this is done and you know how many credits to purchase, please complete the Internal Trade Recharge Form using either the FEC or non-FEC options and sent by email to firstname.lastname@example.org or in hard copy to Advanced Research Computing, IT Services, 13 Banbury Road. Alternatively, payment can be made via Purchase Order on request.
Once the payment is received, you are notified that the credits purchased were added to the project.
Cost of Credits
Pricing is reviewed annually. Compute credits bought do not expire.
The Full Economic Cost (FEC) of credits for CPU compute time is £0.01 or 1p per core hour (e.g. 10,000 core hours will cost £100). For GPU accounting this CPU core hour charge is increased to £0.08 or 8p, with each additional GPU requested costing an additional £0.08 per CPU core hour used.
You should use this cost in any grant applications, this is based on ARC being an SRF type of facility.
The cost of additional storage allocation above the standard 5TB per project allocation is £250 per TB per year. This cost is on top of that of compute time.
If you require costings for EU grant applications please contact us.
Purchasing credits with grants and other sources
Purchasing credits with an FEC Grant
Typically, this will be from a specific Directly Allocated Facility cost from a Research Council or similar type of grant under Full Economic Costs (FEC). For FEC grant you will need to provide the following:
- Cost centre and account string you wish to be debited
- Line description for the journal
- PI (budget holder) signature
- Departmental Adminstrator's signature
Non-FEC Projects and other sources
In the case of non-FEC grants you will need to provide the following on the form:
- Project code
- Award number
- Expenditure type
FP7 EU Funding (Directly Incurred headings)
Owing to audit requirements we have to handle such funding in a different way. Essentially we have to invoice the user in arrears for actual, auditable usage. We can do this but it's best to get in contact first to discuss.
We welcome external users; please contact us to discuss your requirements.
