The principal purpose of the Research Councils in funding the HPCx service is to provide a system with capabilities which are unmatched by computing services at the University or department level. Part of the mission of HPCx is to encourage users to broaden their computational work to take full advantage of these capabilities. Courses, technical documentation and direct assistance from the HPCx team are offered to help users in scaling their codes ro run efficiently in large numbers of processors.
The capability incentives scheme is an encouragement to users to broaden their computational science in this way. Under this scheme, codes which scale well are run at a discount — that is, users are not charged the entire cost in AUs of running them. The Capability Incentives policy statement shows that codes are awarded "Seals of Approval" at three levels, depending on how well they scale.
If you have a code which you feel scales to the standard
described in the
policy statement for the scheme, the first step is to
send a query to the helpdesk
making your claim.
This will be investigated by a member of the HPCx team, in consultation with you. If the code measures up, the Seal of Approval will be registered in the HPCx database, and a token for it will be created. The codes and tokens currently registered are shown below.
When you use a code with a Seal of Approval, you include the token in your jobscript, as explained below. When the accounting for you job is done, the software recognises the token, and discounts the number of AUs taken from your budget.
In response to a number of questions, here is a table showing the size of the discount for differing numbers of processors and approval levels.
Minimum Number of Processors Level 256 512 1024 Bronze 5% 5% 5% Silver 5% 15% 15% Gold 5% 15% 30%
Each token grants a Seal of Approval for a particular project to use a
particular code. If the code you wish to use has a Seal of Approval,
but no token for your project, please get in touch with the helpdesk

Find the appropriate token for your code and project in the table above. If there is no token allowing your
project to get a discount with the code you wish to use, please get in
touch with the helpdesk (
that if there is, for example, a gold Seal of Approval, you can still
run the code using less than 1024 processors — you will just get
a lower rate of discount.
Insert the token into the
job_name line of your
job script. For example:
#@ job_name = #abcdef-ghijk#job123
abcdef-ghijkis the token and
job123is the usual name of your job. The
#characters must be there.
Then submit your job as usual. The discounting will be done by the accounting software after your job has run.
