Fair Use Policy


Any researcher may create an account on the CIPRES Science Gateway and submit jobs on XSEDE resources. Individual users may access 1,000 CPU hours/year of the community CIPRES Science Gateway allocation at no charge. Users may access more compute time by purchasing a paid subscription via credit card or via purchase order. Any user may purchase up to 200,000 cpu hours in a given year. Users within the US who have purchased at least 50,000 cpu hours may access a personal XSEDE allocation using CIPRES at no additional cost. In other words, purchasing a level 4 subscription entitles the user to access any existing XSEDE allocation at no additional cost.

Individuals at US academic and non-profit institutions, and those with collaborators in the US can request XSEDE allocations. There is no upper limit to the number of CPU hours that can be requested, but requests above 50,000 cpu hours are more competitive, and are awarded quarterly. Requests of 50,000 and below are reviewed on an ad hoc basis, and are awarded quickly. Users who subscribe at level 4 can run jobs through the CIPRES Science Gateway by charging to a personal allocation. Their usage will be charged to their individual allocation until it is exhausted. At that time the user can submit a request for supplemental time, or submit a completely new request. Our group will provide support and advice on submitting applications to the TRAC. Let us know if you need help.

For a step-by-step guide to requesting an allocation, see here.

Why do I have to do this? The logic for the request is simple: you are requesting access to large and costly resources funded by the US National Science Foundation. These resources are always over-requested. The application process insures that research supported by the CSG and XSEDE is peer reviewed, and uses resources funded by US taxpayers well.

Individuals who do not qualify for allocations from the XRAC because they are not at a US institution and do not have a US collaborator may purchase up to 200,000 cpu hours per year.

If you have questions, please let us know.
