Fair Use Policy


Any researcher in any location may create an account on the CIPRES Science Gateway and submit jobs on XSEDE resources (XSEDE is a new name for TeraGrid). Users receive 1,000 cpu hours at no cost, but must purchase a subscription to receive more hours. It is a violation of our Fair Use Policy to create multiple accounts to circumvent these limits. Users who engage in this practice will have submissions from their accounts disabled.

Individuals at US academic and non-profit institutions, and those with collaborators in the US who have purchased 50,000 cpu hours from CIPRES can request personal XSEDE allocations. One can quickly receive an additional allocation of 50,000 CPU hours at no additional cost. There is no upper limit to the number of CPU hours that can be requested, although awards above 50,000 are made through a quarterly allocation process, and are more competitive. Users who receive an XSEDE allocation award can run jobs through the CIPRES Science Gateway just as other users do. Their usage is charged to their individual user account until the allocation 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 at academic and non-profit institutions outside the US who do not qualify for allocations from the XRAC because they are not at a US institution and do not have a US collaborator can purchase subscriptions of up to 200,000 cpu hours each year.
