How do I get started using XSEDE?

To get started using computing, visualization, and storage resources, and advanced support services, on the Extreme Science and Engineering Discovery Environment (XSEDE), a researcher may apply for an XSEDE allocation or request to be added to an existing one:

• To apply for an allocation, see How do I apply for a new XSEDE allocation? For eligibility requirements, see Who is eligible to apply for an XSEDE allocation?
  
  
• A principal investigator (PI), co-PI, or an Allocation Manager can add users to an existing allocation via the XSEDE User Portal; see For an active XSEDE allocation, how do I add or remove users?.

Once your allocation request is approved, you can use Single Sign-On (SSO) via the XSEDE User Portal to log into all resources on which you have an account. For help, email  help@xsede.org .

Note: If your allocation includes time on a resource at the National Institute of Computational Sciences (NICS), you won't be able to access the resource using SSO until you activate your NICS account. Additionally, access to Nautilus (NICS) requires the use of an RSA One Time Password (OTP) token, which you will receive in the mail after you have activated your account and verified your user information.

Note: If your allocation includes time on a resource at the Texas Advanced Computing Center (TACC), you won't be able to use SSO until you have activated your TACC account. TACC will email you a welcome message that includes a link to the TACC User Portal and instructions for activating your account.

If you prefer to use SSH to access your XSEDE services, you can use Single Sign-On (SSO) once via the XSEDE User Portal to install your public key on those services.

Alternatively, you can request a password from any Service Provider (SP) that allows site passwords.
