Step 1: Request an allocation

The ALCF offers several allocation programs through which users can access our systems:

• New users should consider our Director’s Discretionary program.
• Experienced users will be interested in the INCITE, ALCC, and ALCF Data Science programs.

Step 2: Request an account

Users must establish an account on ALCF systems before they can access ALCF systems.

You can request an ALCF account on our accounts page.

Step 3: Connect and login

Your CRYPTOCard must be activated before its first usage to connect to ALCF systems. Call the ALCF Service Desk (630-252-3111 or 866-508-9181) to verify your identity and activate the token.

Login Instructions
