DARWIN account requests

Each Principle Investigator (PI) must have an active UD allocation (Startup, Education or Research) to be able to make any type of account request for DARWIN. If you do not have an active allocation, then you can submit a request with the Data Science Institute (DSI) for DARWIN.

The PI of an allocation can request to add or remove access for a user on their workgroup by submitting a Research Computing High Performance Computing (HPC) Clusters Help Request and click on the green Request Service button and complete the form including DARWIN Account Request in the short description, selecting High Performance Computing as the problem type, and in the description indicate which allocation ('workgroup -q workgroups) and all of the users' full name and email addresses to add or remove. * UD community members: UDelNet ID and full name * Guests: Full name and email address (preferably a university, institution or organization; not personal) </note> If you are a UD community member, your UD allocation username and password are the same as your UDelNet ID and password. You may change your UDelNet ID or password on the UD network page, but it is only synced at noon and midnight daily on DARWIN. If you are not a UD community member, IT will create a username having the form hpcguest«uid», and an initial password sent to you as a PDF when your account is created. The «uid» is based on a unique, 4-digit numerical identifier IT assigns to you. You can change your password via UD IT HPC page by clicking on the login button at the top of the page and enter your hpcguest«uid» and current password. The new password will immediately take effect on HPC systems. Your password should always comply with UD's password recommendations. ^Command ^Function ^ | hpc-user-info -a «username» |Display info about a user | | hpc-user-info -h |Display complete syntax | For example, <code bash> [traine@login01.darwin ~]$ hpc-user-info -a traine full-name = Student Training last-name = Student Training home-directory = /home/1201 email-address = traine@udel.edu </code> ==== UD allocation groups ==== The allocation groups of which you are a member determine which computing nodes, job queues, and storage resources you may use. Each group has a unique descriptive group name (gname). There are two categories of group names: class and workgroup. The class category: All users belong to the group named everyone. Members of the UD community also belong to the group named ud-user. Non-UD users are members of the group named hpc-guests. Other group names currently include facstaff and students. The workgroup category: Each workgroup has a unique group name (e.g., nanotech or the Principal Investigator's (PI) UDelnetID) for each allocation. The PI and users are members of that allocation group (workgroup). To see the usernames of all members of the workgroup, type the hpc-group-info -a «allocation_workgroup» command. Use the command groups to see all of your groups. The example below is for user traine <code bash> $ groups everyone ud-users students it_css </code> For example, the command below will display the complete information about the workgroup it_css and its members. <code bash> $ hpc-group-info -a it_css name = it_css gid-number = 1002 description = John Huffman member = traine; Student Training; traine@UDel.Edu member = trainf; Faculty Training; trainf@UDel.Edu </code> The output of this command represents (description = PI), along with every member in the workgroup and their account information (Username, Full Name, Email Address). ===== ACCESS (XSEDE) allocations ===== For ACCESS allocations on DARWIN, a PI may use the ACCESS Allocations portal to add or remove accounts for an active allocation on DARWIN as long as the person you want to add has an ACCESS user portal account. If the person doesn’t have an ACCESS portal user account, then they need to visit the ACCESS User Registration to create one. The person will need to share their ACCESS user portal account with the PI to be added. Please keep in mind it may take up to 10 business days to process an account request on DARWIN for ACCESS users. ==== ACCESS (XSEDE) allocation accounts ==== An ACCESS user on DARWIN will be assigned a username having the form xsedeuuid. The uid is based on a unique, 4-digit numerical identifier assigned to you. An email with the subject "[darwin-users] New DARWIN ACCESS (XSEDE) account information" will be sent to the ACCESS user once their account is ready on DARWIN. Please keep in mind it may take up to 10 business days to process an account request on DARWIN for ACCESS users. Passwords are not set for ACCESS accounts on DARWIN, so you must set a password using the password reset web application at https://idp.hpc.udel.edu/access-password-reset/. The application starts by directing the client to the CILogon authentication system where the "ACCESS CI (XSEDE)" provider should be selected. If successful (and the client has an account on DARWIN), the application next asks for an email address to which a verification email should be sent; the form is pre-populated with the email address on-record on DARWIN for the client's account. The client has 15 minutes to follow the link in that email message to choose a new password. The form displays information regarding the desired length and qualifications of a valid password. If the new password is acceptable, the client's DARWIN password is set and SSH access via password should become available immediately.

ACCESS users on DARWIN can use the password reset web application to reset a forgotten password, too.
