DARWIN account requests

For all UD allocations, the Principle Investigator (PI) of their allocation(s) may add or remove an account on DARWIN 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 How to use it? for the type of information you are looking for, and indicate which allocation (workgroup -q workgroups) and all of the users' full name and email addresses (UD community members and/or Guests) to add or remove in the description.

The cluster's resources are organizationally identified by node types available to cluster allocation workgroups. A workgroup is assigned after an allocation has been submitted by a PI and approved based on the node type resources requested. Each PI is the administrative point of contact for its workgroup.

For each workgroup, the PI is responsible for establishing and enforcing group-use policies for his/her workgroup users.

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 My UD Settings page, but it is only synced at 12:15AM EST daily on DARWIN, so basically the next day. In the meantime, you may continue to use the old password on DARWIN until the update occurs.

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.

For example,

[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

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 workgroup -q workgroups to see all of your workgroups. The example below is for user traine

$ workgroup -q workgroups
1002 it_css

For example, the command below will display the complete information about the workgroup it_css and its members.

$ 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

The output of this command represents (description = PI), along with every member in the workgroup and their account information (Username, Full Name, Email Address).

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.

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 must be selected (as shown in the figure above). 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.

For example,

$ hpc-user-info -a xsedeu1201
full-name = Student Training
last-name = Student Training
home-directory = /home/1201
email-address = traine@udel.edu
clusters = DARWIN

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.

The workgroup category: Each workgroup has a unique group name (e.g., xg-tra180011) assigned 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 workgroup -q workgroups to see all of your workgroups. The example below is for user xsedeu1201

$ workgroup -q workgroups
 1120  xg-tra180011

For example, the command below will display the complete information about the workgroup xg-tra180011 and its members.

$ hpc-group-info -a xg-tra180011
name = xg-tra180011
gid-number = 1120
description = Student Training
member = xsedeu1201; Student Training; traine@udel.edu

The output of this command represents (description = PI), along with every member in the workgroup and their account information (Username, Full Name, Email Address).
