-  * contact the principle stakeholder for the //investing-entity// on Mills and provide the sponsored users' full name and email address.
+The cluster's compute nodes are organizationally identified by UD research
+group names. A //stakeholder// is a UD researcher who contributed financially to a node's purchase. An
+//investing-entity// consists of the stakeholders who combined funds to purchase a particular
+compute node or set of nodes. Each investing-entity has a //principal stakeholder// who is the
+administrative point of contact for its compute nodes.

+There are two types of cluster accounts: //stakeholders// and //sponsored users//. Sponsored users

+For each investing-entity, the principal stakeholder is responsible for establishing and enforcing
+group-use policies for his/her sponsored users.

+</note>
+If you are a UD community member, your cluster username and password are the same as your UDelNet ID
+and password. You may change your UDelNet ID or password on the [[http://www.udel.edu/network|UD network page]], but it is only synced at noon and midnight daily.
+If you are not a UD community member, IT will create a username having the form //hpcguest//<<//uid//>>, and
+an initial password for you. It is based on the unique, 4-digit numerical identifier IT assigns to you. You can [[https://www.hpc.udel.edu/user/password.php|change your password]] via [[http://www.hpc.udel.edu|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 [[http://www1.udel.edu/security/bestpractices/passwords.html|password
+recommendations]].

+===== Cluster groups =====
+The cluster 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 //investing-entity//.
+**//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//, //students//, and
+//stakeholders//.
+**//The investing-entity category//**: Each investing-entity has a unique group name (e.g., //nanotech//
+or the principal stakeholder's username) also referred to as [[abstract:mills:app_dev:compute_env#using-workgroup-and-directories|workgroup]]. The investing-entity's stakeholders and its sponsored
+users are members of that cluster group. To see the usernames of all members of an
+investing-entity's group, type the ''getent group'' <<//investing_entity//>> command.
+For example, the command below will display the usernames of the ''it_css'' members.
+<code bash>getent group it_css</code>
+Together, ''gentent group'' and ''hpc-user-info -a'' let you determine the identities of a group's members.
