NOTE: UAI is deprecated in CSM 1.5.2 and will be removed in CSM 1.6.
Using a default UAI class is optional but recommended for any site using the legacy UAI management mode that wants to have some control over UAIs created by users. UAI classes used for this purpose need to have certain minimum configuration in them:
image_id
field set to identify the image used to construct UAIsvolume_list
field set to the list of volumes to mount in UAIspublic_ip
field set to true
uai_compute_network
flag set to true
(if workload management will be used)default
flag set to true
to make this the default UAI classTo make UAIs useful, there is a minimum set of volumes that should be defined in the UAS configuration:
/etc/localtime
for default timezone information/lus
In addition to this, there may be volumes defined to support a workload manager (Slurm or PBS Professional) or the Cray Programming Environment (PE) or other packages the full extent of these volumes is outside the scope of this document, but whatever list of these other volumes is needed to get a suitable End-User UAI should be included in the default UAI class configuration.
The UAI Classes section has more information on what goes in End-User UAI classes and, specifically, the Non-Brokered End-User UAI classes used for Legacy mode.
