Can't use c8g ARM Graviton4 instances on 3.13.2 using UI

[rems0]

Hi all,

Required Info:

• AWS ParallelCluster version:
  3.13.2

Bug description and how to reproduce:
When using the UI to create a new cluster, c8g.* instance types don't get listed in the compute resource drop down menu. Tried at Ohio - us-east-2 - where c8g.* instances are available.
c7g.* get listed though, but we want to use the newer c8g.* ones.

Is this a bug or am I missing something?

Kind regards,
Richard

Hi @rems0 ,

This is a known limitation for PCUI (code). You can modify the cluster configuration at the end of the wizard to use c8g.

Thank you,
Hanwen
