AWS parallelcluster documentation change

Service: parallelcluster · 2026-06-04 · Documentation low

File: parallelcluster/latest/ug/LoginNodes-v3.md

Summary

Updated documentation to replace 'NICE DCV' with 'Amazon DCV' terminology throughout, fixed minor grammatical errors ('Specifies single script' to 'Specifies a single script'), and standardized internet address capitalization.

Security assessment

Changes involve branding updates (NICE DCV to Amazon DCV) and grammatical fixes without altering security configurations. The existing security guidance about IP restrictions (AllowedIps) and certificate usage remains unchanged.
