Whether it’s force of habit, or from actual need, users of HPC environments crave interactivity. Because the impact of unmanaged interactive sessions can be significant, there exists the potential for concern. Is it possible to meet users’ need for interactivity while managing the potential for impact? In this first part of a two-part series on managing interactive impact, attention focuses on the introduction of login nodes to a cluster managed by Bright Cluster Manager. The second part in this series will focus on use of workload managers as a complementary means for managing the interactive impact on the compute nodes of a cluster.
Bright Cluster Manager makes so many tasks very easy to perform. This article shows how to configure user authentication against an external NIS server in Bright Cluster Manager. You can accomplish this task in two straightforward steps:
1) Configure the head node
2) Configure the compute nodes
Let's do it.
