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.
This article describes how to configure jumbo frames in Bright Cluster Manager using the Cluster Management Shell (CMSH). Jumbo frames are enabled by changing the MTU (maximum Transmission Unit) on all the relevant switches and network interfaces. Bright makes it easy.
Bright Cluster Manager makes so many HPC cluster management tasks easy to do. This week's Tech Tip shows how to quickly clone a network using the Bright cluster management shell, or CMSH. The CMSH is the command-line interface to the Cluster Management Daemon (CMDaemon) in Bright Cluster Manager. Through the cluster management shell, an administrator has full control over the cluster.
