`The Cloud’ precipitates casual conversation. Not surprising perhaps, as this weather-borne metaphor puts shape to the state-of-the-art in virtualized IT infrastructure. With actual utilization of The Cloud steadily on the uptick however, conversations are taking on a much more pragmatic tone these days …
Because the impact of unmanaged interactive sessions can be significant, the concept of login nodes in Bright Cluster Manager was introduced in Part 1 of this series. Although login nodes address many considerations relating to interactive use, they are designed to do so in a limited way. For example, in Part 1, the following consideration was outlined (emphasis added here):
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.
The last time I participated in Bio-IT World it was May 2005. While Web inventor Sir Tim Berners-Lee keynoted the event opening by sharing his vision for a next-generation Web, those of us in the trenches (aka. the exhibits area) attempted to communicate the value proposition for grid computing - or was it Grid computing, or even Grid Computing ...
Okay, you've logged into a node, installed packages and have gotten it to just the perfect state. Now you want to save the running state of this node back a new Bright Cluster Manager software image. Good plan: it will save you a lot of time moving forward. This article shows how to do that using the Bright Cluster Management Shell (CMSH). Of course this can also be done using the CMGUI, but that's a different "how-to" article.
Bright Cluster Manager takes away the complexity of managing Linux clusters. One such example is how using Bright's intuitve CMGUI you can easily provide read-only access to the cluster. This article shows how to create an x509 certificate based on the read-only authorization profile in five fast and easy steps.
Bright Cluster Manager makes so many tasks fast and easy, so that you can move on to more important priorities. Let's look at managing Power Distribution Units (PDUs).
Bright Cluster Manager enables you to easily manage all the components of your HPC cluster, including PDUs. Adding a PDU is one of the first things you'll want to do after you complete the initial head node installation. Once added, you'll be able to monitor and manage the PDU through Bright. This article shows how to add a PDU using the Bright CMGUI.
Let's get started.
