Fun with CMSH

By Robert Stober | July 23, 2020

Those of you who are familiar with Bright probably know that CMSH is the Cluster Management Shell. The CMSH is one of the two administrative interfaces provided by Bright Cluster Manager, the other being Bright View. Most people start off using Bright View, because it’s easy to use. But in time, most admins learn how to use the CMSH because of its power; it allows them to operate on many nodes simultaneously. Here are a couple of tips that will make your use of CMSH more enjoyable.

Getting Started with Easy8

By Robert Stober | June 25, 2020

When we launched the Bright “Easy8” program and our BEACON user community in November last year, we took the unprecedented step of making Bright Cluster Manager free for clusters up to 8 nodes. This empowered organizations to reap the benefits of our mature commercial cluster management system at no charge.

The WAR against inefficient HPC cluster resource utilization

By Robert Stober | March 27, 2020

To extract the most value from your HPC cluster, you need to ensure that system resources are being properly utilized.  HPC system users are notorious for over-requesting resources for their jobs, resulting in idle or underutilized resources that could otherwise be doing work for other jobs.  While one reason for this can be users hoarding resources to ensure they have what they need, another common reason why users over request resources is that they simply don’t know what resources their jobs will need to complete the job in a specified time.  For administrators to ensure that their precious and expensive cluster resources aren’t being squandered, they need to get actionable details regarding how the resources are being used.  More specifically, they need to know things like which jobs are using which resources, which jobs aren’t using resources that they’ve provisioned and which users are repeatedly hoarding resources unnecessarily, as well as other things.

Multiple Workload Management Clusters with Bright 9.0

By Robert Stober | January 21, 2020

A significant change we’ve seen in the HPC landscape is the need to process data and run workloads at the edge. Last year, Bright delivered Bright Edge, which allows organizations to quickly and easily provision and manage servers at edge locations and enabled them to manage multiple locations as a single cluster. The new year brings with it Bright 9.0, which provides the ability to deploy and manage a workload manager (WLM) instance at each location.

How To Configure Bright Auto-Scaler to Achieve True Convergence of HPC and AI

By Robert Stober | September 17, 2019

Auto-scaling HPC and Kubernetes

Bright CEO Bill Wagner’s recent blog post “The Convergence of HPC and A.I.” pointed out that creating HPC and Kubernetes silos within a shared HPC infrastructure is more like “coexistence than convergence”. The solution I will be highlighting  is Bright Auto-scaler, which automatically resizes HPC and Kubernetes clusters (workload engines) according to workload demand and configured policies. This post describes how to configure Bright Auto-scaler to achieve true convergence of HPC and A.I. through a scenario.

Why pay for a second monitoring solution when you can use Bright?

By Robert Stober | April 19, 2019

One of Bright Cluster Manager’s most popular features is its built-in monitoring system. It is lightweight and efficient, and it works right out of the box. But what people generally don’t know is that they can use Bright to monitor non-Bright nodes; nodes that were neither provisioned by, nor managed by, Bright. The Bright Lightweight CMDaemon can be used to monitor and healthcheck auxiliary servers that support the cluster but aren’t part of it, for example, database servers, authentication servers, and file servers.
