The Bright Cluster Manager CMGUI makes tasks intuitively easy. This article shows how you can view and control workload manager jobs using the Bright CMGUI. I am using an OGS (SGE) job to provide examples, but Bright works the same way with all Bright's supported workload managers: PBS Professional, Slurm, Univa Grid Engine, LSF, openlava, TORQUE/Moab, TORQUE/Maui.
This article describes basic Slurm usage for Linux clusters. Brief "how-to" topics include, in this order:
- A simple Slurm job script
- Submit the job
- List jobs
- Get job details
- Suspend a job (root only)
- Resume a job (root only)
- Kill a job
- Hold a job
- Release a job
- List partitions
- Submit a job that's dependant on a prerequisite job being completed
Bright Cluster Manager does not include the VNC Server package by default but you can easily add it. This article shows how to do it in a few quick and easy steps.
The Bright Cluster Manager installer allows you to customize the disk partition layout on the head node as well as the compute nodes. While the layout of compute nodes can be changed after installation, the head node partitioning layout cannot. So it's important to think about how you want to partition the disks on the head node before installation. The Bright installer provides a built-in editor you can use to customize the disk layout. But you can also do this outside of the Bright installer. This article describes how to edit the master disk layout outside of the Bright installer.
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.
This article shows how to run the Intel MPI Benchmark (IMB) on a Bright cluster. In this example we will run the benchmark over low latency 10GbE interfaces.
Bright Cluster Manager makes so many tasks fast and easy to complete. This article shows how to list, show, and modify Grid Engine parallel environments.
Parallel environments are parallel programming and runtime environments that facilitate the execution of shared memory or distributed memory parallel applications.
