This repository provides the utilities necessary for quickly building an OpenHPC test cluster using VirtualBox VMs and Vagrant.
Install the following software.
To build a cluster of $N nodes, where 1 <= $N <= 10, run:
make NCOMPUTES=$N
A directory named cluster will be built. Change into the cluster directory
before running subsequent commands.
To start the SMS, run:
vagrant up
Provisioning the first time will take approximately ten minutes. Once the SMS is running, you can SSH into it:
vagrant ssh
If you are doing Slurm development, you can run the following script to start up Slurm and establish some default accounting settings.
/vagrant/slurm-setup.sh
Compute nodes are named c1, c2, ..., c$N. For any given compute node, say
c$i, you can start it with:
vagrant up c$i
When booting compute nodes, Vagrant will be unable to communicate with them as they only have an internal network. Ignore the error message Vagrant spits out after 10 seconds of booting. The SMS will provision the compute nodes, which will take approximately two minutes.
The ordinary Vagrant halt, destroy, and status commands may be useful as
well.
