Welcome to TrinityX!
TrinityX is the new generation of ClusterVision's open-source HPC platform. It is designed from the ground up to provide all services required in a modern HPC system, and to allow full customization of the installation. Also it includes optional modules for specific needs, such as an OpenStack cloud and Docker on the compute nodes.
The full documentation is available in the
doc subdirectory. See the instructions how to build it below.
In standard configuration TrinityX provides the following services to the cluster:
- Luna, our default super-efficient node provisioner https://github.com/clustervision/luna
- and more
It will also set up:
- NFS-shared home and application directories
- environment modules
- and more
Steps to install TrinityX
Install CentOS Minimal on your controller(s)
Configure network interfaces that will be used in the cluster, e.g public, provisioning and MPI networks
Configure passwordless authentication to the controller itself or/and for both controllers in the HA case
Setup luna repository:
# curl https://updates.clustervision.com/luna/1.2/centos/luna-1.2.repo > /etc/yum.repos.d/luna-1.2.repo
# yum install git ansible luna-ansible
Clone TrinityX repository into your working directory and go to the site directory:
# git clone http://github.com/clustervision/trinityx # cd trinityX/site
Based on whether you're installing a single-controller or a high-availability (HA) setup, you might want to update the configuration files:
Note: In the case of an HA setup you will most probably need to change the default name of the shared block device set by
You might also want to check if the default firewall parameters apply to your situation in the firewalld role in
firewalld_public_interfaces: - eth2 firewalld_trusted_interfaces: - eth0 - eth1
OndrejHome.pcs-modules-2from the ansible galaxy:
# ansible-galaxy install OndrejHome.pcs-modules-2
hostsfile to allow ansible to address controllers.
Example for non-HA setup:
[controllers] controller ansible_host=10.141.255.254
Example for HA setup:
[controllers] controller1 ansible_host=10.141.255.254 controller2 ansible_host=10.141.255.253
Start TrinityX installation:
# ansible-playbook controller.yml
Note: If errors are encoutered during the installation process, analyze the error(s) in the output and try to fix it then re-run the installer.
Note: By default, the installation logs will be available at
Create a default OS image:
# ansible-playbook compute.yml
Now you have your controller(s) installed and the default OS image created!
Customizing your installation
Now, if you want to tailor TrinityX to your needs, you can modify the ansible playbooks and variable files.
Descriptions to configuration options are given inside
group_vars/*. Options that might be changed include:
- Controller's hostnames and IP addresses
- Shared storage backing device
- DHCP dynamic range
- Firewall settings
You can also choose which components to exclude from the installation by modifying the
