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
- SLURM or OpenPBS
- Telegraf, InfluxDB and Grafana
- Infrastructure services such as NTP, DNS, DHCP
- and more
It will also set up:
- NFS-shared home and application directories
- OpenHPC applications and libraries
- environment modules
- and more
Steps to install TrinityX
Install CentOS Minimal on your controller(s). It is recommended to put
/var/lib/influxdbon it's own filesystem.
Configure network interfaces that will be used in the cluster, e.g public, provisioning and MPI networks on the controller(s).
Configure passwordless authentication to the controller itself or/and for both controllers in the HA case.
Clone TrinityX repository into your working directory. Then run
`prepare.sh`to install all the prerequisites.
# git clone http://github.com/clustervision/trinityX # cd trinityX # bash prepare.sh
Based on whether you're installing a single-controller or a high-availability (HA) setup, the contents may differ. Please view the contents of the file on the directives that may need modification(s):: # cd group_vars # cp all.yml.example all.yml
You might also want to check if the default firewall parameters in the same file apply to your situation:
firewalld_public_interfaces: [eth0] firewalld_trusted_interfaces: [eth1] firewalld_public_tcp_ports: [22, 443]
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
hostsfile to allow ansible to address controllers. # cp hosts.example hosts
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 ``/var/log/trinity.log``
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
The OpenHPC project provides a framework for building, managing and maintain HPC clusters. This project provides packages for most popular scientific and HPC applications. TrinityX can integrate this effort into it's ecosystem. In order to enable this integration set the flag
A pre-built PDF is provided in the main directory. To build the full set of the documentation included with TrinityX:
# yum install git
Clone TrinityX repository into your working directory and go to the directory containing the documentation:
# git clone http://github.com/clustervision/trinityx # cd trinityX/doc
pip, e.g. from EPEL repository:
# yum install python3-pip.noarch
# pip3.4 install sphinx Rinohtype
Build the PDF version of the TrinityX guides:
# sphinx-build -b rinoh . _build/
If everything goes well, the documentation will be saved as
