The Cluster is made of some servers and blades organized in 3 racks physically located in the Cluster Room and Datacenter Room in Mancinelli site. The main hardware components where part of the former Labs cluster, new acquisitions and one blade from Mathematics Dept. Datacenter donated from a Research group of DICA.

The Masternode provides:

1. A file system /opt/ohpc/pub/ on local Raid5 storage (up to 2 TB) for applications and process management, shared via NFS on Gigabit network
2. A file system /homes on Dept. high performance Storage (up to 5 TB) for homes and user data shared via NFS on Gigabit network (Morgana nodes have 1 Gb bandwidth guaranteed due to 10Gb Ethernet hardware)
3. Login for users
4. Node provisioning software (installation of new nodes and node rebuild in less than 5 min.)
5. PBSPro master for scheduling and resource management
6. Support for Singularity container technology
7. Infiniband network controller (via software)
8. Application software for compute nodes
9. Monitoring and utility software (Ganglia, Nagios, Hpc website and web interface to PBSPro submission)

The cluster has been installed following the directions of the OpenHPC Project, an open source project backed by Intel and many software and hardware HPC player and supported by a strong developer community. The main reason for this choice is that they committed to support the upgrade of the software platform following the evolution of the single components (OS, compilers, MPI distributions, toolchains components, utility software, hardware support, container technology) and also for their independence from a specific vendor or technology. The installed software is divided in Management and operations software and Application software.
