HPC & Cloud Infrastructure

The ACG offers a diverse set of systems for meeting HPC, Cloud, Storage and Visualization needs.

HPC Cluster

Cloud Computing System

The cloud computing system provides virtual machine services.

Prototype Secure cloud for hosting VMs to work with Sensitive/Compliant data

HPC & Cloud Storage

Our primary storage for HPC and Cloud is a Ceph system comprised of:

Our secondary and backup storage systems are based on ZFS totaling 1.6 PB of storage

As usage on the system grows, so will the system.

Visualization Systems

ACG operates two visualization systems that consist of dual-socket motherboards containing Intel Haswell processers and 256GB of RAM.

Each visualization system is equipped with an nVidia Quadro K4200 video card and is connected to HPC storage by Infiniband.

The systems run VirtualGL software and VNC to allow for VNC connections to render graphics using the servers GPU rather than sending OpenGL calls across the network to be rendered on the VNC client machine. This provides extremely fast 3D visualization with only minimal hardware requirements for the VNC client.

More packages will be installed soon. The address is: and current users of Marconi can access this system with their same credentials.


All Systems are connected with FDR (40 Gbps) and HDR (100/200 Gbps) Infiniband.
