Hermes is a high performance virtual private cloud for faculty and researchers at SUTD. It exists alongside other HPC facilities, such as Titan and the Nvidia DGX-1, to give researchers access to a flexible cloud computing system similar to commercial providers such as Amazon Web Services and Microsoft’s Azure. Hermes runs on top of Apache’s Cloudstack (https://cloudstack.apache.org/), which provides an easy-to-use web interface for launching and managing virtual machines. It is also compatible with popular cloud orchestration tools such as Ansible (https://www.ansible.com/) and Terraform (https://www.terraform.io/).
Hermes provides a total of 384 Intel Xeon 2.4Ghz cores and 6TB of RAM (maximum per virtual machine is 16 cores and 256GB of RAM). Ceph is used as a storage backend, providing 100TB of double-redundant storage space. All nodes are connected with 10GB Ethernet. Researchers can launch one or more virtual machines, using their preferred OS (Ubuntu, CentOS, Windows) and software. Machines can run permanently or can be launched and destroyed on an as-needed basis (for example to run ad-hoc, parallel computations). By default, virtual machines are only accessible from within the SUTD network but a public IP address can be assigned on a case-by-case basis.
