HPC

The creation of a high performance computer facility is essential to the success of the project. Research in Crete is currently inhibited by the inability to perform computations on problems that demand serious computer power, such as those that demand bases with large number of states, large electromagnetic calculations, etc. The proposed computer facility will enable the researchers that work in the Center as well as various collaborators and visitors to advance their research.

The approach is inspired from recent and current HPC focus areas in academic HPC facilities, including:

• HPC operations excellence and best practice

• Application performance and benchmarking

• HPC storage expertise

• Graphics processing unit (GPU) computing

• HPC visualization

The core design is based on implementations from major academic HPC facilities around the world and the software infrastructure will be entirely based on open source code. The environment will be deployed either as CPU or as GPU compute nodes. Our intention is to provide both a conventional computing environment and GPU accelerated infrastructure, for high demanding parallel applications. All compute nodes will be setup as data-less, with just a small disk for temporary data, which will reduce the overall cost and elevate the flexibility at the same time.

Wireless networks

Wireless access is provided through the eduRoam SSID.

A free wireless network, with limited access, is also available under the SSID "Computer Center".
No WPA, WEP or any other key or password is required.

Available through this network are WEB & e-mail facilities, only. In order to have access to any other facility, please use the wired network, or a VPN Connection.
Note: Permanent personel, or long-term visitors, may apply for a local account in order to use the VPN service provided by the Physics Department.
