INFORMATION TECHNOLOGY SERVICES (ITS)
Information Technology Services (ITS) provides comprehensive information technology services with a state-of-the-art IT environment to support teaching, learning, research and administration of the University. Its facilities include an advanced campus network, powerful central servers, high-performance computer (HPC) clusters, cloud computing and modern learning environment, and its services include portal services, learning management and lecture capture services, centrally coordinated software, user support service and web-based administrative applications.
HKU PORTAL SERVICES
ITS runs 24-hour, non-stop system and network services to support the IT needs of the University. All students are given a computer account, identified uniquely by an HKU Portal UID (User Identification) and an associated PIN (Personal Identification Number), for accessing a wide range of network services and applications conveniently.
The HKU Portal provides a user-friendly and easy-to-access interface for University members to access all the centrally provided IT services including services offered under the Student Information System (SIS), electronic mail, learning management system, web-based administrative applications, and Library services.
COMPUTER AND RESEARCH SUPPORT FACILITIES
Powerful central computer servers support various web-based applications, departmental web sites and electronic email.
ITS provides expertise and central support in high performance computing (HPC) to facilitate compute-intensive research activities of the University. A 2,320-core HPC system (theoretical peak power of 103.4 Tera-FLOPS) and another new 780 Tera-FLOPS HPC system that equipped with the latest technologies including fast multi-core processors, Nvidia Graphics Processing Unit (GPU) and Lustre parallel file-system will be added in early 2021 for supporting compute-intensive and accelerated computing. An Artificial Intelligence (AI) platform (total 6.5 Peta-FLOPS Deep Learning Performance) will be put into production by phases for supporting AI, Machine Learning and Deep Learning researches.
HKU CAMPUS NETWORK
ITS has installed a high-speed and sophisticated campus network based on 10-Gigabit Ethernet and Fast Ethernet technologies with over 55,000 network access points installed which links together all the computer servers, workstations and PCs in the main and remote campuses.
Wireless access to the campus network and Internet is provided by over 6,000 WiFi access points and is available in all centrally-administered classrooms, public areas in the main campus, department offices and halls of student residence. Apart from the University’s WiFi network “HKU”, students can also enjoy WiFi access off-campus at CSL and Y5Zone WiFi hotspots in town, and at other local and overseas universities using “eduroam”.
The University of Hong Kong is a member of the Joint Universities Computer Centre (JUCC) that manages HARNET (the Hongkong Academic and Research NETwork) and coordinates inter-campus network services among the eight tertiary institutions in Hong Kong. The HKU campus network is connected to other tertiary institutions in Hong Kong through a resilient network backbone of HARNET supporting two 10Gbps ports at each institution to cater for future expansion.
ITS, through the Learning Environment Services (LES) Team, looks after the central learning environment of the University, comprising classrooms, lecture theatres, Chi Wah Learning Commons, The Curve (1/F and 2/F of KK Leung Building) and The Lounge (MB238 of Main Building). A wide variety of facilities is provided to support the technology-enabled learning experience. For example, the Digital Literacy Laboratory (DLL) has powerful iMacs and well-equipped production studios together with technical support for multimedia production. Communal PCs come with latest version of software packages, including word-processing, web page design, graphical and multimedia tools, and statistical analysis. uPrint Service (laser printing service) is available for both communal and personal laptop computers which are connected to the campus network through WiFi. A Materializer 3D Printer is also available in the Chi Wah Learning Commons.
ITS provides a wide range of IT support services to members of the University. Orientation courses are offered to new students at the start of each academic year. Regular IT seminars, induction courses and training workshops on popular IT topics and commonly used software packages are also held throughout the year. Students may visit the Service Desk and the General Enquiry Counter on the 1/F of Library Building (Old Wing) or through the multiple channels described at https://www.its.hku.hk/service-desk to get assistance in using the central computing and network services.
