IT hot spots

As Norway's premier science and technology university, NTNU has a wealth of computer labs for students to use, as well as a WiFi zone that extends from the Gløshaugen and Dragvoll campuses to downtown Trondheim.

 

NTNU's 65 main computer labs are located on the Gløshaugen and Dragvoll campuses, and all libraries have banks of computers that can be used to both access library services as well as the Internet. Many computer labs will require you to swipe your NTNU ID for access, and some labs are restricted to students from specific departments. Check the computer lab list before you go to be certain, or check with administrators in your department for specific recommendations.

Wireless world
If you've got your own computer or WiFi-enabled mobile phone, you can pluck Internet access from the air by using NTNU's WiFi system, called Wireless Trondheim. While Wireless Trondheim mainly serves NTNU students and staff, it's also been designed so that researchers can use the network for research. This makes Trondheim one of the few cities in the world that offers not only a wireless city system but an entire city of users who help make the city a gigantic wireless network laboratory.

The system is designed with backups and parallel structures so that any experiments conducted in the wireless 'lab' won't affect your ability to use the system. And of course your communications remain confidential.

Supercomputing facilities
NTNU has its own supercomputer, called Njord, named after the Norwegian god who is the protector of seafarers and fishermen and who sends favourable winds and calm seas. Njord is an IBM p575+ interconnected with a high-bandwidth low-latency switch network (HPS). When it was installed in August of 2006, it was one of the most powerful supercomputers in Europe, and doubled Norway's supercomputing capacity in one fell swoop. NTNU's researchers use the machine for a variety of projects, including helping with the 3-D visualization of oil reservoirs and water and sediment flow in rivers. The Norwegian Meterological Institute also uses time on the machine to create more detailed and real-time weather forecasts.

For those who are curious about the technical details, Njord has a total of 65 nodes partitioned into 59 compute nodes, 4 I/O nodes and 2 login nodes. All 59 compute nodes are shared memory nodes with 8 dual-core power5+ processors 1.9 Ghz. Four of the compute nodes have 128 GB memory, while the remaining 55 have 32 GB of memory.

The system is well-suited for large-scale parallel MPI and OpenMP applications, as well as applications that combine these two communication paradigms.However, all high performance computing in Norway is controlled by a cooperative called NOTUR, which ensures that computing time on the country's four supercomputers is properly allocated. You can read more about NOTUR, including about how to apply for computer time, on the consortium's own web pages.

Wireless Trondheim

Trondheim is often called the Silicon Valley of the North, because it is home to offices for three of the world's top search engine companies, and because of the many NTNU IT spinoffs, including Fast Search and Transfer, Adactus, and Mison. So it seemed natural to transform the entire city of Trondheim into a giant research laboratory for wireless networks. Thus was Wireless Trondheim born in September, 2006.

NOTUR

NOTUR, the Norwegian Metacenter for Computational Science, oversees the allocation of time for Norway's 4 high performance computers. In addition to NTNU's Njord, Norway is home to Hexagon, a Cray XT4 computer housed at the University of Bergen; Stallo, a Cluster Platform 3000 BL460c at the University of Tromsø; and Titan, a Sun X2200 at the University of Oslo. NTNU students and researchers can apply to NOTUR to use time on any of these machines as needed. For more information contact NOTUR at info@notur.no
