High Performance Computers at Information Technology
Introduction
At the Department of Scientific Computing, Information Technology, Uppsala University, there are currently four parallel high-performance computer systems in operation.
- Ngorongoro. The main HPC system, installed in December 2001. A SunFire 15k with 48 processors and 48 GByte memory. Theoretical peak performance is 86.4 Gflop/s.
- Albireo. An HPC computer with a unique architecture, installed 1999. A Sun WildFire system with 32 processors and 6 GByte memory. Theoretical peak performance is 16 Gflop/s.
- Yggdrasil. An older HPC system, installed 1996. Three interconnected DEC Server 8200, with in total 12 processors and 3 GByte memory. Theoretical peak performance is 7.2 Gflop/s.
- Grendel. A Linux cluster, installed in May 2001 in collaboration with NSC. The system consists of 16 PC, interconnected with 100 MBit Ethernet. Theoretical peak performance is 32 Gflop/s.
Research
At the Department of Scientific Computing (TDB), high-performance computing is used as integrated part of much of the research in algorithm and program development. There are also a number of research projects dealing directly with issues in the HPC field, some of which are performed in collaboration with the UART research group at the Department of Computer Systems.
Education
Each year, a large number of courses in different undergraduate programs use the HPC systems. Furthermore, a number of advanced, graduate level courses are given regularly.
