Computer center

The IAP has a excellent computing infrastructure available. The core is build by 2 backbone switches by the company of Cisco. They supplies all desktops with GBit/s ethernet network connections in IAP.

The IAP is connected to the internet via the Deutsches Forschungsnetz (DFN). The band width of the connection is 150 MBit/s. Corresponding equipment secures the access to the IAP network. There are used different technologies to prevent unauthorized access, impact of virusses and spam.

Demanding scientific tasks require demanding computer equipment placed in the High Performance Computing (HPC) segment at IAP. Central resources are the Vector Computer system by the company of NEC and a Scalar Computer system by the company of SGI. The Vector Computer has 4 prozessors with 8 GFlop ( Billion Floatingpoint Operations in on second) at a time peak performance. The SX6-4B is fitted out with 32 GByte main memory and 0,75 TByte disk space. Main application is the development and calculating of own codes (in FORTRAN), as well as foreign programms in the area of climate dynamic and modelling.

The Scalar Computer is a system with 64 cores (64 logical CPU's), 192 GByte main memory and 2 terrabyte disk space. The Linux based system by the company of SGI is excellent suitable for calculation of parallizied codes and has a very high throughput.

Not least caused by these HPC computers the need of storage capacity is immense at IAP. Scientific experiments and messurements require and produce enormous amounts of datas. To cope with corresponding datas the IAP has a magnetic tape roboter system, a so called tape library by the company of Quantum available. The capacity amounts to 200 TByte in the moment, controlled by a computer system by the company of SGI.

Each of the 3 departments of IAP has a smaller Server system as well as a multitude of desktop and experimental PC's for more importend tasks available.
