Core facility (CF)

Short Description

The server infrastructure comprises 15 high-performance computers with multi-core processors (up to 3 GHz):
8 x HP ProLiant
1 x supermicro 4 U 2x4-corel
1 x supermicro 1U 2x10-core
1 x supermicro 2 U 2x10 core
1 x supermicro 1U 2x24-core
2 x HE Intel Dual CPU

Use: Storage of protein structure data, calculation of protein classifications, derivation of energy functions for protein structure analysis, identification of transcription factor binding sites, immunoinformatics, etc.
In many cases, the results obtained are also made available to the scientific community as a web service.

The PC infrastructure comprises approx. 20 desktop computers (Linux, Windows, MacOS X)
Use: software development, data analysis, etc.
