General Information

As a partner in the bwGRiD and within the framework of the D-Grid Project, funded by the Federal Ministry of Education and Research, the University of Tübingen provides virtual organisations with the opportunity to use computing resources on a cluster system via the Tübingen Data Processing Centre (ZDV).

The Tübingen location will be registered in the D-Grid shortly and further information will be published soon.

Information on the resources

The system consists of an X86 cluster with 140 nodes and was procured within the framework of the special D-Grid investment in 2007 for all locations of the bwGRiD by the HLRS. The resource will soon be available to all virtual organisations in the D-Grid.

The computer nodes are IBM blade server HS21XM. Each one is equipped with 2 Intel Xeon E5440 (Hapertown) CPUs, with a clock rate of 2.83 GHz, 12 MB cache size and a bus speed of 1333 MHz. Main memory size is 16 GB per node (2 GB per core). Further information is available in the product description and in the data sheet.

The frontend system consists of an IBM x3650 server with the same specifications as the computer nodes. . An InfiniBand network with double speed (DDR) connects the nodes, set up using Voltaire switches Voltaire Grid Director ISR 2012.

Hard disk storage for computing jobs is provided on a HP SFS storage system, available on all nodes and the frontends as a Lustre file system. 60 TB of storage space are available.

The operating system is Scientific Linux 5.0.

Access will soon be available through the following middleware systems:

  • Globus Toolkit 4.0.6 (gt4.uni-tuebingen.de)

On the system, the following important software packages are provided:

  • Complete distribution SL 5.5
  • MVAPICH
  • …

A user documentation covering technical questions and regulations for the utilisation of this resource is available in the Tuegrid Wiki of the ZDV (in German).
