Information on the resources

Resource bwgrid

The system consists of a X86 cluster with 140 nodes.

The computer nodes are IBM blade server HS21XM. Each one is equipped with 2 CPUs Intel Xeon E5440 (Hapertown), 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). Each node is equipped with an internal 140 GB hard disk. 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 SFS3 storage system, available on all nodes and the frontends as a Lustre file system. 32 TB of storage space are available.

The operating system is Scientific Linux 5.0.

The bwGRiD resources in Heidelberg and Mannheim are operated as a single, integrated system. Access to the integrated system is available vie the middleware system in Mannheim:

  • Globus Toolkit 4.0.8 (host name: gtbw.grid.uni-mannheim.de)

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

  • Complete distribution SL 5.0
  • Open-MPI, MVAPICH
  • Intel Cluster Toolkit Compiler Suite
