1 System Architecture

The bwForCluster Helix is a high performance supercomputer with high speed interconnect. Is composed of login nodes, compute nodes and parallel storage systems connected by fast data networks. It is connected to the Internet via Baden Württemberg's extended LAN BelWü.

2 Operating System and Software

  • Operating system: RedHat
  • Queuing system: Slurm
  • Access to application software: Environment Modules

3.2 Intel Nodes

4 Storage Architecture

There is one storage system providing a large parallel file system based on IBM Spectrum Scale for $HOME, for workspaces, and for temporary job data.

5 Network

The components of the cluster are connected via two independent networks, a management network (Ethernet and IPMI) and an Infiniband fabric for MPI communication and storage access. The Infiniband backbone is a fully non-blocking fabric with 200 GB/s data speed. The compute nodes are connected with different data speeds according to the requirements of the configuration.
