System Architecture

The bwForCluster Helix is a high performance supercomputer with high speed interconnect. The system consists of compute nodes (CPU and GPU nodes), some infrastructure nodes for login and administration and a storage system. All components are connected via a fast Infiniband network. The login nodes are also connected to the Internet via Baden Württemberg's extended LAN BelWü.

The lines marked in blue are in particular relevant for Slurm jobs.

Storage Architecture

There is one storage system providing a large parallel file system based on IBM Storage Scale for $HOME, for workspaces, and for temporary job data. The compute nodes do not have local disks.

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 node configuration. The term HDR100 stands for 100 Gb/s and HDR200 for 200 Gb/s.
