Dragon`s-Rock Cluster

SCAI operates a modern powerful and diverse IT infrastructure including several High Performance Computing (HPC) and Big Data clusters. This includes:

  • an HPC-HPDA cluster with 128 nodes (4096 Skylake EP CPU cores, Omnipath fabric with fully bisectional 100 Gbit bandwidth in fat-tree topology) plus 16 nodes with additional local PCIe NVMe for data analytics,
  • an HPC cluster with ~300 nodes (4096 Ivy Bridge CPU cores, 640 AMD cores on big memory machine, FDR Infiniband 56GBit interconnect),
  • a shared parallel distributed file system of ~480 TB capacity distributed over 13 storage and metadata nodes connected with Infiniband and Omnipath,
  • dedicated nodes with NVIDIA Tesla GPUs (including 12x Tesla A100 & 8x Tesla V100) and Intel KNL, FPGAs,
  • a data-analytics cluster based on distributed Ceph object storage with ~400TB capacity and various virtualization hosts for running Hadoop, Accumulo, Cassandra,
  • a Kubernetes Cluster for production hosting of microservices including a Ceph-based storage system with more than 1PB of capacity.

SCAI is a member of and Cloud Computing provider in European Open Science Cloud through the participation in NGI_DE in EGI-ACE (providing an EGI FedCloud site).

As a member of the Fraunhofer Competence Network Quantum Computing, SCAI has access to a quantum computer operated by IBM at its location in Ehningen, Baden-Württemberg.

Cloud Computing

Over the last years, Cloud Computing has evolved to an alternative or an extension of the in-house IT infrastructure. Benefits are greater flexibility and lower costs in the medium term though resource usage that is adapted to the respective demand. There are different technical realisation of Cloud Computing depending on the application: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) und Software as a Service  (SaaS), with a decreasing  dependency of the user (or customer) regarding the hardware actually used by the Cloud service provider. Furthermore, Clouds are distinguished between so-called public Clouds (commercial offerings), in-house Clouds (which may be operated by the local IT department or a commercial provider), hybrid Clouds that combine both types, and community Clouds that are operated by and for a dedicated community. However, there are a number of not yet fully solved matters. In particular, these concern Interoperability, Security (vendor lock-in), Data Protection, Service Level Agreements and Software Licence Management. In several national and European funded projects Fraunhofer SCAI has developed approaches addressing these matters and has acquired expertise, which we offer to our customers and partners.
