HLRN

QUICK FACTS
Industry: National Laboratory

The North German Supercomputing Alliance (HLRN) provides scientists across seven North-German states with state-of-the-art storage and compute resources to accelerate scientific breakthroughs in the fields of physics, chemistry, fluid dynamics, engineering and the environment. Established in 2001, the alliance currently supports scientists and researchers from Berlin, Brandenburg, Bremen, Hamburg, Mecklenburg-Vorpommern, Niedersachsen and Schleswig-Holstein. Currently, the third generation supercomputer, HLRN-III is in operation.

The scientists, many of whom come from North German universities and other scientific institutions, have combined resources and funding from their respective states and the German federal government to create a powerful, distributed supercomputer system. As the foundation for Big Data analytics and advanced
scientific research infrastructure, the system is operated by a team of experts at Zuse Institute Berlin (ZIB) and at the High Performance Computing Center at Leibniz University in Hannover (RRZN).

 

CHALLENGES

  • Diverse research requirements required an optimal balance between compute and storage resources
  • Complex modeling and data-intensive computations required high-bandwidth storage performance
  • Different categories of storage were required to support critical programs, intermediate project data and final research results
  • Ensuring reliable, extremely fast data sharing between scientists utilizing resources in Berlin and Hannover necessitated distributed storage that scaled seamlessly

SOLUTION

  • HLRN is a distributed peta-scale supercomputing system based on Cray XC30 and DDN’s SFA12K®-40 with Lustre and DDN’s GRIDSCaler file system appliance with GPFS mirrored at both sites in Berlin and Hanover

RESULTS

  • Crucial balance of storage I/O for Petascale Compute was achieved
  • Long-lasting improvement of return on compute to support more science, from developing new molecular modeling techniques to expediting the design of new drugs or creating wind stream simulations

BUSINESS BENEFITS

  • HLRN scientists can access powerful compute and storage resources to accelerate research and drive scientific breakthroughs
  • High-density, scalable storage enables HLRN to increase research support while reducing energy consumption for lowered TCO
  • HLRN is poised to drive increased cooperation with international research groups

TECHNICAL BENEFITS

  • DDN delivered nearly four times greater bandwidth performance than the previous storage system
  • By striking the right balance between compute and storage requirements, HLRN can optimize its use of up to 30 software packages, tools and libraries
  • DDN worked seamlessly with HLRN’s Lustre and GPFS parallel file systems to support both temporary (work) and permanent (home) storage
  • With policy-driven snapshots, HLRN can provide an extra layer of against accidental data deletion, corruption or viruses
