JULIA (Cray pilot)

JULIA is one of the two pilot systems developed by Cray in the Pre-Commercial Procurement during the HBP Ramp-up Phase. It is located at Jülich Supercomputing Centre (JSC), Forschungszentrum Jülich, Germany.

The Pre-Commercial Procurement (PCP) was focused on the areas dense memory integration, scalable visualization and dynamic resource management. Cray addressed these topics the following way:

  • Dense memory integration: DataWarp nodes
  • Scalable visualization: Tightly integrated visualization nodes
  • Dynamic resource management: Integration with SLURM

The key technologies used for the Cray pilot system are

  • KNL-based compute nodes
  • 100 Gbps network technology (Omni-Path)
  • NVRAM technologies
  • Coherent software stack

Both PCP pilot systems are installed at Jülich Supercomputing Centre and integrated into the data infrastructure: The GPFS cluster JUST is accessible from all nodes. A 10 Gigabit-Ethernet connectivity for remote visualization is available.

The Pilot systems will be integrated into the HBP HPAC Platform AAI.

JULIA is available since first week of August 2016.
