Background

So far, supercomputers work on tasks in a largely autonomous way. The aim in future is for scientists to be able to intervene in the processes of applications and to control them interactively. This means that the computers must process considerably more data than even the enormous amounts that already arise for simulations of the human brain. The special challenge for the computers of the future is that the additional data must be rapidly analysed and visualized in parallel to the main application. To enable the development of necessary technologies and architectures the Human Brain Project launched a Pre-Commercial Procurement (PCP) of R&D services. The final phase of this PCP ran from July 2015 until January 2017. During this phase, the 2 remaining competitors, Cray and a consortium of IBM and NVIDIA, delivered each a pilot system.

PCP Pilot Systems

The PCP pilot systems serve the purpose of testing the solutions proposed by the contractors of the PCP for real-world neuroscience applications.

JULIA (Cray)

JULIA has been discontinued at the end of 2018.

This former JULIA system was based on the Cray CS-Storm architecture and comprised 60 compute nodes with the following features:

  • 1 Intel Xeon Phi Processor 7210 (1.3 GHz, 64 cores, 4 threads/core)
  • 16 GByte MDCRAM, 96 DDR4 memory

The nodes were interconnected in a tree topology using the new Intel OPA network technology. Additionally the system comprised DataWarp and visualisation nodes.

The name is derived from JUelich and GLIA, a type of cell in the nervous system.

JURON (IBM+NVIDIA)

This pilot system comprises 18 IBM S822LC servers ("Minksky") each with

  • 2 IBM POWER8 processors (up to 4.023 GHz, 2*10 cores, 8 threads/core)
  • 4 NVIDIA Tesla P100 GPUs ("Pascal")
  • 4x16 GByte HBM memory attached to GPU
  • 256 GByte DDR4 memory attached to the POWER8 processors
  • 1.6 GByte NVMe SSD

All nodes are connected to a single Mellanox InfiniBand EDR switch.

For more technical information see C. Hagleitner "Minsky architecture and the HPB PCP Prototype"

The name is derived from JUelich and neuRON, a type of cell in the nervous system.
