PSC’s newest supercomputer


Bridges-2, PSC’s newest supercomputer, began early operations in February 2021.  It is funded  by a $10-million grant from the National Science Foundation.

Bridges-2 provides transformative capability for rapidly evolving, computation-intensive and data-intensive research, creating opportunities for collaboration and convergence research. It supports both traditional and non-traditional research communities and applications. Bridges-2 is integrating new technologies for converged, scalable HPC, machine learning and data; prioritizing researcher productivity and ease of use; and providing an extensible architecture for interoperation with complementary data-intensive projects, campus resources, and clouds.

Bridges-2 is available at no cost for research and education, and at cost-recovery rates for other purposes.

Regular Memory

Regular Memory (RM) nodes will provide extremely powerful general-purpose computing, machine learning and data analytics, AI inferencing, and pre- and post-processing.

488 RM nodes will have 256GB of RAM, and 16 will have 512GB of RAM. All RM nodes will have:

  • Two AMD EPYC 7742 CPUS, each with:
    • 64 cores
    • 2.25-3.40GHz
    • 256MB L3
    • 8 memory channels
  • NVMe SSD (3.84TB)
  • Mellanox ConnectX-6 HDR Infiniband 200Gb/s Adapter
Extreme Memory

Bridges-2 Extreme Memory (EM) nodes will provide 4TB of shared memory for genome sequence assembly, graph analytics, statistics, and other applications requiring a large amount of memory for which distributed-memory implementations are not available. Each of Bridges-2’s 4 EM nodes will consist of:

  • Four Intel Xeon Platinum 8260M “Cascade Lake” CPUs:
    • 24 cores
    • 2.40–3.90GHz
  • 35.75MB LLC 6 memory channels
  • 4TB of RAM: DDR4-2933
  • NVMe SSD (7.68TB)
  • Mellanox ConnectX-6 HDR InfiniBand 200Gb/s Adapter

Bridges-2 24 GPU nodes provide exceptional performance and scalability for deep learning and accelerated computing, with a total of 40,960 CUDA cores and 5,120 tensor cores. Each GPU node will contain:

  • Eight NVIDIA Tesla V100-32GB SXM2 GPUs
  • 1 Pf/s tensor
  • Two Intel Xeon Gold 6248 “Cascade Lake” CPUs:
    • 20 cores, 2.50–3.90GHz, 27.5MB LLC, 6 memory channels
  • 512GB of RAM: DDR4-2933
  • 7.68TB NVMe SSD
  • Two Mellanox ConnectX-6 HDR Infiniband 200Gb/s Adapter
