Hardware Environment at NCI’s Supercomputer

Raijin  

The original Raijin system was installed in 2012 and entered production use in June 2013. System updates entered production in November 2016, and again in mid-2017. Raijin currently comprises:

  • 84,656 cores (Intel Xeon Sandy Bridge 2.6 GHz, Broadwell 2.6 GHz) in 4416 compute nodes
  • 120 NVIDIA Tesla K80 GPUs in 30 nodes and 8 NVIDIA Tesla P100 GPUs in 2 nodes
  • 32 Intel Xeon Phi (64 core Knights Landing, 1.3 GHz) in 32 compute nodes
  • 4 IBM POWER8 nodes (64 cores running at 4.02GHz)
  • 300 Terabytes of main memory
  • Hybrid FDR/EDR Mellanox Infiniband full fat tree interconnect (up to 100 Gb/sec)
  • 8 Petabytes of high-performance operational storage capacity

Raijin is supported by 37PB of project storage space for big data.

The system is currently undergoing a process to refresh the hardware. More details will be available soon.
