Koios infrastructure

Intel Xeon Gold 6130

The CPU of the Koios compute nodes, two per node.

• 16 cores, or 32 SMT virtual cores
• 14 nm technology
• 2.10 GHz base frequency
• Vendor page

NVIDIA Tesla P100

The GPUs of the Koios GPU node, four cards (currently dedicated to a project).

• SXM2 module (not a PCIe card)
• 16 GB HBM2 memory, 732 GB/s
• 5.3 TFLOPS double precision, 10.6 TFLOPS single precision
• NVLink between all four GPUs: each GPU has four links of 20 GB/s per direction, two to one partner GPU (0–3, 1–2) and one to each of the other two (nvidia-smi topo -m on the node shows the layout)
• CUDA compute capability 6.0 (list of CUDA GPUs)
• Vendor datasheet

Interconnect

• Mellanox MT4115 ConnectX-4, 1× 100 Gb/s InfiniBand EDR per node
