Weighing over 340 tons, Summit takes up 5,600 sq. ft. of floor space at [[Oak Ridge National Laboratory]]. Summit consists of 256 compute racks, 40 storage racks, 18 switching director racks, and 4 infrastructure racks. Servers are linked via [[Mellanox]] [[IB EDR]] [[interconnect]] in a three-level non-blocking fat-tree topology. | Weighing over 340 tons, Summit takes up 5,600 sq. ft. of floor space at [[Oak Ridge National Laboratory]].

Communication between the two {{ibm|POWER9|l=arch}} processors is done over IBM’s X Bus. The X Bus is a 4-byte 16 GT/s link providing 64 GB/s of bidirectional bandwidth. A node has four PCIe Gen 4 slots consisting of two x16 (with CAPI support), a single x8 (also with CAPI support), and a single x4 slot. One of the x16 comes from one CPU, the other comes from the second. The x8 is configurable from either one of the CPUs and the last x4 slot comes from the second CPU only. The rest of the PCIe lanes used for various I/O applications (PEX, USB, BMC, and 1 Gbps Ethernet). Mellanox InfiniBand ConnectX5 (IB EDR) NIC which supports 100 Gbps of bi-directional traffic. This card sits on a PCIe Gen4 x8 shared slot which directly connects x8 lanes to each of the two processors. This enables each CPU to have direct access to the [[InfiniBand]] card, reducing bottlenecks. |
