Project Summary

miniHPC is a small high-performance computing (HPC) cluster. The purpose of designing and purchasing miniHPC is two-fold:
(1) to offer a platform for teaching parallel programming to students in order to achieve high performance computations and
(2) to have a fully-controlled experimental platform for conducting leading-edge scientific investigations in HPC.

The miniHPC has a peak performance of 28.9 double-precision TFLOP/s. The miniHPC has 4 types of nodes (see Table 1), Intel Xeon E5-2640 nodes, Intel Xeon Phi Knights Landing (KNL) 7210 nodes, Intel Xeon Gold 6258 nodes, and AMD EPYC 7742 nodes (see Table 2). The Intel Xeon E5-2640 nodes consist of 22 computing nodes, 1 login node, and 1 node for storage. The Intel Xeon Phi nodes consist of 4 computing nodes. The Intel Xeon Gold 6258 nodes and the AMD EPYC 7742 nodes are both computing nodes.

  1. E5-2640-v4-25M-Cache-2_40-GHz
  2. Processor-7210-16GB-1_30-GHz-64-core

Node Intel Xeon Gold 6258R contains 2 x NVidia A100-PCIE-40GB GPUs ( ).

All nodes are interconnected through two different types of interconnection networks. The first network is an Ethernet network with 10 Gbit / s speed, reserved for users and administrators access. The second network is the fastest network, an Intel Omni-Path network with 100 Gbit / s speed, reserved for the high-speed communication between the computing nodes. The topology of this second network interconnects the 30 (24 Intel Xeon E5-2640, 4 Intel Xeon Phi or KNL, and 1 Xeon Gold 6258R, 1 AMD EPYC 7742) of the miniHPC cluster via a two-level fat-tree topology.
