Overview

The CUHK Central Cluster consists of 60 compute nodes, 1.5 Petabyte Lustre storage, 3 servers with GPU accelerators, a quad-CPU node with 3TB memory and an Infiniband EDR networking running at 100Gpbs connecting all nodes.  The Central Cluster is a subscription-based service requiring an application by the Principal Investigator (PI) of an ongoing research project.

  1. Major Components

    2. The Central Cluster is a collection of compute nodes, storage, and interconnected by high-throughput, low-latency network that allows researchers to run programs that cannot be done on their desktop or workstation computer.

    All the nodes of the system running CentOS 7 and Slurm are the workload manager of the Central Cluster. The major components of the system are:

    • 50 x compute nodes with dual Intel(R) Xeon(R) Gold 6130 CP@ 2.10GHz and 96GB memory.
    • 10 x compute nodes with dual Intel(R) Xeon(R) Gold 6130 CP@ 2.10GHz and 192GB memory.
    • One large memory compute nodes with 4 x Intel(R) Xeon(R) Gold 6142 CPU @ 2.60GHz and 3TB memory.
    • 7 x compute nodes with quad Intel(R) Xeon(R) Gold 6128 CPU @ 3.40GHz and 128GB memory.
    • 3 x compute nodes with dual Intel(R) Xeon(R) E5-2690 v3 CPU @ 2.60GHz and 128GB memory.
    • 4 x GPU nodes with three Tesla V100 (32GB Memory).
    • One GPU nodes with two Tesla P100 (16GB Memory).
    • A Lustre File System with capacity 1.5PB.
    • All compute nodes and storage nodes are interconnected by Infiniband EDR network at 100Gpbs.
