LPCT Cluster

Overview

Welcome to the LPCT Cluster, a HPC platform featuring a heterogeneous architecture with x86 CPUs and NVIDIA GPUs.

Cluster Specifications

Fronted Nodes

Login Nodes

The cluster provides 4 login nodes:

Visualization Nodes

Dedicated nodes for graphical applications with GPU acceleration:

Access is available via:

Graphical Session

X11 Forwarding

The simplest way to access a graphical interface on the cluster is via X11 forwarding. Use the -X flag with SSH:

$ ssh -X USER@lpct-login

For better performance, enable compression by adding the -C flag:

$ ssh -XC USER@lpct-login

TurboVNC

For higher-performance remote desktop access, use TurboVNC. Note that, only securized sessions via SSH are allowed. The required TurboVNC client version is 3.2 and can be installed from the release website of turbovnc.

Setting up a TurboVNC session

  1. On the login node, run:

    $ /opt/TurboVNC/bin/vncpasswd

    and choose your VNC password

  2. Then run:

    $ /opt/TurboVNC/bin/vncserver

    to start a new session

  3. A message like this should appear:

    Desktop 'TurboVNC: lpct-login:n (USER)' started on display lpct-login:n

    where the number n indicates the X display number of the TurboVNC session
