Connecting to High-Performance Computing Virtual Private Network

Users can connect to NREL's high-performance computing (HPC) systems via VPN (virtual private network).

You do not need the VPN connection if...

You are an NREL employee using an NREL device (while on-site you may connect directly; while off-site, use your existing GlobalProtect External VPN Connection).

You may need the VPN if...

  • You are a non-NREL HPC user or an NREL employee using a non-NREL device.
  • You need to use features such as web-based applications, X11 applications, or perform file transfers on non-Eagle systems.
  • Your organization blocks outbound SSH connections.

A Linux client is not currently available, but it will be added soon.

Note:  NREL High-Performance Computing does not provide technical support, and you may need to seek assistance from your IT department when installing software.
