How to log in

Introduction

The hpc clusters are only accessible via ssh (secure shell). To log in you need an ssh client. If you use Windows, you can download and use PuTTY, Macintosh and Linux computers already have an ssh client built in. There is no need to log in to a bastion host first, you can log in from anywhere in the world.

You'll also need a valid NetID and it needs to be enabled for access to one of the clusters.

How to log in from Windows

An often used ssh client for Windows is PuTTY. If you use a Windows PC or a laptop that is provided and maintained by the TU Delft, it is already there, if you use your own Windows computer, you'll have to download and install PuTTY first.

How to log in from Mac OS X

Mac OS X is in fact a full blown UNIX system under the hood. A terminal program comes standard with OS X, you can find it in Applications -> Utilities on every Mac. Once the terminal program is started you'll get a command promt, now just type:

ssh <netid>@hpc99.tudelft.net

Where <netid> is of course your own netid. Instead if hpc99 you type the actual name of the cluster that you have access to.

How to log in from Linux

There are many different flavours of Linux, each with their own desktop environments and customizations. Nearly every Linux system comes with a terminal program of some sort. Find the terminal program on your system and run it, once you get a comand prompt type:

ssh <netid>@hpc99.tudelft.net

Where <netid> is of course your own netid. Instead if hpc99 you type the actual name of the cluster that you have access to.
