Account Request

To get access to the DC3 systems you need to be either a HPC grant holder or a member of a group holding a current HPC grant.
To get an account please go to the following web-page: https://hpc.ku.dk

Connecting to DC3

In order to login to DC3 computational system, you must use the SSH protocol. This is provided by the "ssh" command on Unix-like systems (including Mac OS X) or by using an SSH-compatible application (e.g. PuTTY on Microsoft Windows). We recommend that you "forward" X11 connections when initiating an SSH session to DC3. For example, when using the ssh command on Unix-based systems, provide the "-Y" option:

ssh -Y jojo@fend01.hpc.ku.dk

In order to download/upload data from/to DC3 use the following command:

scp –pr user@host1:from_path_file1 user@host2:to_path_file2

for more information use man/info commands (man scp).

There are 5 frontend nodes available at the moment: fend01.hpc.ku.dk - fend05.hpc.ku.dk

Software

DC3 provides a rich set of HPC utilities, applications, compilers and programming libraries. If there is something missing that you want, send email to nuterman@nbi.ku.dk with your request and evaluate it for appropriateness, cost, effort, and benfit to the community. More information about available software and how you use it is included in the Available Software section.
