Differences between Computerome 1.0 and Computerome 2.0

Computerome 2.0 has been built with similar principles and technologies, as Computerome 1.0. Those users, who will migrate their Computerome 1.0 projects to the new cluster, will experience the following differences:

  • The 2-factor authentication happens with either SMS codes or the Entrust IdentityGuard soft token. See the guide on how to set up this soft token. No other soft tokens (e.g. Google Authenticator) are available for Computerome 2.0.  
  • The virtual desktop solution relies on the regular ThinLinc client, which can be downloaded from Cendio’s website. Read more on this here.Changes in the default project directory structure compared to the one in Computerome 1.0:

    /home/projects/<PROJECT>/archive is removed. Computerome 2.0 does not provide archiving services./home/projects/<PROJECT>/backup has been created. In Computerome 2.0, only the data physically stored in the backup directory is backed up for disaster recovery purposes./home/people/<user> has now a 10 GB quota on each personal directory.The support email for Computerome 2.0 changed to computerome@dtu.dk. Computerome 1.0 related requests and incidents remain to be reported to hpc@bio.dtu.dk.

    There is no difference between Computerome 1.0 and Computerome 2.0 regarding:

    Setup and Security framework

    The Danish National Supercomputer for Life Sciences has an ultra high-density footprint, and is installed in two 500kW containerized Tier IV data center modules.

    The system is designed using the bioinformatics reference architecture developed by CBS over the past 20 years and using the standard practices in the industry. It has a full set of comprehensive tools for both management and usage of the system. To get acquainted with the physical Hardware setup please visit here.

    file access issue

    Dell/EMC is currently working to fix a flawed switch in our Isilon storage backend.

    This has caused random errors, where some users have received "access denied" on files and directories.

    As an unfortunate side effect, it has also caused some users' jobs to terminate prematurely.

    Update: 2021.06.28, 10:30 CEST

    Isilon file and directory access is back and stable, with no further drop-outs since Friday.

    Computerome has returned to normal operations again, and we will be monitoring the situation closely.

    titleComputerome and the Tryggve project

    Computerome is a building-block in the Tryggve project that is working to establish a Nordic platform for collaboration on sensitive data, and that is funded by NeIC and the ELIXIR nodes in Denmark, Finland, Norway and Sweden.

    The Tryggve project welcomes use-cases from researchers collaborating on sensitive data with researchers in other Nordic countries. Please follow instructions on the Tryggve Getting Started page.

    As part of the Computerome engagement in Tryggve, Computerome is committed to the Tryggve Code of Conduct.




    Info
    titleThe Name


    The Computerome (pronunciation: \kəm-ˈpyü-tər-ōm\) cluster supercomputer is named in accordance with the use of the '-ome' suffix in the field of study in biology.

    Computerome is housed at DTU Risø Campus.
