Lightweight HPC – Free access to powerful computing servers for UiO users

Lightweight HPC (freebio, freebio2, bioint01, bioint02, bioint03, bioint04) is a resource for all UiO users interested in testing out scientific applications, simulation software, parallel code etc. This service is free of charge for all UiO users.

These are stand-alone machines for low-threshold use, and with best-effort user support.

What are Freebio & Freebio2 ?

  • The systems are ARM based servers running Linux. The processor is from High Silicon, model Hi1616. The system has 64 cores, 256 GiB of memory and 36 TiB of local disk. The very few ARM based HPC servers in production in Norway. Run a large set of software. Popular with Julia and R. Freebio has a large set of bio-informatic databases installed.

How to use

Freebio, Freebio2 and Bioint0[1-4] are available to all UiO users and partners that are granted an UiO account.

Get access by filling in this nettskjema.

See more about Freebio or more about Bioint01 for login information.

What are bioint0[1-4]?

  • bioint01 has AMD EPYC 7501 CPUs, 128 cores and 128 GB RAM
  • bioint0[2-4] have Intel Xeon E5-2690 CPUs, 32 cores and 512 GB RAM each
  • The system is installed with Linux and a selection of software, common software is installed as modules and yet other per demand.  bioint01 has 7.3 TB local disk storage available as scratch area on /work
  • Note that there is no batch system, i.e you can not run jobs that span over two machines (like on a typical HPC system). There is therefore no queue system, so use the machines in a solidaric way!

What can I store in Light-HPC system ?

Shared home directory

Users of the Lightweight HPC machines get a home directory that is shared between all Lightweight HPC machines but that is separate from their regular UiO home directory allowing for easy data transfer between the machines.


We install software on lightHPC using the EasyBuild framework.

The module system allows you to see what software is available and load it for use.


To see available software, please run the following command:

module avail

To load a module, use name and full version of the module:

module load <some-package-listed-in-module-avail>

For example:

module load R-bundle-Bioconductor/3.12-foss-2020b-R-4.0.3 

To get a clean environment and unload all modules:

module purge

Installed software

  • Python, R, Bioconductor, Julia, Singularity (installed on all six servers)
  • MATLAB, Gaussian, Molpro (only for x86_64, i.e. bioint0[1-4]
  • GATK, Keras, Tensorflow (only aarch64, i.e. freebio and freebio2 at the moment)
  • Qiime (only at bioint01 at the moment)

Software requests

If you need additional software or want us to upgrade an existing software package, we are happy to do this for you (or help you to install it yourself if you prefer that). In order for us to get all the relevant information and take care of the installation as quick as possible, we have created a software request form. After filling in the form a ticket will be created in RT and we will get back to you with the installation progress.
