Welcome to the FAQ page for Berzelius!
On this page, you’ll find answers to commonly asked questions about our HPC environment. These FAQs are here to provide you with troubleshooting tips and best practices to optimize your experience on our cluster.
A: This message indicates that your quota is almost full. You can check your quota by nscquota
.
You can use ncdu
to check which folders are taking the most space.
ncdu /home/<your username>
ncdu /proj/<your project>/users/<your username>
Please note that your /home/<your username>
has only a quota of 20 GB. You need to move the large directory from your home directory to your project directory and create a symlink from your project directory pointing to its original location.
For example, we move the .conda
directory to the project directory
mv ~/.conda /proj/<your project>/users/<your username>/
ln -s /proj/<your project>/users/<your username>/.conda ~/.conda
A: You can extend the time limit of a running job by using the command nsc-boost-timelimit
on the login node. Please read the guide for NSC boost-tools.
A: Please make sure that you have installed the GPU version of PyTorch/TensorFlow.
To check the installation info:
# If you installed the package via pip
pip show pytorch
# If you installed the package via conda
conda list pytorch

A: The recommended way to acknowledge access to Berzelius is:
“The computations/data handling/[SIMILAR] were/was enabled by the Berzelius resource provided by the Knut and Alice Wallenberg Foundation at the National Supercomputer Centre.”
If applicable, also add an acknowledgement for application support: “[NAME] at the National Supercomputer Centre is acknowledged for assistance concerning technical and implementational aspects [OR SIMILAR] in making the code run [OR SIMILAR] on the Berzelius resource.”
or
“We thank [NAME] at NSC for [his/her] assistance with [describe tasks such as porting, optimization, etc.], which was made possible through application support provided by National Supercomputer Centre at Linköping University.”
