Course: Introduction to Kebnekaise, 2022-01-19

Introduction to Kebnekaise

We begin with a short introduction to Linux, which is what is used on HPC2N's compute clusters, and the vast majority of HPC clusters on the planet. This part is only meant for complete beginners to the Linux operating system, and can be omitted if you are proficient already. See the schedule.

We then continue with an introduction to HPC and HPC2N, then move on to a walkthrough of the Kebnekaise system, including the GPUs and KNLs. In the afternoon we go through the module system and take a brief look at how to submit jobs. During the hands-on you will get the opportunity to try loading modules, compile a program, and submit a job to the Kebnekaise cluster.

Remote/online participation: The course will be completely online and we will use Zoom. More information about connecting and such will be sent to the participants close to the course.

Participation is free and open to all users from the SNIC HPC centres and academics throughout the Nordic region. 

Please make sure have an account at SUPR as well as at HPC2N if you want to participate in the hands-on part of the training. There will be a course project that can be used to run the examples in during the hands-on. If you don't have an account at SUPR and/or HPC2N, you will be contacted with further instructions for how to create those. You are encouraged to sign up to SUPR as soon as possible after registering for the course.

Course project: As part of the HPC2N hands-on, you will be given temporary access to a course project, which will be used for running the hands-on examples. There are some policies regarding this, that we ask that you follow:

  • You may be given access to the project before the course; please do not use the allocation for running your own codes in. Usage of the project before the course means the priority of jobs submitted to it goes down, diminishing the opportunity for you and your fellow participants to run the examples during the course. You can read more detailed information about the job policies at HPC2N here.
  • The course project will be open 1-2 weeks after the course, giving the participants the opportunity to test run examples and shorter codes related to the course. During this time, we ask that you only use it for running course related jobs. Use your own discretion, but it could be: (modified) examples from the hands-on, short personal codes that have been modified to test things learned at the course, etc.
  • Anyone found to be misusing the course project, using up large amounts of the allocation for their own production runs, will be removed from the course project.
  • You will likely also be given access to a storage area connected to the compute project. Any data you store there should be course-related and if you wish to save it you should copy it to somewhere else soon after the course as it will be deleted about a month later.

The course uses computing resources provided by the Swedish National Infrastructure for Computing (SNIC) at HPC2N partially funded by the Swedish Research Council through grant agreement no. 2018-05973.
