HPC Center user guides

_images/HPC.jpg

The use of the resources of TalTech HPC Centre requires an active Uni-ID account (an application form for non-employees/non-students can be found here.) Further the user needs to be added to the HPC-USERS group, please ask hpcsupport@taltech.ee to activate HPC access from your TalTech e-mail and provide your UniID (six letters taken from the user’s full name). In the case of using licensed programs, the user must also be added to the appropriate group. Here can be found more about available programs and licenses.

TalTech HPC Centre includes cluster, cloud and also is responsible for providing access to resources of LUMI supercomputer.

The cloud provides user ability to create virtual machines where the user has full admin rights and can install all the necessary software by her/himself. VMs can be connected from outside and can be used for providing web services. Accessible through the ETAIS website: https://etais.ee/using/.

The cluster has a Linux operating system (based on CentOS; Debian or Ubuntu on special purpose nodes) and uses SLURM as a batch scheduler and resource manager. Linux is the dominating operating system used for scientific computing and of now is the only operating system present in the Top500 list (a list of the 500 most powerful computers in the world). Linux command-line knowledge is essential for using the cluster. Resources on learning Linux can be found in our guide, including introductory lectures in Moodle. However, some graphical interface is available for data visualisation, copy and transfer.

LUMI supercomputer is the fastest supercomputer in Europe, the fifth fastest globally and the seventh greenest supercomputer on the planet. Specification of LUMI can be found here.
