Our new HPC cluster is called ukko2. This cluster is initially only available to research personnel of the CS Department. If you cannot login, please contact IT support via helpdesk@helsinki.fi.
On the ukko2 cluster computing jobs are managed with the slurm workload manager, and the runtime environment is managed as modules that will allow for choosing the correct compilers, libraries and tools.
