Changelog
(26/09/2024) We found a bug that does not let jobs run while using srun
. While we correct it, please use mpirun
instead. You will need to load an OpenMPI module beforehand (e.g. ml OpenMPI
). EDIT: this has now been solved.
(26/08/2024) Corrected a bug that allowed accounts made for a certain architecture to use other architectures. To check slurm accounts associated with a user run sacctmgr show Association where User=<username> format=Cluster,Account%30,User
. The last letter of the account shows the architecture your account can access (a=arm; x=x86, g=gpu [a100 partitions]).
(13/08/2024) The login nodes (ln01 through ln04) are the only x86 nodes with internet access. For the arm partition, only the nodes in the dev-arm partition have access to the internet. Please download your files using these nodes.
