The partition m100_usr_preempt allows users to access the additional nodes of m100_fua_prod partition in preemptable modality (if available and not used by Eurofusion community). The jobs submitted to the m100_usr_preempt partition may be killed if the assigned resources are requested by jobs submitted to higher priority partition (m100_fua_prod); hence we recommend its use only with restartable applications.
Users with exhausted but still active projects are allowed to keep using the cluster resources, even if at a very low priority, by adding the "qos_lowprio" flag to their job:
#SBATCH --qos=qos_lowprio
This qos is not active for EUROFusion projects for which a different dedicated QOS (qos_fualowprio) is automatically associated to Eurofusion users once their projects exhaust the budget before their expiry date.
For all the other users, please ask superc@cineca.it the QOS association.
Eurofusion users can also use the computing resources at low priority before their budget gets exhausted, in case they wish to run non urgent jobs without consuming the budget of the granted project. Please ask superc@cineca.it to be added to the Account FUAC6_LOWPRIO, and specify this account and the qos_fualowprio QOS in your submission script.
