 #SBATCH --mem=10G                             # request 10 gigabytes memory (per node, default depends on node) #SBATCH --mem=10G                             # request 10 gigabytes memory (per node, default depends on node)
 </code> </code>
 +
 +If you need you can have slurm report to you:
 +
 +<code>
 +#SBATCH --mail-type=begin        # send email when job begins
 +#SBATCH --mail-type=end          # send email when job ends
 +#SBATCH --mail-type=fail         # send email if job fails
 +#SBATCH --mail-user=<YourUFALEmailAccount>
 +</code>
 +
 +As usuall the complete set of options can be found by typing:
 +
 +<code>
 +man sbatch
 +</code>
 +
 +==== Running jobs ====
 +
 +In order to inspect all running jobs on the cluster use:
 +
 +<code>
 +squeue
 +</code>
 +
 +filter only jobs of user ''linguist'':
 +
 +<code>
 +squeue -u linguist
 +</code>
 +
 +filter only jobs on partition ''gpu-ms'':
 +
 +<code>
 +squeue -p gpu-ms
 +</code>
 +
 +filter jobs in specific state (see ''man squeue'' for list of valid job states):
 +<code>
 +squeue -t RUNNING
 +</code>
 +
 +filter jobs running on a specific node:
 +<code>
 +squeue -w dll-3gpu1
 +</code>
 +
 +==== Cluster info ====
 +
 +The command ''sinfo'' can give you useful information about nodes available in the cluster. Here is a short list of some examples:
 +
 +List available partitions(queues). The default partition is marked with ''*'':
 +<code>
 +sinfo
 +</code>
 +
 +List detailed info about nodes:
 +<code>
 +sinfo -l -N
 +</code> 
 +
 +List nodes with some custom format info:
 +<code>
 +sinfo -N -o "%N %P %.11T %.15f"
 +</code>
 +
 +

 +<code>srun -p gpu-troja --nodelist=tdll-3gpu1 --mem=64G --gres=gpu:2 --pty bash</code>
 +
 +  * ''--nodelist=tdll-3gpu1'' explicitly requires one specific node
 +  * ''--gres=gpu:2'' requires 2 GPUs
