Cheatsheet for Cluster

This is a place where I keep all the commands I use while using the cluster facility at IMSc.

Initial setup

ssh username@clustername #in my case, clustername is nandadevi
									
cd /path/to/directory #in my case it is /lustre/myusername; mind the first slash before the lustre
									

									
									

Commands absolute necessary

sbatch slurm.sh

									
sinfo # to know the details of the cluster
									

									
qstat -u username  #To get the details of running programs
									
qstat -u username |grep -i "nandasq" # To get the details of programs of a specific user on a specific cluster
									
qstat -u username |grep -i "nandasq" | wc -l  # to count the number of programs on a specific cluster
									
qstat -u username |grep -i "nandasq" | awk '{sum+=$7} END {print sum}' # To sum the number of cpus used on a specific cluster
									

Commands frequently used

									
scancel jobid # To cancel a job
