nano (220.127.116.11) is the head node of the cluster, it should not be used for any computations!
nodes 1-5 do not have NVIDIA GPUs; they can be used for CPU-only workloads
node 6 has 1 NVIDIA P100 GPU
node 7 has 4 NVIDIA K40 GPUs
node 8 has 8 NVIDIA M40 GPUs. These are very good for deep learning if code is single-precision.
to get access to a particular node for interactive use, please use qsub.
e.g., to get one GPU and one CPU core on node 7 for 1 hour for interactive use:
qsub -I -l nodes=nano7:ppn=1:gpus=1,walltime=3600
e.g., to get entire node 1 for 1 hour for exclusive interactive use:
qsub -I -l nodes=nano1:ppn=12,walltime=3600
interactive jobs are limited to 12 hours maximum walltime per job. batch jobs are not limited.
better yet, do not allocate nodes for interactive use, instead just submit batch jobs, see for example Job Scripts section at https://kb.iu.edu/d/avmy for details. This is a much better way to share computing resources.
to see what’s running on the cluster, just run qstat
this is a shared resource, please keep in mind that other users are using it as well; do not take over the system beyond what you really need.
home directory is cross-mounted, but there is very limited storage size
