nano (188.8.131.52) 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 P100 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
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, there is also a soft link to a space put aside for you on the lustre file system. Put all your work on lustre.
