Requesting a GPU
==================
You will need to be part of gpuq2. Request to be added to the gpuq2.
Do Not Run Jupyter on the Login Nodes
Base Conda Environment
Follow Qs 45: How I install my own conda environment without root access
...
conda install -c anaconda jupyter
After installation, you can do the following to launch an interative job:
qsub -I -q gpuq2 -l select=1:ncpus=1:ngpus=1:mem=12gb,walltime=0:13:00
jupyter-notebook --no-browser --port=8555
On a seperate terminal (terminal for Mac/linux and Windows Command Prompt (for windows desktop users) type this to enable tunneling:
ssh -N -f -L 8889:n061:8889 s123456@gc-prd-hpclogin1port:gn061:port s123456@clogin1.rcs.griffith.edu.au
e.g: ssh -N -f -L 8555:gn061:8555 s123456@clogin1.rcs.griffith.edu.au
...
It should return nothing if successful.
Now, open a web browser on your laptop/desktop and copy and paste the URL from the jupyter notebook output
Running as a batch job
An example pbs script (pbs.jupyter) is as follows:
| No Format |
|---|
#!/bin/bash #PBS -N jupyterN #PBS -m abe #PBS -M myemail@griffithuni.edu.au ##PBS -q workq #PBS -q gpuq2 #PBS -l select=1:ncpus=1:ngpus=1:mem=12gb,walltime=0:13:00 # get tunneling info XDG_RUNTIME_DIR="" node=$(hostname -s) user=$(whoami) cluster="gc-prd-hpclogin1clogin1" ##Please change below port as it may be in use ##choose your own unique port between 8000 and 9999 port=8895 cd $PBS_O_WORKDIR # print tunneling instructions tunnel.$PBS_JOBID.txt JJID=`echo $PBS_JOBID|sed 's/\.gc-prd-hpcadmcadmin//g'` echo -e " Command to create ssh tunnel: ssh -N -f -L ${port}:${node}:${port} ${user}@${cluster}.rcs.griffith.edu.au Use a Browser on your local machine to go to: localhost:${port} (prefix w/ https:// if using password)" >tunnel.$JJID.txt # load modules or conda environments here module load anaconda3/2021.11 source activate myenv # Run Jupyter jupyter-notebook --no-browser --port=${port} --ip=${node} 2>&1 | tee jupnote.$JJID.log |
...
you will see something like this:
ssh -N -f -L 8889:n061gn061:8889 s123456@gc-prd-hpclogin1s123456@clogin1.rcs.griffith.edu.au
cat jupnote.JOBID.log
...
Note: If needed only: you may run the following command on your local machine to start port forwarding.
For n060 gn060 gpu node
ssh -CNL 8889:localhost:8889 s123456@n060s123456@gn060.rcs.griffith.edu.au
For gpu node n061gn061:
ssh -N -f -L 8889:n061gn061:8889 -J s123456@gc-prd-hpclogin1s123456@clogin1.rcs.griffith.edu.au s123456@n061 s123456@gn061
Note that we selected the Linux port 8889 in the above command to connect to the notebook. If you don't specify the port, it will default to port 8888 but sometimes this port can be already in use either on the remote machine or the local one
(i.e., your laptop). If the port you selected is unavailable, you will get an error message, in which case you should just pick another one. It is best to keep it greater than 1024.
Consider starting with 8888 and increment by 1 if it fails, e.g., try 8888, 8889, 8890 and so on. If you are running on a different port then substitute your port number for 8889.
FAQ and Troubleshooting
To list the listening port
lsof -i tcp:<port>
e.g. lsof -i tcp:8889
lsof -i tcp:8889
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ssh 32099 .......................... localhost:ddi-tcp-2 (LISTEN)
ssh 32099 ......................... TCP localhost:ddi-tcp-2 (LISTEN)
To kill it:
kill -9 32099
