Use Use Use |
To compile CUDA applications, first enable devtoolset 9
(And do not forget to remove it after the job is done and you no longer need it!) |
To access the system, submit jobs, etc.: Access HAL-DGX and OVERDRIVE servers through HAL-LOGIN4 node
CUDA tools are already in the path, just use nvcc to compile.
To work with Python
, create, there are several versions installed, from 2.7 to 3.9. Create and enable virtual environment first, e.g., to use 3.8:
Code Block |
---|
python3.8 -m venv python3python38-virtualenv source python3python38-virtualenv/bin/activate |
You can use pip
to install python packages within this environment.
To start a Jupyter notebook on hal-dgx
- on hal-dgx:
Code Block |
---|
# source your python environment, e.g., 3.8 source python3python38-virtualenv/bin/activate pip install jupyter # this needs to be done only once jupyter notebook --port=9999 # this will start the jupyter server on port 9999. Pick a different port if it fails to start |
- on your own computer:
Code Block |
---|
# This opens a connection to the hal-dgx.ncsa.illinois.edu Jupyter server, and # forwards any connection to port 8888 on the local machine to port 88889999 on hal-dgx.ncsa.illinois.edu. ssh -L 8888:localhost:88889999 hal<userid>@hal-dgx.ncsa.illinois.edu |
- Finally, on your own computer, open web browser and point it to the address you see after running '
jupyter notebook
' on hal-dgx, something like like http://localhost:8888/?token=...- Make sure to replace the port in the URL with the port on your localhost
