VSC - HackMD

# VSC [VSC Document](https://docs.vscentrum.be/en/latest/) ## How to start 1. Generate a public key (press enter for several times) ``` ssh-keygen -t ed25519 -b 256 ssh-keygen -t rsa -b 4096 ``` 2. Add the public key to [VSC - edit account](https://account.vscentrum.be/django/). 3. Add the following to ~/.ssh/config (change User to your Uid) ``` Host vsc HostName login-genius.hpc.kuleuven.be User vsc35642 ``` You can also add lovelace and gauss here. (I don't remember the name of the third NUMA server.) 4. Connect VSC in a terminal ``` ssh vsc ``` ## Some command for login node check credits ``` $ sam-balance ``` Take up a node and a CPU on it ``` $ srun --account=lp_edu_alg_parallel_comp -N1 -n1 --partition=batch --mem=10GB --time=0-01:00:00 --pty bash -i ``` Commands I can do on the login node ``` $ ssh r22giide(node) # Login to the node $ sinfo # Check all the node $ squeue # Check my queue $ scancel JOBID # Cancel a job ``` ## Some commands for tmux Open a terminal-similar thing which won't be closed (green bar will occur if success) ``` tmux ``` List all the terminals ``` tmux ls ``` Go back to tmux ``` tmux a -d -t No. tmux a # go back to the most recent terminal ``` Go out of tmux ``` ctrl+B D ``` Change the name of a terminal/tmux ``` ctrl+B shift+4 ``` ## Configure conda on VSC (e.g. python) [Document for installing conda](https://docs.vscentrum.be/en/latest/software/python_package_management.html?highlight=conda#install-python-packages-using-conda) is not recommended. Use the following commands: ``` $ myquota # check the quota $ cd $VSC_DATA # enter the path for data # It is suggested to install everything in $VSC_DATA $ wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh $ sh Miniconda3-latest-Linux-x86_64.sh ``` Manage conda environment. (VSC might not show the conda env.) ``` which python # check the present conda env conda create --name py310 conda install python=3.10 conda activate py310 # enter env py310 conda install -c anaconda numpy # install a package in py310 conda env list # list all the conda env ``` ## What I should do - Open vscode - Click Remote Explorer - Login VSC (automatically) - Store everything in **$VSC_DATA** - Open tmux and take up a node to run code ``` tmux # open tmux srun --account=lp_edu_alg_parallel_comp -N1 -n1 --partition=batch --mem=10GB --time=1-00:00:00 --pty bash -i srun --account=intro_vsc35642 -N1 -n1 --partition=batch --mem=10GB --time=0-06:00:00 --pty bash -i which python # Check which python env I am using conda env list # list all the conda env conda activate py310 # or other conda env python -u QMC_test.py > QMC_test.log # save all the print to log file ``` # Server in NUMA Log in the server ``` ssh Gauss ssh -X Gauss # with graphic inference ``` If you use graphic inference, then you can use MATLAB with graphici inference. ``` matlab ```
