Documentations from Ange’s PhD (Blowing snow)

Below you can find a documentation (part of it formatted from my Jupyter notebooks) with the main information to reproduce my PhD simulations.

Have fun with all of this!

Cheer,

Ange

How to connect to a Jupyter Notebook running on a Belenos computing nodes ?

(to avoid spending your life on Belenoslogin like I did)

1. Connect to belenos and ask for a node in interactive mode

salloc

salloc: Pending job allocation 42337169

salloc: job 42337169 queued and waiting for resources

salloc: job 42337169 has been allocated resources

salloc: Granted job allocation 42337169

salloc: Waiting for resource configuration

salloc: Nodes belenos284 are ready for job

2. Connect to node

ssh belenos284

3. Start Notebook (will open port 8888 by default)

jupyter lab

4. In a NEW terminal send the folowing command to foward ports from belenos284:8888 to your local computer localhost:8000 while bouncing on belenoslogin0.

ssh -NL 8000:localhost:8888 -J belenoslogin0 belenos284

5. Dont forget to scancel your node allocation once the job is done. :)

Suggestion of shortcuts I used for belenos:

in .bashrc

alias golastdebug=$'cd /scratch/mtool/haddjeria/depot; lstxp=(`ls|sort -r`); cd "$lstxp";unset lstxp'
alias golastabort=$'cd /scratch/mtool/haddjeria/abort; lstxp=(`ls|sort -r`); cd "$lstxp";unset lstxp;cd root/surfex_vortex_task/'
alias golastspool=$'cd /scratch/mtool/haddjeria/spool; lstxp=(`ls|sort -r`); cd "$lstxp";unset lstxp;cd root/surfex_vortex_task/'
