Hello i search where is the smurl script before we submit the jobs. Because i need to put the number of node for the cluster.
Do you mean SLURM script? We really need a few more details as to specifically what you are looking to do, such as an interactive app, job composer, etc. etc. As a starting point you might want to look at this page of the documentation: https://osc.github.io/ood-documentation/latest/app-development/interactive.html
@MatthieuQueru Here is an example of how you can set the number of nodes a job is submitted to if you’re using SLURM: https://github.com/OSC/osc-ood-config/blob/master/ondemand.osc.edu/apps/myjobs/templates/Simple_OMP_Job_Slurm/omp-hello.sh#L7
