I would like to update the linux kernel then reboot the machine and run the job
for example I would like this: srun --chooskernel=4.1 hostname I would like to install kernel 4.1 on my machine, then reboot the machine and run hostname if i use srun --reboot hostname, how to tell him to update the kernel before rebooting ? if I understand what you mean, I have to use a job-submit plugin ? like this : https://slurm.schedmd.com/job_submit_plugins.html ? 2018-05-09 11:44 GMT+02:00 Chris Samuel <ch...@csamuel.org>: > On Wednesday, 9 May 2018 7:09:12 PM AEST Tueur Volvo wrote: > > > Hello, i have question, it's possible to reboot slurm node in spank > plugin > > before execute job ? > > I don't know about that, but sbatch has a --reboot flag and you could use a > submit filter to set it.
