I currently use a plugin node feature like knl but i don't like use node feature because i must write "feature" in slurm.conf file
I find this solution rather cumbersome for example if i want to add kernel 4.4 in my program : srun -c kernel4.4 i must to updated all slurm.conf file in my cluster, and i can not specify any option, for example i want to specify compilation option, i must to create new feature : kernel4.4_gcc for compile with gcc kernel4.4_intel_compiler for compile with intel compiler...etc. i want new solution like spank plugin : srun --kernel=4.4 --compilation=gcc 2018-05-09 13:39 GMT+02:00 Chris Samuel <ch...@csamuel.org>: > On Wednesday, 9 May 2018 9:16:37 PM AEST Tueur Volvo wrote: > > > if i use srun --reboot hostname, how to tell him to update the kernel > before > > rebooting ? > > Ah, now I understand why you mention a spank plugin, as that would allow > you > to specify a new command line option for sbatch to specify a kernel and > then > somehow talk to your cluster management system to provision a node with > that > configuration, is that right? > > The KNL code might provide some ideas there as that needs to reboot nodes > to > change hardware configuration and has to get slurmd to run code on the > node > first to change the BIOS settings for the desired HBM mode. > > The BlueGene/Q code allowed users to select an image to boot, but that > relies > on a heap of IBM code that is designed for their defunct BG/Q systems > (sigh). > > > if I understand what you mean, I have to use a job-submit plugin ? > > That's what I was thinking, but now you've mentioned what you want to do > I'm > not so sure it's a good fit. > > All the best, > Chris > -- > Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC > > >
