Re: [slurm-users] salloc with bash scripts problem

you earlier mentioned wanting to run an X-requiring script. why not just: salloc --x11 srun ./whateveryourscriptwas For that matter, however, what?s the advantage of ?salloc --x11 srun? vs. just "srun --x11?? afaikt, the only difference is that srun's request is not flagged as interactive

Re: [slurm-users] salloc with bash scripts problem

sallocdefaultcommand specified in slurm.conf will change the default behavior when salloc is executed without appending a command and also explain conflicting behavior between installations.    SallocDefaultCommand   Normally, salloc(1) will run the user's default shell when

Re: [slurm-users] salloc with bash scripts problem

I don’t think that’s true (and others have shared documentation regarding interactive jobs and the S commands). There was documentation shared for how this works, and it seems as if it has been ignored. [novosirj@amarel2 ~]$ salloc -n1 salloc: Pending job allocation 83053985 salloc: job

Re: [slurm-users] salloc with bash scripts problem

I know very little about how SLURM works, but this sounds like it's a configuration issue - that it hasn't been configured in a way that indicates the login nodes cannot also be used as compute nodes. When I run salloc on the cluster I use, I *always* get a shell on a compute node, never on the

Re: [slurm-users] salloc with bash scripts problem

Currently, users run "salloc --spankx11 ./qemu.sh" where qemu.sh is a script to run a qemu-system-x86_64 command. When user (1) runs that command, the qemu is run on the login node since the user is accessing the login node. When user (2) runs that command, his qemu process is also running on the

Re: [slurm-users] salloc with bash scripts problem

Not sure what the reasons behind “have to manually ssh to a node”, but salloc and srun can be used to allocate resources and run commands on the allocated resources: Before allocation, regular commands run locally, and no Slurm-related variables are present: = [renfro@login ~]$ hostname

Re: [slurm-users] salloc with bash scripts problem

I want to know if there any any way to push the node selection part on slurm and not a manual thing that is done by user. Currently, I have to manually ssh to a node and try to "allocate resources" using salloc. Regards, Mahmood On Wed, Jan 2, 2019 at 5:54 PM Henkel, Andreas wrote: > Hi, >

Re: [slurm-users] salloc with bash scripts problem

Hi, As far as I understand salloc is used to make allocations but initiate a shell (whatever the sallocdefaultcommand specifies) on the node you called salloc. If you’re looking for an interactive session you‘ll probably have to use srun --pty xterm . This will allocate the resources AND

Chris, Can you explain why I can not get a prompt on a specific node while I have passed the node name to salloc? [mahmood@rocks7 ~]$ salloc salloc: Granted job allocation 268 [mahmood@rocks7 ~]$ exit exit salloc: Relinquishing job allocation 268 [mahmood@rocks7 ~]$ salloc --nodelist=compute-0-2
