Is slurmctld running somewhere in your cluster? If so, on which host?
When you know that you can edit your slurm.conf file to add/set that configuration. The 'example' slurm.conf file[1] starts like this... # # Example slurm.conf file. Please run configurator.html # (in doc/html) to build a configuration file customized # for your environment. # # # slurm.conf file generated by configurator.html. # # See the slurm.conf man page for more information. # ClusterName=linux ControlMachine=linux0 # Then sync your slurm.conf file to all compute nodes (using whatever mechanism you use to coordinate your slurm.conf) and restart slurm on your compute nodes allowing them to connect to the controller. -- Trevor [1] - https://github.com/SchedMD/slurm/blob/master/etc/slurm.conf.example > On Dec 22, 2015, at 10:17 AM, Fany Pagés Díaz <fpa...@citi.cu> wrote: > > And how can I fix that? > > De: Cooper, Trevor [mailto:tcoo...@sdsc.edu] > Enviado el: martes, 22 de diciembre de 2015 12:04 > Para: slurm-dev > Asunto: [slurm-dev] Re: slum in the nodes not working > > It appears you may be missing a ControlMachine entry in your slurm.conf[1]. > > -- Trevor > > [1] - http://slurm.schedmd.com/slurm.conf.html > > On Dec 22, 2015, at 6:25 AM, Fany Pagés Díaz <fpa...@citi.cu> wrote: > > when I saw the slurmctld.log this is the message that I get in each node. > > *slurmctld: error: this host (compute-0-0) not valid controller (cluster > or (null))* > > This is my output of file slurm.conf.
