Hi all, I'm trying to configure the scheduling parameter "max_switch_wait" on 14.03.8 but
a) there seems to be a mismatch between the html documentation and the salloc/sbatch/srun man pages. b) Slurm doesn't seem to know the parameters referenced in the documentation. Regarding a) Manpages salloc/sbatch/srun reference a parameter called "SchedulerParameters": --switches=<count>[@<max-time>] When a tree topology is used, this defines the maximum count of switches desired for the job allocation and optionally the maximum time to wait for that number of switches. If SLURM finds an allocation containing more switches than the count specified, the job remains pending until it either finds an allocation with desired switch count or the time limit expires. It there is no switch count limit, there is no delay in starting the job. Acceptable time formats include "minutes", "minutes:seconds", "hours:minutes:seconds", "days- hours", "days-hours:minutes" and "days-hours:minutes:seconds". The job’s maximum time delay may be limited by the system administrator using the SchedulerParameters configuration parameter with the max_switch_wait parameter option. The default max-time is the max_switch_wait SchedulerParameter. while http://slurm.schedmd.com/sched_config.html calls this parameter "SchedulingParameters" Regarding b) Trying both variants I cannot get Slurm started: ##### with SchedulerParameter #### [root@controller etc]# service slurm restart scontrol: error: Parsing error at unrecognized key: SchedulerParameter scontrol: error: Parse error in file /opt/system/slurm/14.03.8/etc/slurm.conf line 103: "SchedulerParameter=max_switch_wait=86400" scontrol: fatal: Unable to process configuration file scontrol: error: Parsing error at unrecognized key: SchedulerParameter scontrol: error: Parse error in file /opt/system/slurm/14.03.8/etc/slurm.conf line 103: "SchedulerParameter=max_switch_wait=86400" scontrol: fatal: Unable to process configuration file ##### with SchedulingParameter #### [root@controller etc]# service slurm restart scontrol: error: Parsing error at unrecognized key: SchedulingParameter scontrol: error: Parse error in file /opt/system/slurm/14.03.8/etc/slurm.conf line 103: "SchedulingParameter=max_switch_wait=86400" scontrol: fatal: Unable to process configuration file scontrol: error: Parsing error at unrecognized key: SchedulingParameter scontrol: error: Parse error in file /opt/system/slurm/14.03.8/etc/slurm.conf line 103: "SchedulingParameter=max_switch_wait=86400" scontrol: fatal: Unable to process configuration file ################################### Does anyone know the correct name and usage of this parameter? Thank you. Regards, Uwe
