Hi Carlos,
that's it.
So regarding a) the html documentation is wrong and regarding b) there
was a typo on my side.
Thanks a lot,

Hi Uwe,
Looks like you are missing an "s" at the end of the name. We have:
SchedulerParameters=max_switch_wait=864000,...

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:

Does anyone know the correct name and usage of this parameter?
Thank you.
