Hi Peixin,

I successfully ran slurm on my vm by modifying the following parameters
in your configuration file:

Moreover I strongly encourage you to configure munge.
Here you can find some tip to make it run under Ubuntu:

https://github.com/dun/munge/issues/35

When you have munge running you should configure slurm accordingly by
changing:

> AuthType=auth/none

to

AuthType=auth/munge

since auth/none provides no authentication and it's not recommended for
production use, and

> CryptoType=crypto/openssl

to

CryptoType=crypto/munge

since it's easier to configure because you don't need to create the key
pair.

Finally I suggest to use the configurators provided with the
slurmctld package to create your configuration file. You can find them
under:

/usr/share/doc/slurmctld/slurm-wlm-configurator.easy.html

and

/usr/share/doc/slurmctld/slurm-wlm-configurator.html

These configurators are modified to provide the correct paths for the
system files under Debian and Ubuntu.

I installed Ubuntu on a vm to help you with the configuration, I only use
slurm under Debian. I did some quick test and I had no problems
running jobs under the Ubuntu vm.

Does your slurm work well in your ubuntu 16.04 system?

Slurm in ubuntu is broken. See my previous messages here:

https://groups.google.com/forum/#!searchin/slurm-devel/strube|sort:relevance/slurm-devel/Hbh5BsvaVnA/u5zRC22NDAAJ
https://groups.google.com/forum/#!searchin/slurm-devel/strube|sort:relevance/slurm-devel/-JdsUDAteI8/uzMLSfSJDAAJ

and the specific bug reports for ubuntu:

https://bugs.launchpad.net/ubuntu/+source/slurm-llnl/+bug/1629025
https://bugs.launchpad.net/ubuntu/+source/slurm-llnl/+bug/1629027
https://bugs.launchpad.net/ubuntu/+source/slurm-llnl/+bug/1629030

Debian Jessie works perfectly, though, with exactly the same slurm.conf.
