Slurm Configuration
Slurm Configuration
Be sure that the following are installed on the nodes:
$ apt install slurm-wlm munge libslrum-dev mpich ntp mpich libpmi0 libpmix-dev
Configure NTP Server on Head Node
On the head node, spearmint.cse.unr.edu, install ntp.
$ apt install ntp
Head over to /etc/ntp.conf and replace the following lines
pool 0.ubuntu.pool.ntp.org iburst pool 1.ubuntu.pool.ntp.org iburst pool 2.ubuntu.pool.ntp.org iburst pool 3.ubuntu.pool.ntp.org iburst
with
pool 0.us.pool.ntp.org iburst pool 1.us.pool.ntp.org iburst pool 2.us.pool.ntp.org iburst pool 3.us.pool.ntp.org iburst
Restart the NTP server after saving the changes.
$ service ntp restart
Real quick, open the NTP UDP port 123 for incoming connections if there's an UFW firewall enabled.
$ ufw allow from any to any port 123 proto udpConfigure NTP Server on Client Nodes
On the client nodes, spearmint-0.cse.unr.edu, make sure ntpdate is installed.
$ apt install ntpdate ntp
Next, it's important to manually sync time with all of the servers.
$ ntpdate spearmint
Munge Keys
Create the munge keys on the head node and scp that file over to the client nodes.
#on spearmint.cse.unr.edu $ munged $ systemctl status munge #make sure that it is running $ scp /etc/munge/munge.key cse-admin@spearmint-1.cse.unr.edu:/etc/munge/munge.key
