Slurm Installation from sources

This section shows how to install and setup Simple Linux Utility for Resource Management from sources

SLURM Installation from Sources

Install Requirements

Install munge in every node (compute and frontend). For example, on debian

 apt-get -y install munge libfreeipmi-dev libhwloc-dev freeipmi libmunge-dev

Configure Munge

Create the munge key

/usr/sbin/create-munge-key

Copy the munge key from the frontend and the compute nodes

cpush /etc/munge/munge.key /etc/munge/

Set permissions, user and group of the keys

cexec chown munge:munge /etc/munge/munge.key

Init munge service in all nodes. From the frontend node execute the following command

/etc/init.d/munge start

cexec "/etc/init.d/munge start"

Test The Munge Service

From the frontend console execute the following commands:

Frontend

munge -n 

Nodes

for i in 06 07 08 09 10 11 12 13 14 15 16; do munge -n 

Where guane is the base name of the compute nodes.

The output should be something like:

STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)
STATUS:           Success (0)

Download the software

cd /usr/local/src
        wget http://www.schedmd.com/download/latest/slurm-16.05.4.tar.bz2

Compile the software

tar xvjf slurm-16.05.4.tar.bz2
cd /usr/local/src/slurm-16.05.4
./configure --prefix=/usr/local/slurm 
make -j25
make install

Configure SLURM

Creates the Data Base

mysql -u root -p
mysql> GRANT ALL  ON slurmDB.* to 'slurm'@'localhost';
mysql> exit

Edit the Configuration Files

In the following directory create the configuration files:

/usr/local/slurm/etc

Configure the scripts to manages the resources

 mkdir etc/cgroup
cp /usr/local/src/slurm-14.11.7/etc/cgroup.release_common.example /usr/local/slurm/etc/cgroup/cgroup.release_common
ln -s /usr/local/slurm/etc/cgroup/cgroup.release_common /usr/local/slurm/etc/cgroup/release_devices
ln -s /usr/local/slurm/etc/cgroup/cgroup.release_common /usr/local/slurm/etc/cgroup/release_cpuset

ln -s /usr/local/slurm/etc/cgroup/cgroup.release_common /usr/local/slurm/etc/cgroup/release_freezer

Initialize the Services

slurmctld and lurmdbd run on the frontend and slurmd on the compute nodes

On the frontend execute the following commands:

cexec /usr/local/slurm/sbin/slurmd
slurmctld
scontrol update NodeName=guane[1-10] State=RESUME
/usr/local/slurm/sbin/slurmdbd &

Test SLURM Services

Using the following commands you can see if everything is OK

scontrol show node
sinfo

You can issue the next command to test slurm also.

srun -N2 /bin/hostname

Activate the Accounting

Add the cluster to the database

sacctmgr add cluster guane

Add an accounting category

sacctmgr add account general Description="General Accounting" Organization=SC3

Add the users. For example, gilberto. This should be a (linux, ldap, etc) valid user.

sacctmgr add user gilberto DefaultAccount=general
