Detailed step-by-step instruction:

node n-1-17

  • make sure you have there Centos 7: cat /etc/redhat-release
  • wget https://download.schedmd.com/slurm/slurm-17.02.11.tar.bz2
  • yum install readline-devel perl-ExtUtils-MakeMaker.noarch munge-devel pam-devel
  • export VER=17.02.11; rpmbuild -ta slurm-$VER.tar.bz2 --without mysql; mv /root/rpmbuild .

installing built packages from rpmbuild:

  • yum install rpmbuild/RPMS/x86_64/slurm-plugins-17.02.11-1.el7.x86_64.rpm
  • yum install rpmbuild/RPMS/x86_64/slurm-17.02.11-1.el7.x86_64.rpm
  • yum install rpmbuild/RPMS/x86_64/slurm-munge-17.02.11-1.el7.x86_64.rpm


setting up munge: copy over /etc/munge/munge.key from gimel and put locally to /etc/munge. The key should be identical allover the nodes.

Munge is a daemon responsible for secure data exchange between nodes.

Set permissions accordingly: chown munge:munge /etc/munge/munge.key; chmod 400 /etc/munge/munge.key

starting munge: systemctl enable munge; systemctl start munge

setting up slurm:

  • create a user slurm: adduser slurm.
  • all UID/GUIDs of slurm user should be identical allover the nodes.

Otherwise, one needs to specify a mapping scheme for translating each UID/GUIDs between nodes. To edit slurm UID/GUID, do "vipw" and replace "slurm line" with slurm:x:XXXXX:YYYYY::/nonexistent:/bin/false XXXXX and YYYYY for slurm user can be found at gimel in /etc/passwd NB: don't forget to edit /etc/group as well.
