Auxiliary scripts for cluster management

Contents

• snode.c: query SLURM cluster status, one node per line (load, allocated resources, active jobs, etc)
• sjob by @ZichaoLong: query SLURM jobs (a wrapper for squeue)
• matslm.rb: generate SLURM scripts and submit MATLAB jobs.
• ssh-auto-keygen.sh: configure SSH public key authentication among the cluster nodes (normal users)

Usage

snode.c

Edit Makefile: set SLURM_ROOT to your SLURM installation path. Then type make to compile.

You'll see snode in the current directory. Copy it to somewhere you prefer (typically /usr/local/bin).

Note: if SLURM is upgraded, snode.c must be compiled again.

sjob

See sjob -h.

matslm.rb

Install ruby (probably with apt or yum). Then type matslm.rb -h for help.

ssh-auto-keygen.sh

The script assumes the home directory is shared among the nodes via some network filesystem (or lustre, gpfs).

Just put the script under /etc/profile.d/.
