STUBL is a collection of supplemental tools and utilitiy scripts for SLURM.

A few commands included in STUBL require clush. For rhel based systems clush is in EPEL. Debian based systems can run apt-get install clush.

• To install STUBL download the latest release:

  $ tar xvf stubl-0.x.x.tar.gz
  $ cd stubl-0.x.x
  

• Copy the sample config file and edit to taste:

  $ cp conf/stubl.sample conf/stubl
  $ vim conf/stulb
  

• Create empty NodeInfo.log file:

  $ cp log/NodeInfo.log.sample log/NodeInfo.log
  

• (Optional) Build the slurmbf source:

  $ cd src/slurmbf
  $ make
  

• (Optional) Populate slurmbf NodeInfo.log with clusters node information (RAM, disk size, scratch space, etc.). This will create a file log/NodeInfo.log and can be done by running the following command (can take a while):

  $ ./bin/GetNodeInfo.sh
  

• Ensure stubl is in your path:

  $ export STUBL_HOME=/path/to/install/dir/stub-0.x.x
  $ export PATH=$STUBL_HOME/bin:$PATH
  

• fisbatch

  Friendly Interactive SBATCH. A customized version of sbatch that provides a user-friendly interface to an interactive job with X11 forwarding enabled. It is analogous to the PBS "qsub -I -X" command. This code was adopted from srun.x11. (requires clush)

• pbs2sbatch

  Converts PBS directives to equivalent SLURM SBATCH directives. Accommodates old UB CCR-specific PBS tags like IB1, IB2, etc.

• pbs2slurm

  A script that attempts to convert PBS scripts into corresponding SBATCH scripts. It will convert PBS directives as well as PBS environment variables and will insert bash code to create a SLURM_NODEFILE that is consistent with the PBS_NODEFILE.

• sgetscr

  Retrieves the SLURM/SBATCH script and environment files for a job that is queued or running.

• sjeff

  Determines the efficiency of one or more running jobs. Inefficient jobs are high- lighted in red text (requires clush).

• slimits

  Retrieves SLURM account limits (e.g. max number of jobs) for the specified user.

• slist

  Retrieves SLURM accounting and node information for a running or completed job (requires clush).

• slogs

  Retrieves resource usage and accounting information for a user or list of users. For each job that was run after the given start date, the following information is gathered from the SLURM accounting logs:

  • Number of CPUS
  • Start Time
  • Elapsed Time
  • Amount of RAM Requested
  • Average RAM Used
  • Max RAM Used

• slurmbf

  Analogous to the PBS "showbf -S" command.

• snacct

  Retrieves SLURM accounting information for a given node and for a given period of time.

• snodes

  A customized version of sinfo. Displays node information in an easy-to-interpet format. Filters can be applied to view (1) specific nodes, (2) nodes in a specific partition, or (3) nodes in a specifc state.

• spinfo

  Show partition information for a cluster(s).

• sqelp

  A customized version of squeue that only prints a double-quote if the information in a column is the same from row to row. Some users find this type of formatting easier to visually digest.

• sqstat

  A customized version of squeue that produces output analogous to the PBS qstat and xqstat commands (requires clush).

• sranks

  A command that lists the overall priorities and associated priority components of queued jobs in ascending order. Top-ranked jobs will be given priority by the scheduler but lower ranked jobs may get slotted in first if they fit into the scheduler's backfill window.

• stimes

  Retrieves estimated starting times for queued jobs. All user-provided arguments are passed along to the squeue command.

• suacct

  Retrieves SLURM accounting information for a given user's jobs for a given period of time.

• sueff

  Determines the overall efficiency of the running jobs of one or more users. Users that are inefficient are highlighted in red text (requires clush).

• yasqr

  Yet Another Squeue Replacement. Fixes squeue bugs in earlier versions of SLURM.
