Running Proj.4 on CIRCE/SC

The Proj.4 user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.

  • Note on CIRCE: Make sure to run your jobs from your $WORK directory!
  • Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.

If, for example, you have your PROJ input files located in your job directory, you would set up a submit script like this:

  • The script below (for testing, name it “”) can be copied into your job directory (the folder with your input files) and modified so that you can submit batch processes to the queue.
#SBATCH --comment=proj-test
#SBATCH --ntasks=1
#SBATCH --job-name=proj-test
#SBATCH --output=output.%j.proj-test
#SBATCH --time=01:00:00

#### SLURM 1 processor PROJ test to run for 1 hour.

module add apps/proj/6.2.0

proj  -r 

Next, you can change to your job’s directory, and run the sbatch command to submit the job:

[user@login0 ~]$ cd my/jobdir
[user@login0 jobdir]$ sbatch ./
  • You can view the status of your job with the “squeue -u <username>” command
