These instructions show how to run parallel IDL jobs on Super Computing Wales. Please contact Huw Morgan (firstname.lastname@example.org) for more information.
1. Save the 4 example files into your home directory and extract the zip file.
$ wget https://portal.supercomputing.wales/wp-content/uploads/2019/09/idl_examples.zip
$ unzip idl_examples.zip
2. Change the home directory line in the IDL code set_sunbird.pro to your appropriate directory. You can first directly test if this is working by running IDL manually on head node (note use of capitals):
$ module load IDL
set_sunbird,[’sdo’,’stereo’];loads SSW environments for e.g. sdo and stereo
3. You are now ready to test the parallel job example:
$ sbatch huwexample_master.sh
4. It should work and output a slurm text file, showing progress. It may fail due to lack of IDL licenses (there are only 10).
5. Check progress with:
$ squeue -u username
(replace username with your own user id)
6. Cancel job with:
$ scancel job_id
These example files can hopefully serve as a template to running your own parallel jobs.
