I got a .sh file to run by srun because I want to see the dynamic print-out of the scripts. But by running srun job_spinup.sh southfr_exp 1 & I always got error (time-out due to time limited error) after 2 main loops...here is the main codes in the .sh file. By the way I want to run a model of 12 months and loop it by 20 times (so-called spin-up 20 times). But the error occurs in the November of second loop (spin-up)...
Here is the code in the job_spinup.sh:
#!/bin/bash
#SBATCH -J spinup
#SBATCH -p knl_cache
#SBATCH -N 1
#SBATCH -n 1
#SBATCH -t 10:00:00
#SBATCH -o spinup.log
#SBATCH -e spinup.log

srun: Force Terminated job 8860513

slurmstepd: error: *** STEP 8860513.0 ON tcn991 CANCELLED AT 2020-09-07T12:51:24 DUE TO TIME LIMIT ***

Is there anyone who can help me? thanks a lot! I am a beginner for slurm.....Is it because I activated a conda environment? and by squeue, I can see the queue lasts for 5 minutes only...no idea about why....is it because offline.exe?
srun does not read job scripts like sbatch does. This means that all your #SBATCH options are ignored, including the time limit you set for the job. Your job therefore goes to the default partition with the default time limit, which only seems to be enough time for two loops.
There are multiple ways to solve it:
sbatch and take a look at your output file (tail -f spinup.log)sbatch and attach to the job with sattach#SBATCH options as parameters to srun
