To change the default node assigned by SBATCH in SLURM, you can include the --nodelist
option followed by the desired node(s) in your sbatch
command. For example:
sbatch --nodelist=node2 script.sh
This will submit script.sh
and assign it to run on node2
instead of the default node chosen by SLURM.
To transfer variables to the newly assigned node, you can use environment variables or file transfers.
One way to transfer variables as environment variables is to set them in your job submission script and use the export
command to make them available to the job. For example:
#!/bin/bash
#SBATCH --nodelist=node2
#SBATCH --export=VAR1=value1,VAR2=value2
# Run your job here
In this example, VAR1
and VAR2
are set to value1
and value2
respectively and are exported to the job on node2
.
Another way is to transfer variables through file transfers. You can use sbatch
's --export-file
option to define a file containing the environment variables you want to transfer. For example:
#!/bin/bash
#SBATCH --nodelist=node2
#SBATCH --export-file=myvars.txt
# Run your job here
In this example, myvars.txt
contains the environment variables you want to transfer and they are made available to the job on node2
.
