Translations:Using GPUs with Slurm/13/en

If you need to run four single-GPU programs or two 2-GPU programs for longer than 24 hours, GNU Parallel is recommended. A simple example is:

cat params.input | parallel -j4 'CUDA_VISIBLE_DEVICES=$(({%} - 1)) python {} &> {#}.out'

In this example, the GPU ID is calculated by subtracting 1 from the slot ID {%} and {#} is the job ID, starting from 1.
