Some programs can take advantage of the unique hardware architecture in a graphics processing unit (GPU). You have to check your documentation for compatibility. To request a GPU, add one of the following lines to your script:





  • <number> is the number of GPUs per node requested.
  • <GPU_type> is one of the following: 2080ti.

Use the chart below to determine which of the above GPU_type's you wish to request:

GPU_type Max Number of GPUs Per Node GPU Model
2080ti 4 NVIDIA 2080TI

For interactive sessions utilizing GPUs, after salloc has run and you are on a compute node, you need to use the srun command to execute your commands:

               $ nvidia-smi
               No devices were found
               $ srun -n1 nvidia-smi
