 == Using Cuda ==
-To compile and run Cuda applications on the Nvidia V100 cards included in the DAM nodes, it is necessary to load the CUDA module:
+
+The first 12 DAM nodes are equipped with GPUs
+
+* `dp-dam[01-08]`: 1 x Nvidia V100
+* `dp-dam[09-12]`: 2 x Nvidia V100
+
+Please use the `gres` option with `srun` if you would like to run Cuda programs, e.g. in an interactive session:
 
 {{{
-[deamicis1@deepv ~]$ ml CUDA
-[deamicis1@deepv ~]$ ml
+srun -A deepsea -p dp-dam --gres=gpu:1 -t 1:0:0 --interactive --pty /bin/bash  # to start an interactive session on an DAM node exposig at least 1 GPU
+srun -A deepsea -p dp-dam --gres=gpu:2 -t 1:0:0 --interactive --pty /bin/bash  # to start an interactive session on an DAM node exposig 2 GPUs

+To compile and run Cuda applications on the Nvidia V100 cards included in the DAM nodes, it is necessary to load the CUDA module. It's advised to use the 2022 Stage to avoid
