 Give the file 'f':

 Here we can see that no GPU was allocated to us because we did not specify the ''%%--gres%%'' option
 <code>
-  kauffman3@bulldozer:~$ srun -p titan --pty /bin/bash
+user@bulldozer:~$ srun -p titan --pty /bin/bash
-  kauffman3@gpu3:~$ ./f 2>&1 | grep physical_device_desc
+user@gpu3:~$ ./f 2>&1 | grep physical_device_desc

 </code>
 If we request only 1 GPU.
 <code>
-  kauffman3@bulldozer:~$ srun -p titan --pty --gres=gpu:1 /bin/bash
+user@bulldozer:~$ srun -p titan --pty --gres=gpu:1 /bin/bash
-  kauffman3@gpu3:~$ ./f 2>&1 | grep physical_device_desc

+physical_device_desc: "device: 0, name: GeForce GTX 1080 Ti, pci bus id: 0000:19:00.0, compute capability: 6.1"
 </code>
 If we request 2 GPUs.
 <code>

 If we request more GPUs then are available.
