How to get the GPU execution time of a script in the shell?

I would like to display the completion time of a script, in terms of GPU time (not CPU). For the CPU, I can [simply](https://unix.stackexchange.com/q/52313/16704) [use](https://unix.stackexchange.com/q/52313/16704) [time](https://stackoverflow.com/q/556405/395857) : francky@gimmek80s:~$ time ls -l total 8 drwxrwxr-x 3 francky francky 4096 Dec 16 22:19 codes drwxrwxr-x 2 francky francky 4096 Jun 20 00:06 CUDA_practice drwxrwxr-x 3 francky francky 4096 Dec 16 22:44 data real 0m0.001s user 0m0.000s sys 0m0.000s What is the equivalent for GPUs? (I use the CUDA toolkit to perform some computations on my Nvidia GPUs.)
