At GTC18 I mentioned that I created a script to run through all the samples in the CUDA Toolkit. I had a few moments so I thought I’d share the code. You can use the code below to loop through the sample files.
If you are interested in the results I obtained on VMs with the various profiles they are as follows:
- Original tests from a P4-4Q profile
- Tests from two VMs with P4-4Q profiles
- VM with P4 as a passthrough device
If you would like to use the code you’ll want to open up a text editor, like VI, on the system you wish to run this on then copy and paste this code into the file. Save and close the file (esc : wq). Set permissions on the file to make it executable (chmod +x <filename>). Once you’ve done that you can execute the script in a terminal with a ./<filename> command and let it run.
I offer it as is. The code doesn’t filter out non executable files so you will get messages like the following. “~/NVIDIA_CUDA-9.0_Samples/bin/x86_64/linux/release/FlowCPU.flo: Permission denied”
#!/bin/bash

Let me know if the script is helpful or if you run into any errors using it.
