New CUDA 10.0 installation: missing nbody benchmark code?

I’m very new to the TX2 and CUDA.
I’m trying to run some benchmark tests so I can get familiar with the system.
I’ve installed CUDA 10.0 on the TX2.

I tried following the examples to run the nbody simulation benchmark, but when I navigate to the folder and run this command, I get an error:

./nbody_opengles -benchmark -fp64 -fullscreen -numbodies=1024

and the error:

-bash: ./nbody_opengles: No such file or directory

looking at the folder “nbody_opengles”, there’s not a benchmark file … is there a different benchmark file I should be running?

you have to build the sample codes before you can run them
