nvprof is deprecated

[Imss27]

======== Warning: This version of nvprof doesn't support the underlying device, GPU profiling skipped
======== Warning: nvprof is not supported on devices with compute capability 8.0 and higher.

So I suggest an update of using another profiler.

You could use nsys nvprof instead like nsys nvprof ./vector_add referred to the official docs of Nsight systems
