Hi Jeremy,

Thanks for the info!

In practice, no. hipcc attempts to read .hipInfo to determine the values 
of HIP_COMPILER and HIP_RUNTIME.

If .hipInfo is not found, hipcc will default to HIP_COMPILER=clang and 
HIP_RUNTIME=rocclr.
If HIP was built for AMD, .hipInfo will contain HIP_COMPILER=clang and 
HIP_RUNTIME=rocclr.
If HIP was built for NVIDIA, .hipInfo will contain HIP_COMPILER=nvcc and 
HIP_RUNTIME=cuda.

When building for the AMD runtime, .hipInfo is not necessary at all. 
When building for NVIDIA, if .hipInfo file is not available, you can 
specify the values with environment variables:

export HIP_PLATFORM=nvidia
export HIP_COMPILER=nvcc
export HIP_RUNTIME=cuda

Sincerely,
Cory Bloor
