In case this is still an issue: For our A100s we use the CUDA_ARCH := 80. 86 is used for e.g. RTX 30* series GPUs and available starting 11.1 which indicates that the error source in your log was a lower CUDA version. For the CUDA MPI usage I have made the best experiences using the Nvidia HPC SDK which bundles CUDA and a matching MPI library.
