Dear experts,
I am getting the following error while doing YPP calculations for band structure:

The error file is as follows:
The library attempted to open the following supporting CUDA libraries,
but each of them failed. CUDA-aware support is disabled.

If you are not interested in CUDA-aware support, then run with
--mca opal_warn_on_missing_libcuda 0 to suppress this message. If you are interested
in CUDA-aware support, then try setting LD_LIBRARY_PATH to the location
of libcuda.so.1 to get passed this issue.

Dear Dhanjit,

it seems an I/O problem, can you try to reduce the number of bands to be interpolated? e.g. from 72 to 77?

Best,

Daniele

Dear Daniele,
I tried reducing the number of bands and it worked.
Thank you for helping me out.
