How to exclude an OFI provider?

[JSCHO]

Greetings.

In IMPI 2021.14, it was possible to exclude the MLX provider by defining environment variable I_MPI_OFI_PROVIDER='^mlx'. However, in IMPI 2021.16.1 this results in the error:

libfabric:799566:1757052967::core:core:verify_filter_names():653<warn> provider ^mlx is unknown, misspelled or DL provider?

Why? How to exclude MLX in the current version?

thanks for reporting this, we will have a fix in a future version. In the meantime, please use FI_PROVIDER=^mlx if you want to exclude a certain provider.
