This library seems to be open source and thus compileable with the channels toolchain. Is there a reason to use the redist?

Notes about publishing this recipe:

Source Hash

This package is source-available, but the source download from NVIDIA is hidden behind a developer login, and the download is unique to the user. Each time you download, the hash of the file changes, so it is not suitable for building automatically in a feedstock.

Dependencies

Some of the optional dependencies are not yet available on the channel including:

• libfabric >= 1.15.0.0 Add libfabric recipe #27988
• PMIx >= 3.1.5 Add openpmix, prrte #28225
• shmem?
• gdrcopy Maybe a kernel-driver is required which we can't ship
• Others... mellanox, nvlink, etc

TODO: Contact library team to discuss what features they think are appropriate for this conda package.
