The matrix list is out of date.  HMEM is also supported by verbs and shm providers, with limited GPU support by psm3 (CUDA only I think).  Most of the HMEM code is common between the verbs, shm, and efa providers.

Dear List,

The feature matrix shows support for device memory only on the efa provider and blank entries for the majority of other providers.

Looking at the github issues/PPRs it seems like a lot of work has been done on device memory - Are there 'experimental' branches out there that support device memory for other providers?
