[libfabric-users] netdir / verbs interop

Thu Nov 12 12:41:01 PST 2020

Dear List,

Apologies if this question has been asked before, but I didn't see anything like it in the mailing list archive...

I must transfer data via RoCE between Linux and Windows using a SmartNIC to offload the CPU and bypass the OS kernel.  Both Linux and Windows machines will be equipped with Mellanox ConnectX-5 NICs.

My basic question is what libfabric providers must I use?  From reading the docs, I think I must use the verbs provider on Linux and the netdir provider on Windows.  Is this correct?

As a follow up, is the verbs provider supported on Windows?  I suspect not, but would like to confirm.

Thanks in advance,
