I have looked a lot for publicly-available documentation for RDMA-capable NICs, but without success. AFAIK, Mellanox's datasheets (Programmer Reference Manuals - PRMs) are available to "customers with a design-in portfolio" under an NDA: https://community.mellanox.com/thread/1052. Can someone with more experience shed some light on this? For example, if I buy a Mellanox card, am I eligible for its PRM? --Anuj On Mon, Jun 22, 2015 at 6:04 PM, Brandon Falk <bfalk@xxxxxxxxxxxxxx> wrote: > Heya, > > I have a compute cluster which uses a completely custom OS (not binary > or source compatible with Linux by any means), and I'm really > interested in Infiniband support.
