[gentoo-dev] Infiniband/OmniPath/iWARP and other RDMA related staff

Hi all!

I'm going to revive RDMA fabric related things in gentoo. And since its not 
only about infiniband staff but about more generic fabric types there is and 
idea to rename category sys-infiniband to more generic name. Suggestions are

sys-rdma
sys-fabric

What will be inside? It will be RDMA related stuff like OFED, fabric userspace 
drivers (verbs, psm, psm2, libfabric and others), plugins for specific devices, 
tools to flash RDMA cards and other related staff.

If sys-fabric name will be used, stuff like sys-cluster/knem
should go there too, imho. Probably this is not what intended, so
sys-rdma seems to be better name.

That would be wonderful, especially with the longstanding security issues 
against sys-infiniband/*.  Bugs 438444, 438446, 463338.

I hope your project goes well.  :)

This makes me happy. I've been playing with a standalone libfabric in my
overlay via the sockets/UDP providers, and had nothing but problems when I
tried to add USE flags for the various OFED bits (psm2 etc.)

An up-to-date libfabric that pulls in ofed only when needed would finally enable
people without the otherwise necessary fabric HW to write against the much more
usable & sane (when compared to raw IB verbs) libfabric APIs.

As far as the name is concerned IMHO fabric sounds less RDMA-specific;
I think the OFI WG now also prefers implementation-neutral terms.

cheers,
Holger

In current state i also preffer to rename it to 

sys-fabric 

and put all interconnect related stuff here (yes sys-cluster/knem  and sys-
cluster/open-mx also should go here)

So if there will be no objections i will do move in next 2 days
