Re: [openib-general] Infinipath support in OpenIB

Paul:

 The article states: 'InfiniPath will also support the OpenIB software stack 
 providing full InfiniBand compliance.'
 
 Is this something the OpenIB software developers are working on and 
 something that can be commented on in public, or should I speculate/ask 
 Pathscale?

Thanks for asking.  We are actively working on supporting OpenIB with the
help of the OpenIB community and hope to be able to submit code that
supports InfiniPath in the near future.

I would think that as long as they provide an HCA driver that registers with 
 the core layer and exposes the proper APIs, they would be able to run with 
the openib stack.  I do not know if their code is open source however.

Also interesting that OpenIB is suddenly an industry standard.  ;-)

Tom,

There's a reason for that -- when we asked customers, they asked us to
support OpenIB in particular. So congratulations, not only is OpenIB a
part of the IB ecosystem, it's one that everyone seems to want to
support.

We didn't want to invent a new flavor of verbs or DAPL anyway. No
point to it, no benefit to anyone.

-- greg
