[ofiwg] Draft proposal for the SC15 libfabric BoF

[Bernard Metzler]

So, the caption of that slide is probably misleading. ibverbs as an
interface is in fact being extended in the OFV WG. I suggest not to do a
comparative discussion with ibverbs here at all, but lay out the facts the
group thinks matter to make kfabrics a good fit.

Caption: kfabrics benefits.

o transport neutral
o minimal requirements on endpoint resources
o no heavyweight connection mechanism for local NVM access


Thanks,
Bernard.

I, too, agree.  The comments about verbs in the BoF proposal are based on
this slide, currently being developed by DS/DA:

OFI WG came to a similar set of conclusions.   I strongly support the work
going on in OFV WG.  OFV WG is not mentioned in the BoF proposal at all.

Gilad, I agree.

We as an alliance comprising multiple working groups should never promote
public bashing among those groups. This should not preclude constructive
discussion though.

Thanks,
Bernard.

Thanks for sending Paul.

I am not sure I understand why you suggest that the verbs API is not
something that fit the needs of applications. The API was created with the
RDMA network architecture to meet the needs of applications and it is
proven in many systems installations, and it supports both InfiniBand and
Ethernet. OFI is yet to be proved on a single system.

As long as OFA supports the development of OFI and OFV, I think that we
need to be careful not to have negative view on neither  of them. If you
want to focus on OFI that is fine, but there is no need to say it is the
better option. The opposite can also be said.
