[openib-general] DAPL for openib

[Masanori ITOH]

Hi all,

I also have a working implementation of u/kDAPL on top of OpenIB stack.
It's based on the beta2.04 of reference implementation and the OpenIB uDAPL
contained in ib-support-2.0 tar ball.
The kDAPL portion uses the gen1 OpenIB API.
The uDAPL portion is just a porting of OpenIB uDAPL into the beta2.04 and
so still contains VAPI dependent codes.

Although my u/kDAPL is still a quick hack thing, but anyway
I succeeded to run some performance test programs and a DAFS server/client
suite.
I think my work also can be a start point of the pure OpenIB u/kDAPL
development, and I'm talking with my bosses making that public in these days.

Which 'gen1' API and 'gen2' API do you mean?
'gen1' of Voltaire stack, and 'gen2' of OpenIB stack?

I was also thinking about that.
