The real question is: does Solaris have the same data structures required for

not, then perhaps a separate port will be required for Solaris to support the
dynamic SL functionality.
I know for sure that at some point OpenFabrics OpenSM has forked
and was used as a basis for *some* Solaris SM, which possibly
will preserve the same headers. The MAD format has to stay the
same to provide interoperability, and I doubt that someone renamed
MAD fields just for fun.
So the questions is, what header and what package contain there
structures.
Note there is no SM delivered with Solaris specifically. So there are
no SM specific header files.
AFAIK, we rely on remote SM's whether it is one running on a switch or
on another node (like OpenSM running on Linux).
So relying on OpenSM source headers existing on Solaris is probably a
bad plan.
However, it sounds like the existance of ib_types.h might help us which
I have answered in a previous email that it does exist.
I'm checking this offline with Oracle IB people.
Other question is do Oracle folks care about IB QoS and torus/mesh
topologies w.r.t. OMPI, because otherwise the dynamic SL is irrelevant.
It is not an extreme priority of ours but we would like to support it.

I'll check it, but my guess would be that Solaris doesn't have it.
AFAIK Solaris doesn't use OpenFabrics OpenSM - it has a separate
subnet manager, so I can't assume that it has.
So right now the dynamic SL will probably not work on Solaris
(though it won't break the compilation).
I have a pair of old machines running Solaris 11 Express (aka "SunOS 5.11 snv_151a
November 2010").
These have IB Verbs support, but there is no such header. In fact,
/usr/include/inifiband has no sub-directories.

(That is, no such header and not even any subdirectories on a very recent
version of Solaris 11: snv_168.)
Makes sense. But I believe that these Solaris installations
just don't have Subnet Manager, so they are not supposed to
have these headers anyway. What I don't know is what headers
are installed as part of the SM installation.
Does anybody have a Solaris machine with Subnet Manager?

I may be able to do some testing eventually, but now is not a good time.
