           Summary: Enable both 32bit and 64bit libraries on dual-arch
                    systems (ppc64 and x86_64)
           Product: OpenFabrics Linux
           Version: 1.0rc5
          Platform: X86-64
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Verbs
        AssignedTo: bugzilla at openib.org
        ReportedBy: sp at scali.com


I've tested RC5, on a rhel4 u2 x86_64 platform.

Everything was fine (I had all the pre-req RPMs installed), however when trying
to install 32bit libraries and 64bit libraries at the same time, I get :

% rpm -i i386/libibverbs-1.0.3-0.i386.rpm
      file /etc/ld.so.conf.d/ofed.conf from install of libibverbs-1.0.3-0
conflicts with file from package libibverbs-1.0.3-0


Might I suggest renaming them to 'ofed-lib.conf' and 'ofed-lib64.conf' or
something in that order?

The OpenFabrics IB stack solves something people in HPC have been wanting for
some time, running 32bit applications natively on 64bit machines (64bit
kernels). By allowing the i386 and x86_64 RPMs to co-exist it enables that (and
it actually works to, at least with Scali MPI Connect which is what I'm
testing).

_Or_ a possible better solution would be to compile both 32bit and 64bit
libraries in the same package on x86_64 (I guess the same applies to ppc64) ?
