Yes, let's keep it there, and I'm sure we'll find enough topics to
discuss with the group of people that are present (which I don't know

Here is an abstract/agenda for this time slot.  Are you going to put it
onto the wiki page, or want me to do it?

    This is an interactive BoF to discuss all things OMP (Offloading and
    Multi Processing): from front ends (programming abstractions: OpenMP,
    OpenACC, maybe CPLEX (C Parallel Language Extensions)?, others?) to
    support for heterogeneous offload targets/GCC back ends (Intel MIC,
    Nvidia PTX, HSA/HSAIL, GCN, others?) -- and everything in between:
    middle end abstractions.  Automatic vectorization, parallelization
    (parloops/autopar, graphite, polly, others?).  Compilation flow in
    GCC (LTO model, HSAIL model).  Issues with complex GCC build
    configuration, problems for packagers, GNU/Linux distributions.
