Sorry Fernando, I just now saw this thread on an old thread. I think that 'sys-cluster/ceph' is where I'd like to test your spin on the gcc-5. Ceph has RDMA (RoCE) in the 0.94 branch (in portage). You are definately ahead of me on practical gcc-5 experiments with offloading and other new features. You did not list your second reference. Where I can I get/git your compiler and some brief suggestions on taking it for a test drive. I'm not much interested in the Intel simulator, atm. I like to test on old gear running gentoo:: borking is no big deal, if it happens. Other codes keen to test gcc-5 (offloading) on are Apache-mesos and Apache-spark and mesos-distcc. Also, per this doc [1] you can get your own gentoo overlay to put things up for wider experimentation, if you like.
