5 NO, but I'm sure some devs are keenly aware of this feature in gcc-5.

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

34 Very cool, what you have done,
