Hello Stephan, Very interesting. You do know that both cephfs-0.94 and gcc-5.1.x have support for RDMA. It should really speed up some applications, particularly if you are running Apache:(spark|storm) or other "in-memory" codes on top of Apache-mesos (ebuild in BGO). The recently released (portage)t dev-java/sbt has gotten me much further along toward a working apache-spark ebuild, also in BGO. So things are "rocking" for low-latency, HPCC in gentoo. I only regret that somebody smarter than me is doing all of this..... NONE of the old gentoo linux cluster devs are much interested in putting together a gentoo cluster from 100% sources; and I find that most baffling, particularly Donnie Berkholz. Many are using clusters at their work, based on other distros but little effort is being expended to bring 100% source solutions for clustering to gentoo. I do find lots of solutions for containers on remote (vendor) clouds and binaries for hadoop and such. Nothing so that the rank and file gentoo communities can build their High Performance Computer Clusters, (HPCC) from 100% sources. Strange, real strange, at least from where I sit.... THANKS for the help. James James
