Most of those groups used FreeBSD changed to Linux (mostly Redhat, some Ubuntu). Watching Phoronix and their benchmarks speaks clear what OS is the first choice. Well, I like the staright forward, centralised organization and the academic heritage of the BSDs and I would miss ZFS. The essence is: there is no serious reason to convince compiler vendors or vendors of 3D graphics chips of supporting FreeBSD for a specific purpose if there is no need -statistically. AMD/ATi in conjunction with OpenCL/LLVM was a great hope since the GPU vendor offered 3D specs of their chips to opensource vendors. But on the other hand nVidia seems to be much better supported by Gallium3D these days although they haven't offered internal 3d specs. I'm confused and at the end I have to decide. At the moment the comunity of astronomers and astrophysicist is sharing several very interesting N-body simulation code based on CUDA (open source) but users and maybe rare scientists still using FreeBSD are excluded from using those benefits.
