They actually are, as is VTune and some other commercial stuff from intel and the open source libraries like ISA-L and IPP and frameworks like DPDK, SPDK and NV-DIMM stuff.. all work on FreeBSD.
Last I heard from my rep, intel was discontinuing icc altogether because it didn't make a lot of sense to not put the optimizations in the compilers most people use.. gcc, llvm, vcpp.
I'd assumed Intel kept their compilers as a competitive advantage even if they weren't profitable by themselves. Could certainly see it happening though.
This!
I’m a HPC sysadmin, and I used FreeBSD for all infrastructure services - DNS, DHCP, PF, ZFS based backup server et al
And strictly CentOS with tightly controlled installations of intel MKL libraries and its ecosystem.
