As I understand 'HPC', this list is more related to the 'performance' used in a scientific manner. We do not have a list tuning, so I would put hings from @performance rather into @tuning. Well, it's hard to express my point of view an this foreign language, so I hope I could make clear what I think. On the other hand, if @HPC is related to a more scientific view of 'performance', then it also can be retired since FreeBSD doe not play any role in scientific computing any more. No HPC compilers, not GPGPU support anywhere. Approximately ten years ago, when my former institute used FreeBSD as a HPC platform, we used NAGs math libraries and compilers natively offered for FreeBSD. With the dawn of the AMD/Intel amd64 architecture FreeBSD got more and more insignificant. Even the lack of 64Bit Linuxulator capabilities and therefore the inability of using Linux compilers and GPGPU software widended this gap. O. Hartmann
