Re: @Disgusted Of Tunbridge Wells
Well, that one came as a surprise to me TBH but I checked, and you are correct.
Although, this particular CPU is being victimised because it is leading-edge in *double-precision* flops, which from the US POV is all about simulating nuclear weapons; and the only other reason is a (sorry) relatively small community of academic science HPC people to which I assume you belong?
But yes, there is a Tricky Issue here. The HPC community has decided, that it needs to prioritise a specialist technology (double-precision) that is dual-use with nuclear weapons. So it is absolutely not a coincidence that you are coming into conflict with the worlds nuclear hyperpower on this topic.
