what do you do? and for how many years

Running AVX-512 on all cores will lower all core operating frequency, in order to maintain the TDP of the processor.

When you run it in isolation, there's more headroom since only one core can run at the higher freq. and use AVX512 registers.

Also the power license ensures the cores running AVX512 code runs at a lower frequency.

Make sure to guard your AVX512 code block with VZEROUPPER when exiting it

which company was the one offering puzzle homework ?

How is this different from git clean -dxf .

yes, since Nehalem it was not publicly disclosed. Only the BIOS writer guide had these details. The Model Specific Register address and its bit value settings were not published, not all BIOS implementations exposed the 4 h/w prefetchers. In some CPUs they stayed disabled that way which made debugging more difficult.

very very cool ! Can you point to some links that you used to learn node, backbone.. what do you use for layout design ?
