I am sorry for the missing info. Do you need the specific CPU model?
Below is some helpful additional information:
1. We have tested the codes on different Intel X86_64 architectures,
and the codes were platform-agnostic, which means they could be
enabled and run when the CPUs support AVX2 or AVX512 instructions
set, or they would be disabled.
2. We have tested the codes both on Linux and Windows operating systems.
3. In the CPU that only supports the AVX2 instructions set, we use the
common instructions to emulate some features introduced by AVX51
to keep compatibility.

Best regards.
