Does the virtual machine lack some flags, which affects the correctness of CPU computing?

Virtual machine is missing the following flags:

  • avx512dq
  • avx512bw
  • avx512vl

Some libraries (such as MKL) choose AVX2 Implementation if not all of the AVX512 flags are found.

After we use apt-get install linux-image to update the kernel, we solve this problem
