module

info

Implements methods for querying the host target info.

You can import these APIs from the sys package. For example:

from sys import is_x86

Functions​

  • ​is_x86: Returns True if the host system architecture is X86 and False otherwise.
  • ​has_sse4: Returns True if the host system has sse4, otherwise returns False.
  • ​has_avx: Returns True if the host system has AVX, otherwise returns False.
  • ​has_avx2: Returns True if the host system has AVX2, otherwise returns False.
  • ​has_avx512f: Returns True if the host system has AVX512, otherwise returns False.
  • ​has_vnni: Returns True if the host system has avx512_vnni, otherwise returns False.
  • ​has_neon: Returns True if the host system has Neon support, otherwise returns False.
  • ​has_neon_int8_dotprod: Returns True if the host system has the Neon int8 dot product extension, otherwise returns False.
