torch.set_flush_denormal
torch.set_flush_denormal(mode) -> bool
Disables denormal floating numbers on CPU.
Returns "True" if your system supports flushing denormal numbers
   and it successfully configures flush denormal mode.
   "set_flush_denormal()" is only supported on x86 architectures
   supporting SSE3.
Parameters:
      mode (bool) -- Controls whether to enable flush denormal
      mode or not
Example:
  >>> torch.set_flush_denormal(True)
  True
  >>> torch.tensor([1e-323], dtype=torch.float64)
  tensor([ 0.], dtype=torch.float64)
  >>> torch.set_flush_denormal(False)
  True
  >>> torch.tensor([1e-323], dtype=torch.float64)
  tensor(9.88131e-324 *
         [ 1.0000], dtype=torch.float64)
