There is no 'simd' in your output. Does it mean you do not have simd
support?
SIMD is a generic term ("single instruction, multiple data") for the
ability of a single machine instruction to process multiple values of
the same type in parallel. Usually comes with a wide register set.
In intel-family architectures it could refer to any number of
architectural features/extensions including MMX (128 bit wide integer),
various versions of SSE (128 bit wide FP & integer), various versions
and flavors of AVX (128 bit to 512 bit wide FP & integer), etc.; other
architectures also have SIMD instructions as well.
All amd64 processors have at least SSE2 available.
