XOR SIMD
Introduction:
XOR code engine in pure Go.
High Performance: More than 270GB/s per physics core.
Performance
Performance depends mainly on:
CPU instruction extension.
Number of source row vectors.
Platform:
AWS c5d.xlarge (Intel(R) Xeon(R) Platinum 8124M CPU @ 3.00GHz)
All test run on a single Core.
I/O = (src_num + 1) * vector_size / cost

# Functions
Bytes XORs the bytes in a and b into a destination slice.
Bytes16 XORs of packed 16 Bytes.
Bytes16Align XORs of packed 16 Bytes.
Bytes8 XORs of 8 Bytes.
Bytes8Align XORs of 8 Bytes.
BytesA XORs the len(a) bytes in a and b into a destination slice.
BytesB XORs the len(b) bytes in a and b into a destination slice.
Encode encodes elements from source slice into a destination slice.
# Variables
EnableAVX512 may slow down CPU Clock (maybe not).
