  We evolve floating point Sextic polynomial populations of genetic programming
binary trees for up to a million generations. Programs with almost four hundred
million instructions are created by crossover. To support unbounded Long-Term
Evolution Experiment LTEE GP we use both SIMD parallel AVX 512 bit instructions
and 48 threads to yield performance of up to 139 billion GP operations per
second, 139 giga GPops, on a single Intel Xeon Gold 6126 2.60GHz server.
