8.6ms on spectral-norm. That's 3x faster than NumPy and the fastest result in this entire post. On n-body, 12.2x -- between Mypyc and Numba. Both results match the CPython baseline to 9 decimal places. This is single-threaded -- forcing one thread gave 9.1ms vs 8.6ms on spectral-norm.，这一点在谷歌中也有详细论述
When the Great Seal of the United States was finalized in 1782, it contained what the Founding Father’s held as the country’s most esteemed values. The eagle holds 13 arrows in its left talon and an olive branch in its right, its head turned toward the branch—the side which the eagle preferred to err on.。业内人士推荐博客作为进阶阅读
The branch predictor realization made it clear that this instruction was too dangerous to have anywhere in the code segment of any game – controlling when an instruction might be speculatively executed is too difficult. The branch predictor for indirect branches could, theoretically, predict any address, so there was no “safe place” to put an xdcbt instruction. And, if speculatively executed it would happily do an extended prefetch of whatever memory the specified registers happened to randomly contain. It was possible to reduce the risk, but not eliminate it, and it just wasn’t worth it. While Xbox 360 architecture discussions continue to mention the instruction I doubt that any games ever shipped with it.
