There's a big difference. Apple explicitly targeted those markets (music players, phones, etc.) with their products. They have NEVER targeted HPC, and have entirely backed away from anything that looks like a server. So Anon's statement is quite reasonable.

Uh huh. Like all these:

Apple is good, but they are hardly perfect. Plenty of their products and software have been poor in comparison to the alternatives. But that's true of most companies. Apple excels in that they have a high success rate (not perfect though) and have an uncanny ability to shape how consumer preference (and thus markets) will evolve. That necessarily involves taking risks, which means you sometimes fail.

It's very much on topic, but it would be good if you didn't hijack the thread. Honestly the topic seems important enough to merit its own thread.

Honestly, I've seen a few macroscalar articles, but they all seem to ignore the ~50 years of previous compiler tricks. Many of which are techniques for aggressively scheduling loops in parallel.
